The incidence of veno occlusive disease （VOD） after STC ranges from 0 to 70%, but is decreasing. Survival is good when VOD is a mild form, but when it is severe and associated with an increase of hepatic venous pressure gradient 〉 20 mmHg, and mortality is about 90%. Prevention remains the best therapeutic strategy, by using non-myeloablative conditioning regimens before STC. Prophylactic administration of ursodeoxycholic add, being an antioxidant and antiapoptotic agent, can have some benefit in reducing overall mortality. Defibrotide, which has pro-fibrinolytic and antithrombotic properties, is the most effective therapy; decompression of the sinusoids by a b-ansjugular intrahepatic portosystemic shunt （TIPS） can be tried, especially to treat VOD after liver transplantation and when multiorgan failure （HOF） is not present. Liver transplantation can be the last option, but can not be considered a standard rescue therapy, because usually the concomitant presence of multiorgan failure contraindicates this procedure.展开更多

Methods We enrolled 7 patients who had Graves＇ disease （GD） with IAOLs screened and evidenced by transcranial Doppler, then further confirmed with digital substract angiography in 2 patients and magnetic resonance angiography in 5 patients. Brain magnetic resonance imaging （MRI） was performed in all 7 patients. Three patients were followed up. Results Among 7 patients, 1 was male and 6 were females. The mean age was 32.0 ± 5.5 （ range from 11 to 49） years old. Six of them had symptoms of GD but one was asymptomatic with abnormality of I3, T4, and thyroid stimulating hormone. The lesions of intracranial arteries were symmetrical bilaterally in the intemal carotid artery system in 6 patients, as well as asymmetrical in 1 patient. Terminal internal carotid artery （TICA） were involved in all 7 patients. Middle cerebral artery （MCA） were involved in 3, anterior cerebral artery in 2, and basilar artery in 1 patient. Net-like collateral vessels and mimic moyamoya disease were observed in the vicinity of the occlusive arteries in 2 patients. All patients presented symptoms of ischemic stroke including transient ischemic attack and/or infarction while IA- OLs were found. Three patients had obvious involuntary movements. Brain MRI revealed infarctions located in the cortex, basal ganglion, or hemiovular center in 5 patients. The remaining 2 patients had normal brain MRI. The neurological symptoms were improved concomitant with relief of the thyroid function in 2 patients, while IAOLs were aggravated with deterioration of the thyroid function in 1 patient. Conclusion IAOLs in patients with GD mainly involve intracranial arteries, especially the TICA and MCA, which is similar to moyamoya disease. The neurological symptoms and severity of involved arteries may relieve while the hyperthyroidism is gradually under control.展开更多

All of the original articles were evaluated according to date of publications, countries, clinics and topics. Studies about occlusive vascular diseases were evaluated according to their qualifications, review methods and results. SPSS for Windows 16.0 was used in data analysis and data were expressed as mean, standard deviation and percentage.RESULTS: A total of 735 original research articles were investigated. The number of publications have shown a regular logarithmic increase over the years. Thirty-two percent of all publications were performed by clinics in Turkey and 56.4% were performed by general-oncological surgery and cardiology clinics. A total of 107 publications were identified to be about occlusive vascular diseases, 80.3% of these publications were found to be prognostic and 19.6% to be diagnostic, 82.2% of them were found to be planned as retrospective and 17.7% as prospective. In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.展开更多

Methods: SLN and NLC were prepared by high shear homogenization and characterized by size, polydispersity index, zeta potential, morphology and physical stability. Occlusive effect was assessed by an in vitro test and by measuring TEWL using pig skin. Skin treated with the lipid carriers was visualized by SEM. A penetration test through skin, followed by tape stripping, was carried out using Nile red as a marker. Results: SLN (200 ± 6 nm) and NLC (192 ± 11 nm) were obtained. An occlusion factor of 36% - 39% was observed for both systems, while a reduction in TEWL of 34.3% ± 14.8% and 26.2% ± 6.5% was seen after treatment with SLN and NLC, respectively. SEM images showed a film formed by the lipid carriers, responsible for the occlusion observed. No differences were found between the occlusive effect produced by SLN and NLC in both tests. NLC allowed the penetration of a greater amount of Nile red than SLN: 4.7 ± 1.3 μg and 1.7 ± 0.4 μg, respectively. Conclusion: Both carriers form a film on the skin, providing an occlusive effect with no differences between these two systems. The penetration of a marker (Nile red) into the stratum corneum was quite higher for NLC than for SLN, suggesting an influence of the composition of these particles on their penetration enhancing ability.展开更多

To review our preliminary experience and evaluate our early results of a combined intraoperative iliac angioplasty and stenting with infrainguinal revascularization in multilevel atherosclerotic occlusive disease. Methods. From July 1999 to April 2000, intraoperative iliac angioplasty and stenting combined with simultaneous femoro- popliteal bypass were performed on 12 lower extremities of 10 patients suffering from multilevel atherosclerotic occlusive disease. There were 8 men and 2 women, average 72 years. The indications for procedures included disabling claudication in 3 and rest pain in 7 patients. Results. Eleven iliac angioplasty and stent procedures combined with simultaneous 9 femoro- popliteal bypass and 3 femoro- femoral- popliteal bypass were performed in 12 limbs of 10 patients. Angioplasty and stent placement was technically successful in all patients. One contralateral femoral- popliteal bypass was failure after femorofemoral- popliteal bypass. There were no additional instances of procedural or postoperative morbidity or mortali- ty. Mean follow- up was 5 months (range 1～ 10 months). During the follow- up period, one femoro- infrapopliteal graft became occluded after 7 months and above- knee amputation was required. The cumulative primary patency rate of stented iliac arteries, femoro- femoral bypass grafts and femoro- popliteal bypass grafts were 100％ (11/11), 100％ (3/3) and 90.9％ (10/11) in the follow- up period, respectively. The amputation rate was 8.3％ (1/12). Conclusions. Intraoperative iliac artery PTA and stent placement can be safely and effectively performed simultaneously with infrainguinal revascularization for multilevel atherosclerotic occlusive disease by skilled vascular surgeon, using a portable C arm fluoroscopy in the operating room. Furthermore, iliac artery PTA and stenting was valuable adjunct to distal bypass either to improve inflow and outflow, or to reduce the extent of traditional surgical intervention, and also, any angioplasty and stenting- related complications can be immediately corrected as well.展开更多

Methods Clinical information of 9 cases suffering from lower extremity arterial occlusion and CD was investigated retrospectively. Results All the cases were less than 50 years old and the most were females (8/9). Arterial occlusions occurred in either active (5/9) or inactive (4/9) stage of CD. Besides the arteries of lower extremities, other arteries could also be involved such as aorta, iliac artery, renal artery or mesentery artery. Seven cases had atherosclerotic imaging findings (4 had aortic plaques and 6 had iliac artery stenoses). Embolectomy or thromboendarterectomy were mostly performed. Four (44.4%) cases had recurrent lower limb ischemia. Conclusions Arterial occlusive disease is a rare extraintestinal manifestation of CD. A thorough inspection of aorta is necessary. Embolectomy is mostly preferred. Anticoagulation treatment is highly recommended after the operation.展开更多

Recently, there had been a significant shift towards lower limb revascularization using endoluminal techniques. However, previously available data evaluating the long leg bypass or combined endoluminal and bypass procedures have been too anatomically heterogeneous to be easily applied to patients with infrainguinal disease and tissue loss. Clinical decision making in Complex multilevel or diffuse peripheral arterial occlusive disease with multiple co-morbidities especially associated coronary arterial disease is challenging. We describe twelve patients of iliofemoral arterial occlusive disease with tibiopopliteal arterial occlusive disease along with multiple co-morbidities like coronary arterial disease and diabetes mellitus who showed marked improvement with minimal post-operative?morbidities after iliofemoral or ileopopliteal bypass grafting with endarterectomy of the tibiopopliteal segment and related review of the literature.展开更多

He had been admitted 6 days previously for nausea, vomiting, diarrhea, fever, asthenia since the onset of dyspnea with 89% desaturation in ambient air and a dry cough. A diagnosis of gastroenteritis was made and treated without success. The appearance of abdominal distension and bloating motivated his transfer to the CTPI where the rRT-PCR was carried out positive and an X-ray of the abdomen without preparation which had demonstrated a significant aerocoly with agglutination of handle. Surgical management under general anesthesia found a clean cavity after coeliotomy, multiple intestino-intestinal, intestino-parietal and omentum-parietal adhesions. The gesture consisted of an adhesiolysis, omentectomy. The postoperative follow-up was favorable with resumption of transit on D5 postoperative. Put under the COVID-19 treatment protocol, the rRT-PCR was negative on D13, output on D14 and removal of the D19 files without postoperative complications.展开更多

Methods： A total of 110 inpatients with ASO who performed Superficial femoral artery stent implantation were randomly divided into observation group and control group, with 55 cases in each group.Both groups received Aspirin 100 mg/d and Clopidogrel 75 mg/d. The observation group was given Furongtongmai capsule on the basis of routine treatment. After continuous treatment for 6 months, the clinical efficacy, Ankle Brachial Index （ABI）, high-sensitivity C-reactive protein （Hs-CPR） and ISR were compared between the two groups. Results： At 6 months after operation, the plasma levels of Hs-CRP in the two groups were significantly lower than those in the control group （P 〈 0.05）. The ABI of treatment group was significantly higher than the control group （P 〈 0.05）. There was a statistically significant difference in ISR incidence between the treatment group and the control group 6 months after surgery （9.09% vs 27.78%, P 〈 0.05）. Conclusion： Furongtongmai Capsule can inhibit Hs-CRP in patients with ASO after femoral artery intervention, improve the ankle brachial index and reduce the incidence of ISR.展开更多

Vaso occlusive crisis (VOC) is frequently seen in such patients. Painful VOC is usually recurrent, of variable severity due to many factors and its management poses important challenge in the clinical practice. Few patients do not respond to standard therapies and continue to suffer severe pain for prolonged period or land to serious life threatening situation. The red cell exchange by aphaeresis is presumed to be one efficient alternative in this situation which can reduce the level of HbS below 40% - 50%. However, it is costly and not available everywhere. Both circumstances are common in our state where incidence of sickle cell disease is quite high. In such situations simple red cell exchange i.e. removing 1 unit (350 ml) of blood manually (by phlebotomy) and replacement with one unit normal red cell is effective. All of our four cases of SCA with severe acute VOC, are not responding to standard therapy but responded efficiently to this simple red cell exchange transfusion. Our present observation may pave the way of one simple, affordable, and effective measure to reduce the pain of severe acute VOC not responding to standard therapy. Moderate reduction of HbS by 8% - 14% by simple red cell exchange transfusion was associated with relief of pain of acute VOC;a new observation was reported in all our 4 cases which need to be validated by larger controlled studies.展开更多

Methods： Fifty-six cases of simple atherosclerotic occlusive disease of lower extremity were divided into 3 types according to the location of occhision, including 17 cases of abdominal aorta-iliac artery, 18 cases of iliac-femoral artery, and 21 cases of inferior popliteal artery. Catheter and guide wire combined with blunt dissection and subtle banding were used to dredge the occluded vessels, and stents were implanted when interlayer appeared. Results： After the treatment, 46 cases of occlusion were dredged （82.1%）, 6 cases remained occluded with the same symptoms （10.7%）, and 4 cases had severer symptoms （7.1%）. Among the 46 successful cases, there were 16 cases of abdominal aorta-iliac artery （94.1%）, 16 cases of iliac-femoral artery （88.9%） and 14 cases of inferior popliteal artery, artery （66.6%）. There was no statistical difference between the abdominal aorta-iliac artery cases and iliac-femoral artery cases （P〉0.05）, but there was statistical difference between these two types and the inferior popliteal artery cases （P〈0.05）. In the successful cases, 9 cases of abdominal aorta-iliac artery （52.9%）, 10 cases of iliac-femoral artery （55.5%） and 10 cases of inferior popliteal artery （33.3%） had 5-10 cm of occlusion, with no statistical difference between the first two types （P〉0.05）, but with statistical difference between the first two types and the third type （P〈0.05）. Compared with the 14 dredged cases （71.4%）, the 7 cases （33.3%） of inferior popliteal artery cases had richer compensatory circulation （P〈0.05）. Conclusion： It＇s safe and effective to treat simple atherosclerotic occlusive disease of the lower extremity with interventional therapy. The location and length of occlusion and the abundance of compensatory circulation had effect on the therapy.展开更多

Methods: Balloon angioplasty was attempted in 25 arteries with chronic total occlusion, with the mean time of occlusion of 17±13 months (ranging from 2 to 84 months) and mean length of 14±6 mm (ranging from 5 to 25 mm). The morphology of the lesions included bridging collaterals (4 cases), calcification (3 cases) and major side branch at the lesion (4 cases) . Choice PT?wire was used electively in all the cases. Results: Lesion was crossed successfully in 92% (23/25) cases, without incidences of dissection of the coronary artery with subintimal entry. Balloon angioplasy and stenting (n = 21) were performed with good immediate angiograghic results. Acute myocardial infarction or death occurred in none of the patients. Conclusion Successful recanalization of chronic coronary total occlusions using Choice PTTM wire can be achieved with good safety.展开更多

Methods: 30 patients with suspected lower limb vascular occlusive disease admitted to our hospital from May 2021 to January 2022 were included. The examinations received in the hospital included CTA imaging and digital subtraction angiography. The later examination results were the gold standard to evaluate the diagnostic efficacy of CTA imaging in lower limb vascular occlusive disease. Results: in this group, 27 suspected cases of lower extremity vascular diseases were confirmed by digital subtraction angiography, including 7 cases of lower extremity vascular occlusion, 20 cases of lower extremity vascular stenosis (8 cases of severe, 8 cases of moderate, 4 cases of mild), 26 cases of lower extremity vascular diseases diagnosed by CTA, 7 cases of lower extremity vascular occlusion, 19 cases of lower extremity vascular stenosis (7 cases of severe, 8 cases of moderate, 4 cases of mild). There was no statistical difference in the detection rate of disease types between the two examination methods (P > 0.05). With reference to digital subtraction angiography, the coincidence rate, specificity and sensitivity of CTA imaging in the diagnosis of lower limb vascular occlusive diseases were 96.67%, 100.00% and 96.30% respectively. Conclusion: the sensitivity and specificity of CTA in the diagnosis of lower extremity vascular occlusive disease are both high.展开更多
文摘BACKGROUND Lower limb atherosclerotic occlusive disease(LAOD)is a common complication in diabetic patients,leading to significant symptoms and reduced quality of life.AIM To investigate the efficacy of autologous platelet-rich gel(APRG)as an innovative treatment for LAOD,focusing on clinical outcomes such as symptom relief,flow values,ankle-brachial index(ABI),walking distance,and claudication severity.METHODS This retrospective study involved an analysis of electronic medical records(EMR)from 150 patients diagnosed with LAOD.Participants were assigned to either a treatment group(n=80)or a control group(n=70).Both groups received standard care and underwent dressing changes.In addition,the treatment group was given APRG.Primary outcomes included changes in pain levels,wound healing rates,flow values assessed by plethysmography,ABI measurements,walking distance,and claudication severity.Statistical analyses were conducted to determine the significance of the results.RESULTS The APRG group showed significant improvements after 12 weeks,including a 70%reduction in pain,a 65%increase in wound healing rates,and an average walking distance increase of 150 meters.Flow values improved by 20%,with significant enhancements in ABI measurements(P<0.01).Additionally,patient satisfaction was higher,and 60%of patients reported improved claudication severity,confirming the efficacy of APRG in enhancing clinical outcomes for lower LAOD.CONCLUSION The APRG demonstrates significant efficacy in managing LAOD in diabetic patients,improving key clinical parameters including flow values,ABI,walking distance,and claudication.These findings support the need for further prospective studies to validate long-term efficacy and optimize treatment strategies.
文摘Hepatic veno-occlusive disease is a clinical syndrome characterized by hepatomegaly, ascites, weight gain and jaundice, due to sinusoidal congestion which can be caused by alkaloid ingestion, but the most frequent cause is haematopoietic stem cell transplantation （STC） and is also seen after solid organ transplantation. The incidence of veno occlusive disease （VOD） after STC ranges from 0 to 70%, but is decreasing. Survival is good when VOD is a mild form, but when it is severe and associated with an increase of hepatic venous pressure gradient 〉 20 mmHg, and mortality is about 90%. Prevention remains the best therapeutic strategy, by using non-myeloablative conditioning regimens before STC. Prophylactic administration of ursodeoxycholic add, being an antioxidant and antiapoptotic agent, can have some benefit in reducing overall mortality. Defibrotide, which has pro-fibrinolytic and antithrombotic properties, is the most effective therapy; decompression of the sinusoids by a b-ansjugular intrahepatic portosystemic shunt （TIPS） can be tried, especially to treat VOD after liver transplantation and when multiorgan failure （HOF） is not present. Liver transplantation can be the last option, but can not be considered a standard rescue therapy, because usually the concomitant presence of multiorgan failure contraindicates this procedure.
文摘Objective To investigate the distribution and clinical manifestations of intracranial arterial occlusive lesions （IA- OLs）, and their correlation with thyroid function. Methods We enrolled 7 patients who had Graves＇ disease （GD） with IAOLs screened and evidenced by transcranial Doppler, then further confirmed with digital substract angiography in 2 patients and magnetic resonance angiography in 5 patients. Brain magnetic resonance imaging （MRI） was performed in all 7 patients. Three patients were followed up. Results Among 7 patients, 1 was male and 6 were females. The mean age was 32.0 ± 5.5 （ range from 11 to 49） years old. Six of them had symptoms of GD but one was asymptomatic with abnormality of I3, T4, and thyroid stimulating hormone. The lesions of intracranial arteries were symmetrical bilaterally in the intemal carotid artery system in 6 patients, as well as asymmetrical in 1 patient. Terminal internal carotid artery （TICA） were involved in all 7 patients. Middle cerebral artery （MCA） were involved in 3, anterior cerebral artery in 2, and basilar artery in 1 patient. Net-like collateral vessels and mimic moyamoya disease were observed in the vicinity of the occlusive arteries in 2 patients. All patients presented symptoms of ischemic stroke including transient ischemic attack and/or infarction while IA- OLs were found. Three patients had obvious involuntary movements. Brain MRI revealed infarctions located in the cortex, basal ganglion, or hemiovular center in 5 patients. The remaining 2 patients had normal brain MRI. The neurological symptoms were improved concomitant with relief of the thyroid function in 2 patients, while IAOLs were aggravated with deterioration of the thyroid function in 1 patient. Conclusion IAOLs in patients with GD mainly involve intracranial arteries, especially the TICA and MCA, which is similar to moyamoya disease. The neurological symptoms and severity of involved arteries may relieve while the hyperthyroidism is gradually under control.
文摘BACKGROUND: This study aims to evaluate the results of studies investigating neutrophilto-lymphocyte ratio(NLR) and to identify the prognostic and diagnostic value of NLR in occlusive vascular diseases.METHODS: With the aim of identifying the studies related to NLR, a search was performed on http://www.ncbi.nlm.nih.gov/pubmed by using the key words "neutrophil lymphocyte ratio" between January 2005 and December 2014. All of the original articles were evaluated according to date of publications, countries, clinics and topics. Studies about occlusive vascular diseases were evaluated according to their qualifications, review methods and results. SPSS for Windows 16.0 was used in data analysis and data were expressed as mean, standard deviation and percentage.RESULTS: A total of 735 original research articles were investigated. The number of publications have shown a regular logarithmic increase over the years. Thirty-two percent of all publications were performed by clinics in Turkey and 56.4% were performed by general-oncological surgery and cardiology clinics. A total of 107 publications were identified to be about occlusive vascular diseases, 80.3% of these publications were found to be prognostic and 19.6% to be diagnostic, 82.2% of them were found to be planned as retrospective and 17.7% as prospective. In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.
文摘Objective: This work compares the occlusive effect and the penetration enhancement ability of solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC), through in vitro skin. Methods: SLN and NLC were prepared by high shear homogenization and characterized by size, polydispersity index, zeta potential, morphology and physical stability. Occlusive effect was assessed by an in vitro test and by measuring TEWL using pig skin. Skin treated with the lipid carriers was visualized by SEM. A penetration test through skin, followed by tape stripping, was carried out using Nile red as a marker. Results: SLN (200 ± 6 nm) and NLC (192 ± 11 nm) were obtained. An occlusion factor of 36% - 39% was observed for both systems, while a reduction in TEWL of 34.3% ± 14.8% and 26.2% ± 6.5% was seen after treatment with SLN and NLC, respectively. SEM images showed a film formed by the lipid carriers, responsible for the occlusion observed. No differences were found between the occlusive effect produced by SLN and NLC in both tests. NLC allowed the penetration of a greater amount of Nile red than SLN: 4.7 ± 1.3 μg and 1.7 ± 0.4 μg, respectively. Conclusion: Both carriers form a film on the skin, providing an occlusive effect with no differences between these two systems. The penetration of a marker (Nile red) into the stratum corneum was quite higher for NLC than for SLN, suggesting an influence of the composition of these particles on their penetration enhancing ability.
文摘Objectives To assess the clinical efficacy,safety,and feasibility of autologous transplantation of mobilized peripheral blood mononuclear cells(PBMNCs)for patients with peripheral arterial occlusive disease(PAOD)of the lower extremity.Methods A total of 152 patients with PAOD of the lower extremity were enrolled into this non-controlled observational study from November 2003 to March 2006.All patients received subcutaneous injections of recombinant human granulocyte colony-stimulating factor(G-CSF,450-600μg/day)for 5 days in order to mobilize stem/progenitor cells;their PBMNCs were collected and transplanted by multiple intramuscular injections into ischemic limbs.Patients were followed up for at least 12 weeks.Results At 12 weeks,primary manifestations,including lower limb pain and coldness,were significantly improved in 137(90.1%)of the patients;limb ulcers improved or healed in 46(86.8%)of the 53 patients,while 25 of the 48(47.9%)patients with limb gangrene remained steady or improved.Ankle-brachial index(ABI)improved in 33(22%)of the cases,and TcPO_(2) increased in 45(30%)of the cases.Angiography before treatment,and at 12 weeks after treatment,was performed in 10 of the patients and showed formation of new collateral vessels.No severe adverse effects or complications specifically related to cell transplantation were observed.Conclusion Autologous transplantation of G-CSF-mobilized PBMNCs might be a safe and effective treatment for lower limb ischemic disorder.
文摘Objective. To review our preliminary experience and evaluate our early results of a combined intraoperative iliac angioplasty and stenting with infrainguinal revascularization in multilevel atherosclerotic occlusive disease. Methods. From July 1999 to April 2000, intraoperative iliac angioplasty and stenting combined with simultaneous femoro- popliteal bypass were performed on 12 lower extremities of 10 patients suffering from multilevel atherosclerotic occlusive disease. There were 8 men and 2 women, average 72 years. The indications for procedures included disabling claudication in 3 and rest pain in 7 patients. Results. Eleven iliac angioplasty and stent procedures combined with simultaneous 9 femoro- popliteal bypass and 3 femoro- femoral- popliteal bypass were performed in 12 limbs of 10 patients. Angioplasty and stent placement was technically successful in all patients. One contralateral femoral- popliteal bypass was failure after femorofemoral- popliteal bypass. There were no additional instances of procedural or postoperative morbidity or mortali- ty. Mean follow- up was 5 months (range 1～ 10 months). During the follow- up period, one femoro- infrapopliteal graft became occluded after 7 months and above- knee amputation was required. The cumulative primary patency rate of stented iliac arteries, femoro- femoral bypass grafts and femoro- popliteal bypass grafts were 100％ (11/11), 100％ (3/3) and 90.9％ (10/11) in the follow- up period, respectively. The amputation rate was 8.3％ (1/12). Conclusions. Intraoperative iliac artery PTA and stent placement can be safely and effectively performed simultaneously with infrainguinal revascularization for multilevel atherosclerotic occlusive disease by skilled vascular surgeon, using a portable C arm fluoroscopy in the operating room. Furthermore, iliac artery PTA and stenting was valuable adjunct to distal bypass either to improve inflow and outflow, or to reduce the extent of traditional surgical intervention, and also, any angioplasty and stenting- related complications can be immediately corrected as well.
文摘Objective To investigate the clinical characteristics and treatment strategy of lower extremity arterial occlusive disease in patients with Crohn's disease (CD). Methods Clinical information of 9 cases suffering from lower extremity arterial occlusion and CD was investigated retrospectively. Results All the cases were less than 50 years old and the most were females (8/9). Arterial occlusions occurred in either active (5/9) or inactive (4/9) stage of CD. Besides the arteries of lower extremities, other arteries could also be involved such as aorta, iliac artery, renal artery or mesentery artery. Seven cases had atherosclerotic imaging findings (4 had aortic plaques and 6 had iliac artery stenoses). Embolectomy or thromboendarterectomy were mostly performed. Four (44.4%) cases had recurrent lower limb ischemia. Conclusions Arterial occlusive disease is a rare extraintestinal manifestation of CD. A thorough inspection of aorta is necessary. Embolectomy is mostly preferred. Anticoagulation treatment is highly recommended after the operation.

文摘Objective:To systematically evaluate the clinical efficacy and safety of Simiao Yong'an Decoction in the treatment of peripheral occlusive disease(PAOD).Methods:Eight randomized controlled clinical trials(RCT)of Simiao Yong'an Decoction in the treatment of PAOD were searched and screened from domestic and foreign databases(all from database construction to March 2020).The quality of the retrieved original studies was evaluated according to the evaluation criteria of Cochrane Handbook 5.1.0,and the included studies were meta-analyzed by RevMan5.3 software.Results:A total of 350 articles were retrieved,among which 14 studies met the inclusion criteria,with a total sample size of 1254 cases.The results of meta-analysis showed that:compared with conventional western Med,combined with Simiao Yong'an Decoction on the basis of western Med treatment can significantly improve the total clinical response rate of patients[RR=1.20,95%CI(1.14,1.27),P<0.00001],improve ankle brachial index(ABI)level[MD=0.79,95%CI(0.66,0.92),P<0.00001]and toe brachial index(TBI)level[RR=0.13,95%CI(0.10,0.16),P<0.00001],decreased c-reactive protein levels[MD=-8.55,95%CI(-8.99,-8.11),P<0.00001]and LDL levels[MD=-0.41,95%CI(-0.62,-0.19),P=0.0002],and increased HDL levels[MD=0.32(0.22,0.43),P<0.00001].There was no statistically significant difference in the incidence of adverse reactions[RR=0.50,95%CI(1.15,1.64),P=0.25].Conclusion:Simiao Yong'an Decoction combined with conventional western Med is more effective than conventional western Med in the treatment of PAOD.However,in view of the limitations of the quality of the analyzed literature,the positive results obtained in this study still need to be further verified by a large sample and multi-center clinical trial with a reliable research program.
文摘Importance of?thrombendarterectomy (TEA) had declined with the advent of bypass techniques and availability of prosthetic grafts, in patients with Peripheral arterial occlusive disease (PAOD). Recently, there had been a significant shift towards lower limb revascularization using endoluminal techniques. However, previously available data evaluating the long leg bypass or combined endoluminal and bypass procedures have been too anatomically heterogeneous to be easily applied to patients with infrainguinal disease and tissue loss. Clinical decision making in Complex multilevel or diffuse peripheral arterial occlusive disease with multiple co-morbidities especially associated coronary arterial disease is challenging. We describe twelve patients of iliofemoral arterial occlusive disease with tibiopopliteal arterial occlusive disease along with multiple co-morbidities like coronary arterial disease and diabetes mellitus who showed marked improvement with minimal post-operative?morbidities after iliofemoral or ileopopliteal bypass grafting with endarterectomy of the tibiopopliteal segment and related review of the literature.
文摘We report the case of a 39-year-old patient with a history of chronic gastritis, functional colopathy and appendectomy, referred by another public institution for severe abdominal pain. He had been admitted 6 days previously for nausea, vomiting, diarrhea, fever, asthenia since the onset of dyspnea with 89% desaturation in ambient air and a dry cough. A diagnosis of gastroenteritis was made and treated without success. The appearance of abdominal distension and bloating motivated his transfer to the CTPI where the rRT-PCR was carried out positive and an X-ray of the abdomen without preparation which had demonstrated a significant aerocoly with agglutination of handle. Surgical management under general anesthesia found a clean cavity after coeliotomy, multiple intestino-intestinal, intestino-parietal and omentum-parietal adhesions. The gesture consisted of an adhesiolysis, omentectomy. The postoperative follow-up was favorable with resumption of transit on D5 postoperative. Put under the COVID-19 treatment protocol, the rRT-PCR was negative on D13, output on D14 and removal of the D19 files without postoperative complications.
文摘Objective To investigate the effect of Furongtongmai capsule on the in-stent restenosis （ISR） of superficial femoral artery after interventional operation in lower extremity Arteriosclerosis Occlusion （ASO）. Methods： A total of 110 inpatients with ASO who performed Superficial femoral artery stent implantation were randomly divided into observation group and control group, with 55 cases in each group.Both groups received Aspirin 100 mg/d and Clopidogrel 75 mg/d. The observation group was given Furongtongmai capsule on the basis of routine treatment. After continuous treatment for 6 months, the clinical efficacy, Ankle Brachial Index （ABI）, high-sensitivity C-reactive protein （Hs-CPR） and ISR were compared between the two groups. Results： At 6 months after operation, the plasma levels of Hs-CRP in the two groups were significantly lower than those in the control group （P 〈 0.05）. The ABI of treatment group was significantly higher than the control group （P 〈 0.05）. There was a statistically significant difference in ISR incidence between the treatment group and the control group 6 months after surgery （9.09% vs 27.78%, P 〈 0.05）. Conclusion： Furongtongmai Capsule can inhibit Hs-CRP in patients with ASO after femoral artery intervention, improve the ankle brachial index and reduce the incidence of ISR.
文摘Sickle cell disease is an autosomal recessive genetic disease. Vaso occlusive crisis (VOC) is frequently seen in such patients. Painful VOC is usually recurrent, of variable severity due to many factors and its management poses important challenge in the clinical practice. Few patients do not respond to standard therapies and continue to suffer severe pain for prolonged period or land to serious life threatening situation. The red cell exchange by aphaeresis is presumed to be one efficient alternative in this situation which can reduce the level of HbS below 40% - 50%. However, it is costly and not available everywhere. Both circumstances are common in our state where incidence of sickle cell disease is quite high. In such situations simple red cell exchange i.e. removing 1 unit (350 ml) of blood manually (by phlebotomy) and replacement with one unit normal red cell is effective. All of our four cases of SCA with severe acute VOC, are not responding to standard therapy but responded efficiently to this simple red cell exchange transfusion. Our present observation may pave the way of one simple, affordable, and effective measure to reduce the pain of severe acute VOC not responding to standard therapy. Moderate reduction of HbS by 8% - 14% by simple red cell exchange transfusion was associated with relief of pain of acute VOC;a new observation was reported in all our 4 cases which need to be validated by larger controlled studies.
文摘Severe thermal burns usually result in complex facial problems such as contracture and formation of hyper/hypopigmentation,contracture,hypertrophic scars or deformity,with patients often requiring reconstructive surgery.Therefore,seeking a superior and reliable burn therapy remains a great challenge for plastic and burn surgeons.However,the optimal treatment of thermal injuries remains controversial.In the 1960s,a new therapeutic concept,that sterile polyethylene film might be used as a type of moist occlusive dressing,was successively proposed.Below we present a hypothesis that combined utilization of sterile polyethylene film and burn cream may be a novel and superior therapeutic approach for thermal burns.To distinguish this method from traditional moist burn therapy,this new therapy we proposed is named modified moist occlusive burn therapy(MMOBT).

文摘BACKGROUND Convulsive-like movements are rare in basilar artery occlusive cerebral infarction(BAOCI).These manifestations may easily be mistaken for epileptic seizures caused by compromised anterior circulation or by cortical lesions.Delayed diagnosis of this condition affects its subsequent treatment and prognosis.Therefore,it is critical to recognize this type of phenomenon in the early stage.CASE SUMMARY A 55-year-old male patient presented with unconsciousness,rigidity,and a paroxysmal twitch in both lower limbs.These conditions lasted for nearly 2 h and resembled status epilepticus.After the initial conditions subsided,hemiplegia occurred and then subsided rapidly.The family refused thrombolytic therapy because the symptoms were similar to Todd paralysis after epilepsy.However,magnetic resonance imaging showed left pontine infarction.No abnormality was observed in a video electroencephalogram during the interictal period.Digital subtraction angiography revealed that the basilar artery was occluded and that the posterior communicating arteries were patent.Fortunately,the patient received a good prognosis after antiplatelet therapy,lipid regulation,balloon dilatation of the basilar artery,and rehabilitation.CONCLUSION Convulsive-like movements may be an early sign of basilar artery occlusive brainstem infarction.It is important to identify this phenomenon in a timely manner.
文摘Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb.Endovascular procedures are currently preferred for these patients.We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb.The patient had history of left femoral popliteal bypass surgery,femoral thromboendarterectomy and patch angioplasty of the same limb 2 years ago.Doppler sonography and magnetic resonance angiography revealed an occlusion of the left superficial femoral artery(SFA) and popliteal artery and of all three infra-popliteal arteries.Due to severe comorbidities,the patient was scheduled for a digital subtraction angiography.An antegrade approach was first attempted,however the occlusion could not be passed.After revision of the angiography acquisition,a stent was identified at the level of the mid SFA,which was subsequently directly punctured,facilitating the retrograde crossing of the occlusion.Thereafter,balloon angioplasty was performed in the SFA,popliteal artery and posterior tibial artery.The result was considered suboptimal,but due to the large amount of contrast agent used,a second angiography was planned in 4 wk.In the second session,drug coated balloons were used to optimize treatment of the SFA,combined with recanalization of the left fibular artery,to optimize outflow.The post-procedural course was uneventful.Ischemic pain resolved completely after the procedure and at 8 wk of follow-up and the foot ulceration completely healed.
文摘BACKGROUND Systemic amyloidosis in which multiple systems can be involved has become a common clinical disease.When the liver is affected,symptoms such as abdominal distension,fatigue,edema,liver,and jaundice could appear.To date,hepatic amyloidosis combined with hepatic venular occlusive disease and Budd-Chiari syndrome has not been reported.CASE SUMMARY A 54-year-old female patient was admitted to the Beijing Shijitan Hospital with hepatic amyloidosis leading to hepatic venular occlusion and Budd-Chiari syndrome in 2018.The patient underwent surgery 1 mo previously for liver rupture and hemorrhage after Budd-Chiari syndrome was diagnosed.She was diagnosed with hepatic venular occlusion,liver amyloidosis,and Budd-Chiari syndrome(i.e.extensive hepatic vein occlusion).Transjugular intrahepatic portosystem shunt was performed.After the treatment,the clinical symptoms improved markedly with increase in urine volume.CONCLUSION Hepatic amyloidosis with hepatic venous occlusion and Budd-Chiari syndrome is relatively rare clinically,and transjugular intrahepatic portosystem shunt is an effective treatment for this disease.

文摘Objective： To explore the efficacy of interventional therapy for chronic atherosclerotic occlusive disease of the lower extremity. Methods： Fifty-six cases of simple atherosclerotic occlusive disease of lower extremity were divided into 3 types according to the location of occhision, including 17 cases of abdominal aorta-iliac artery, 18 cases of iliac-femoral artery, and 21 cases of inferior popliteal artery. Catheter and guide wire combined with blunt dissection and subtle banding were used to dredge the occluded vessels, and stents were implanted when interlayer appeared. Results： After the treatment, 46 cases of occlusion were dredged （82.1%）, 6 cases remained occluded with the same symptoms （10.7%）, and 4 cases had severer symptoms （7.1%）. Among the 46 successful cases, there were 16 cases of abdominal aorta-iliac artery （94.1%）, 16 cases of iliac-femoral artery （88.9%） and 14 cases of inferior popliteal artery, artery （66.6%）. There was no statistical difference between the abdominal aorta-iliac artery cases and iliac-femoral artery cases （P〉0.05）, but there was statistical difference between these two types and the inferior popliteal artery cases （P〈0.05）. In the successful cases, 9 cases of abdominal aorta-iliac artery （52.9%）, 10 cases of iliac-femoral artery （55.5%） and 10 cases of inferior popliteal artery （33.3%） had 5-10 cm of occlusion, with no statistical difference between the first two types （P〉0.05）, but with statistical difference between the first two types and the third type （P〈0.05）. Compared with the 14 dredged cases （71.4%）, the 7 cases （33.3%） of inferior popliteal artery cases had richer compensatory circulation （P〈0.05）. Conclusion： It＇s safe and effective to treat simple atherosclerotic occlusive disease of the lower extremity with interventional therapy. The location and length of occlusion and the abundance of compensatory circulation had effect on the therapy.
文摘Objective: To evaluate the therapeutic effects of 0. 014' Choice PTTM wire in chronic total occlusion angioplasty. Methods: Balloon angioplasty was attempted in 25 arteries with chronic total occlusion, with the mean time of occlusion of 17±13 months (ranging from 2 to 84 months) and mean length of 14±6 mm (ranging from 5 to 25 mm). The morphology of the lesions included bridging collaterals (4 cases), calcification (3 cases) and major side branch at the lesion (4 cases) . Choice PT?wire was used electively in all the cases. Results: Lesion was crossed successfully in 92% (23/25) cases, without incidences of dissection of the coronary artery with subintimal entry. Balloon angioplasy and stenting (n = 21) were performed with good immediate angiograghic results. Acute myocardial infarction or death occurred in none of the patients. Conclusion Successful recanalization of chronic coronary total occlusions using Choice PTTM wire can be achieved with good safety.
文摘Objective: to study and analyze the value of computer body layer scanning angiography (CTA) imaging used in lower extremity vascular occlusion lesions. Methods: 30 patients with suspected lower limb vascular occlusive disease admitted to our hospital from May 2021 to January 2022 were included. The examinations received in the hospital included CTA imaging and digital subtraction angiography. The later examination results were the gold standard to evaluate the diagnostic efficacy of CTA imaging in lower limb vascular occlusive disease. Results: in this group, 27 suspected cases of lower extremity vascular diseases were confirmed by digital subtraction angiography, including 7 cases of lower extremity vascular occlusion, 20 cases of lower extremity vascular stenosis (8 cases of severe, 8 cases of moderate, 4 cases of mild), 26 cases of lower extremity vascular diseases diagnosed by CTA, 7 cases of lower extremity vascular occlusion, 19 cases of lower extremity vascular stenosis (7 cases of severe, 8 cases of moderate, 4 cases of mild). There was no statistical difference in the detection rate of disease types between the two examination methods (P > 0.05). With reference to digital subtraction angiography, the coincidence rate, specificity and sensitivity of CTA imaging in the diagnosis of lower limb vascular occlusive diseases were 96.67%, 100.00% and 96.30% respectively. Conclusion: the sensitivity and specificity of CTA in the diagnosis of lower extremity vascular occlusive disease are both high.
