Methods: 64 patients with refractory postpartum hemorrhage in our department from February 2018 to October 2020 were taken as observation objects and were divided into Group 1 and Group 2. Bakri uterine tamponade balloon catheter was used for treatment and uterine tamponade was used for treatment. The therapeutic effect of the two groups was compared. Results: (1) The effective rates of Group 1 and Group 2 were 93.75% and 75.00% respectively (χ2 = 21.083, P = 0.000). (2) In the comparison of treatment time and hospitalization time between Group 1 and Group 2, Group 1 is 16.31±2.53 (min), 4.11±0.87 (d), Group 2 is 38.64±4.74(min), 7.32±1.09 (d), (t = 7.775,P = 0.000), respectively. The results are different. Conclusion: Bakri uterine tamponade balloon catheter is effective in the treatment of refractory postpartum hemorrhage and this method is worthy of clinical promotion.展开更多

METHODS:We retrospectively studied 7 patients who underwent pericardiocentesis with intrapericardial cisplatin instillation for malignant pericardial effusion resulting from esophageal cancer.After pericardiocentesis,we performed catheterization of the pericardial space under ultrasonogram guidance.Malignant etiology of the pericardial fluid was confirmed by cytological examination.Subsequently,cisplatin(10 mg in 20 mL normal saline) was instilled into the pericardial space. RESULTS:The mean total volume of the aspirated effusion fluid was 782±264 mL(range,400-1200 mL) . The drainage catheter was successfully removed in all patients,and the mean duration of pericardial drainagewas 7.7±2.7 d(range,5-13 d) .No fluid reaccumulation was observed.Mean survival time was 120±71 d(range,68-268 d) . CONCLUSION:Pericardiocentesis along with catheter drainage appears to be a safe and effective for pericardial malignant effusion and tamponade,and cisplatin instillation prevents recurrence.展开更多

We recorded perioperative factors with the potential to influence functional outcome including duration from the injury to intervention; causes for ocular trauma; open globe or closed globe injury; grade of vitreous hemorrhage; grade of endophthalmitis; grade of retinal detachment; size and location of intraocular foreign body (IOFB); extent and position of retinal defect; grade of proliferative vitreoretinopathy (PVR); type of surgery; perioperative complications and tamponade agent. The follow-up time was from 3 to 18 months, and the mean time was 12 months.RESULTS: After a mean follow-up period of 12 months (3-18 months) 10.53% (2/19) of eyes had visual acuity of between 20/60 and 20/400, 52.63% (10/19) had visual acuity less than 20/400 but more than NLP, and 36.84% (7/19) remained NLP. Visual acuity was improved from NLP to light perception (LP) or better in 63.16% (12/19) of eyes and the rate of complete retinal reattachment was 73.68% (14/19). Good visual acuity all resulted from those patients of blunt trauma with intact eyewall (closed globe injury). The perioperative factors of poor visual acuity prognosis included delayed intervention; open globe injury; endophthalmitis; severe retinal detachment; large IOFB; macular defect; a wide range of retinal defects andsevere PVR.CONCLUSION: The main reasons of NLP after ocular trauma are severe vitreous hemorrhage opacity; refractive media opacity; retinal detachment; retinal and uveal damages and defects, especially defects of the macula; PVR and endophthalmitis. NLP after ocular trauma in some cases does not mean permanent vision loss. Early intervention of vitrectomy combined with silicone oil tamponade and achieving retinal reattachment of the remaining retina, may make the severely traumatized eyes regain the VA of LP or better.展开更多

METHODS： Of 25 consecutive patients（25 eyes） with fresh primary RRD and causative retinal break and vitreous traction were presented. All the patients underwent PPV with air tamponade. Visual acuity（VA） was examined postoperatively and images were captured by ultrawidefield scanning laser ophthalmoscope system（Optos）. RESULTS： Initial reattachment was achieved in 25 cases（100%）. The air volume was 〉60% on the postoperative day（POD） 1. The ultra-widefield images showed that the retina was reattached in all air-filled eyes postoperatively. The retinal break and laser burns in the superior were detected in 22 of 25 eyes（88%）. A missed retinal hole was found under intravitreal air bubble in 1 case（4%）. The air volume was range from 40% to 60% on POD 3. A doublelayered image was seen in 25 of 25 eyes with intravitreal gas. Retinal breaks and laser burns around were seen in the intravitreal air. On POD 7, small bubble without effect was seen in 6 cases（24%） and bubble was completely disappeared in 4 cases（16%）. Small oval bubble in the superior area was observed in 15 cases（60%）. There were no missed and new retinal breaks and no retinal detachment in all cases on the POD 14 and 1 mo and last follow-up. Air disappeared completely on a mean of 9.84 d postoperatively. The mean final postoperative bestcorrected visual acuity（BCVA） was 0.35 log MAR. Mean final postoperative BCVA improved significantly relative to mean preoperative（P〈0.05）. Final VA of 0.3 log MAR or better was seen in 13 eyes. CONCLUSION： PPV with air tamponade is an effective management for fresh RRD with superior retinal breaks. The ultra-widefield fundus imaging can detect postoperative retinal breaks in air-filled eyes. It would be a useful facility for follow-up after PPV with air tamponade. Facedown position and acquired visual rehabilitation may be shorten.展开更多

Methods: Retrospective review of 58 women who underwent balloon tamponade for severe PPH, during a period of 5 years and 10 months, at Russells Hall Hospital, a busy district general hospital in UK. Clinical success was defined as control of bleeding without need for further intervention. Results: Fifty-eight women (mean age, 30 years;range, 18 - 42) underwent balloon tamponade, of which twenty seven (46.5%) women delivered vaginally and 31 (53.5%) women were delivered by cesarean section. Uterine atony was the main cause of PPH (31 cases). Balloon tamponade was used prophylactically in 11 high risk women in anticipation of potential PPH. Rusch balloon was used in 48 cases and Bakri balloon in 10 cases. Clinical success rate of balloon tamponade was 87.2%. Three patients in this study required hysterectomy. Conclusion: Balloon tamponade is an effective means of controlling severe PPH with success rates of around 87%. There should also be a low threshold for prophylactic use of balloon tamponade in women at high risk of PPH, considering its ease of use, low complication rate and ability to maintain reproductive ability.展开更多

METHODS： A search of the MEDLINE database revealed 16 cases of pericarditis carcinomatosa （PC） originating from GC reported in the literature between 1982 and 2005. Additional detailed data were obtained from the authors of these studies for subsequent clinicopathological investigation. We have also described about a case study from our own clinic. RESULTS： The mean age of cases with pericarditis carcinomatosa originating from GC was 54 years. Females were diagnosed at a younger age （46.3 years） compared to males （58 years）. The mean survival period afer diagnosis was 4.5 mo. No statistical differences in the length of survival time were found between different therapeutic modalities, such as drainage, and local and/or systemic chemotherapy after drainage. However, three cases who underwent systemic chemotherapy survived for more than 10 mo. Cases that developed metachronous cardiac tamponade for more than 2 years afer the diagnosis of GC generally survived for a longer period of time, although this was not statistically significant. Multivariate analysis revealed that low levels of carcinoembryonic antigen （CEA）, and CEA and/or cancer antigen 19-9 （CA 19-9） were associated with longer survival. CONCLUSION： Cases with low levels of CEA, and CEA and/or CA 19-9 should undergo systemic chemotherapy with or without local chemotherapy afer drainage.展开更多

METHODS： We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher＇s exact test and unpaired two-tailed t-test. RESULTS： One hundred and six patients（76.2%） had undergone silicone oil removal at the time of review with 96 patients（90.6%） showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity（BCVA）. Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade（P=0.0001, 〈0.0001 respectively）. CONCLUSION： Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.展开更多

A 76-year-old man with previous admissions due to right heart failure and previous history of atrial fibrillation under acenocumarol, was admitted to our hospital for new onset of symptoms, characterized by progressive dyspnoea and peripheral edema. Physical examination revealed signs of congestive heart failure and a continuous murmur loudest along the lower sternal border. X-Ray showed cardiomegaly due to right chambers dilatation. Transthoracic echocardiography showed right chambers pressure and volume overload, with right ventricular enlargement and dysfunction, tricuspid annulus dilatation and severe tricuspid regurgitation. Cardiac catheterization showed significant elevation of right atrial pressure, as well as significant step-up of oxygen saturation in this chamber. Coronary angiography revealed the presence of a large fistula between the circumflex coronary artery (CCA) and coronary sinus (CS), with severe dilation of the CCA (maximum diameter20 mm). An Amplatzer? PDA was implanted in a distal elbow of the fistula with initailly good results. Anticoagulant therapy was then reinitiated, and a few days later, the patient developed clinical worsening of heart failure and dyspnoea. Echocardiogram showed significant pericardial effusion. Pleuropericardial window was then made draining a500 cm3 of bloody pericardial effusion. The postoperative outcome was excellent, with symptomatic relief and no signs of heart failure.展开更多

Patients are generally asymptomatic until the disease is advanced. General practitioners usually focus on the initial symptoms related to pericarditis and pericardial effusion. We report a case of signet-ring cell carcinoma of the stomach presenting as cardiac tamponade with pericarditis and pericardial effusion but without any gastrointestinal symptoms. A 49-year old woman was admitted because of progressive dyspnea and cough. Chest X-ray revealed an increased cardiothoracic ratio and a small amount of bilateral pleural effusion. Two dimensional ultrasonographic echocardiography pericardial effusions with atrial and right ventricular early diastolic collapse were found, establishing the diagnosis of cardiac tamponade. Pericardiocentesis was performed and 420 mL of bloody ?uid was taken. The patient died of respiratory failure and cardiac arrest on October 28, 2009.

文摘AIM:To investigate the effects of shortening the duration of silicone oil tamponade on retinal structure and function in patients undergoing silicone oil removal(SOR)after surgery for primary rhegmatogenous retinal detachment(RRD).METHODS:A total of 58 eligible patients were enrolled and randomly assigned to two groups based on tamponade duration:the short-term group(30-45d)and the conventional group(≥90d).Comprehensive evaluations were performed before and after SOR,including slitlamp examination,best-corrected visual acuity(BCVA)measurement,intraocular pressure(IOP)testing,optical coherence tomography(OCT),optical coherence tomography angiography(OCTA),microperimetry,electroretinography(ERG),and visual evoked potential(VEP)assessment.RESULTS:A total of 33 patients(23 males and 10 females;33 eyes)were enrolled in the short-term SO tamponade group with mean age of 52.45±9.35y,and 25 patients(15 males and 10 females;25 eyes)were enrolled in the conventional SO tamponade group with mean age of 50.80±12.06y.Compared with the conventional group,the short-term silicone oil tamponade group had a significantly lower incidence of silicone oil emulsification and cataract progression,with no significant difference in retinal reattachment success rate.Structurally,short-term tamponade was associated with increased thickness of the retinal ganglion cell layer(RGCL)in the nasal and superior macular regions and improved recovery of superficial retinal vascular density in these areas.Functionally,the shortterm group showed better BCVA and retinal sensitivity both before and 1mo after SOR;additionally,the P100 amplitude in VEP tests was significantly increased in this group.CONCLUSION:Shortening the duration of silicone oil tamponade effectively reduces damage to retinal structure and function without compromising the success rate of retinal reattachment in patients with primary RRD.
文摘BACKGROUND The use of percutaneous transcatheter edge-to-edge repair(TEER)for mitral regurgitation(MR)has increased,including an increased application to older,frailer,and higher risk patients.CASE SUMMARY A 74 year-old woman with severe MR,a left ventricular ejection fraction of 45%,and a small circumferential pericardial effusion underwent TEER of the mitral valve.After the placement of two MitraClips,the MR was assessed as mild to moderate.Within 10-20 minutes after the completion of the case,the patient was dyspneic and hypotensive despite volume resuscitation.Point-of-care ultrasound(POCUS)showed no changes in cardiac contractility,valve function,or the pericardial space.The right heart chambers appeared small with right atrial(RA)diastolic collapse.There was no evidence of venous congestion.Further exam showed a large right pleural fluid collection.Given the clinical scenario of dyspnea,hypotension,and diastolic RA collapse,low-pressure tamponade was suspected.A thoracentesis expelled 1200 mL of blood with immediate hemodynamic improvement.The patient made an uneventful recovery.CONCLUSION The application of POCUS is crucial for detecting,diagnosing,and properly managing cardiac dysfunction and procedural complications associated with TEER.While tamponade is classically associated with a pericardial effusion and vena caval plethora,their absence does not dismiss the suspicion or diagnosis of tamponade.This case highlights the value of POCUS in assessing low-pressure tamponade caused by a large,pressurized pleural effusion.Clinical suspicion,supported by POCUS findings,was confirmed by a thoracentesis that resulted in immediate hemodynamic improvement.
文摘Objective: to observe the therapeutic effect of Bakri uterine tamponade balloon catheter for refractory postpartum hemorrhage. Methods: 64 patients with refractory postpartum hemorrhage in our department from February 2018 to October 2020 were taken as observation objects and were divided into Group 1 and Group 2. Bakri uterine tamponade balloon catheter was used for treatment and uterine tamponade was used for treatment. The therapeutic effect of the two groups was compared. Results: (1) The effective rates of Group 1 and Group 2 were 93.75% and 75.00% respectively (χ2 = 21.083, P = 0.000). (2) In the comparison of treatment time and hospitalization time between Group 1 and Group 2, Group 1 is 16.31±2.53 (min), 4.11±0.87 (d), Group 2 is 38.64±4.74(min), 7.32±1.09 (d), (t = 7.775,P = 0.000), respectively. The results are different. Conclusion: Bakri uterine tamponade balloon catheter is effective in the treatment of refractory postpartum hemorrhage and this method is worthy of clinical promotion.
文摘AIM:To evaluate the role and outcome of pericardiocentesis with intrapericardial cisplatin instillation for malignant pericardial effusion resulting from esophageal cancer. METHODS:We retrospectively studied 7 patients who underwent pericardiocentesis with intrapericardial cisplatin instillation for malignant pericardial effusion resulting from esophageal cancer.After pericardiocentesis,we performed catheterization of the pericardial space under ultrasonogram guidance.Malignant etiology of the pericardial fluid was confirmed by cytological examination.Subsequently,cisplatin(10 mg in 20 mL normal saline) was instilled into the pericardial space. RESULTS:The mean total volume of the aspirated effusion fluid was 782±264 mL(range,400-1200 mL) . The drainage catheter was successfully removed in all patients,and the mean duration of pericardial drainagewas 7.7±2.7 d(range,5-13 d) .No fluid reaccumulation was observed.Mean survival time was 120±71 d(range,68-268 d) . CONCLUSION:Pericardiocentesis along with catheter drainage appears to be a safe and effective for pericardial malignant effusion and tamponade,and cisplatin instillation prevents recurrence.
文摘AIM：To evaluate the long-term safety and efficacy of vitrectomy and internal limiting membrane（ILM）peeling with or without gas tamponade for highly myopic foveoschisis.METHODS：We performed an open-label,observerblinded clinical trial of 85 patients with myopic foveoschisis between 2000 and 2012.Patients were randomly allocated to one of two groups,those who received vitrectomy and ILM peeling without gas tamponade（no-gas group）or those who with gas tamponade（gas group）and follow up at least 5y.RESULTS：Visual acuity of gas group improved from0.82±0.33 to 0.79±0.73 in 6mo,improved to 0.71±0.67 in 1y and within this range in the following 4y.Visual acuity of no-gas group improved from 0.81±0.46 to 0.78±0.66 in 6mo,improved to 0.70±0.65 in 1y.The finial visual acuity of two groups were significantly increased compared with the baseline（P〈0.05）.The visual acuity was improved in 35 of40 eyes（87.5%）in gas group and 29 of 33 eyes（87.9%）in no-gas group,while there were no significant differences between gas group and no-gas group in the visual acuity.The foveoschisis on optical coherence tomography（OCT）completely resolved in 5 of 40 eyes in 1mo,14 eyes in 6mo and 40 eyes in 1y in the gas group.While the foveoschisis completely resolved in 4 of 33 eyes in 1mo,10 eyes in 6mo and 33 eyes in 1y in the no-gas group.CONCLUSION：Vitrectomy and ILM peeling without gas tamponade appears to be as effective in the treatment of myopic foveoschisis as vitrectomy and ILM with gas tamponade.However,eyes treated with no-gas tamponade showed more rapid resolution of myopic foveoschisis.
文摘AIM: To evaluate the efficacy of surgical treatment of vitrectomy combined with silicone oil tamponade in the treatment of severely traumatized eyes with the visual acuity of no light perception (NLP).METHODS: This was a retrospective uncontrolled interventional case-series of 19 patients of severely traumatized eyes with NLP who underwent vitrectomy surgery at the Affiliated Hospital of Medical College, Qingdao University (Qingdao, China) during a 3-year period. We recorded perioperative factors with the potential to influence functional outcome including duration from the injury to intervention; causes for ocular trauma; open globe or closed globe injury; grade of vitreous hemorrhage; grade of endophthalmitis; grade of retinal detachment; size and location of intraocular foreign body (IOFB); extent and position of retinal defect; grade of proliferative vitreoretinopathy (PVR); type of surgery; perioperative complications and tamponade agent. The follow-up time was from 3 to 18 months, and the mean time was 12 months.RESULTS: After a mean follow-up period of 12 months (3-18 months) 10.53% (2/19) of eyes had visual acuity of between 20/60 and 20/400, 52.63% (10/19) had visual acuity less than 20/400 but more than NLP, and 36.84% (7/19) remained NLP. Visual acuity was improved from NLP to light perception (LP) or better in 63.16% (12/19) of eyes and the rate of complete retinal reattachment was 73.68% (14/19). Good visual acuity all resulted from those patients of blunt trauma with intact eyewall (closed globe injury). The perioperative factors of poor visual acuity prognosis included delayed intervention; open globe injury; endophthalmitis; severe retinal detachment; large IOFB; macular defect; a wide range of retinal defects andsevere PVR.CONCLUSION: The main reasons of NLP after ocular trauma are severe vitreous hemorrhage opacity; refractive media opacity; retinal detachment; retinal and uveal damages and defects, especially defects of the macula; PVR and endophthalmitis. NLP after ocular trauma in some cases does not mean permanent vision loss. Early intervention of vitrectomy combined with silicone oil tamponade and achieving retinal reattachment of the remaining retina, may make the severely traumatized eyes regain the VA of LP or better.
文摘AIM:To evaluate the safety and efficacy of Densiron 68 heavy silicone oil (HSO) tamponade for complicated retinal detachment(RD)in Chinese eyes.METHODS:Twenty-one eyes of 21 patients with complicated RD were included in this retrospective study.All patients underwent pars plana vitrectomy with an internal tamponade using Densiron 68 HSO.Anatomical and functional results and complications were evaluated,including retinal status,visual acuity(VA),intraocular pressure(IOP),intraocular inflammation,lens opacity,and HSO emulsification.RESULTS:Allthepatients were followed up for 3mo to1y(5.8±1.16mo).Retinal reattachment was achieved in 19of 21 patients(90.5%).VA improved in 18 of 21 patients(85.7%),from 1.93 logMAR(±0.48)to 1.52 logMAR(±0.45)(P=0.001).Postoperative complications included early dispersion of HSO in 7 eyes(38.8%),cataract in 10 of 18phakic eyes(55.5%),moderate postoperative inflammation reaction in 10 eyes(47.6%),and elevated IOP in 5 eyes(23.8%),all of which were controlled by medication or by surgery.CONCLUSION:Highanatomical and functional success rates can be achieved with primary vitrectomy for complicated RD by using Densiron 68 HSO;however,it should not be ignored that Densiron 68 HSO can cause some complications in the eye.
文摘BACKGROUND Peripherally inserted central catheters(PICCs)have been increasingly applied worldwide owing to many advantages.Even with these advantages,the related complications should not be ignored,especially in neonates.The available evidence about PICC-related thrombosis was manifold,but the cardiac tamponade,an emergency and life-threatening complication,has been rarely reported.Early recognized cardiac tamponade by ultrasound may reduce mortality.CASE SUMMARY A neonate weighting 2.8 kg was born at 40 wk of gestation.He was admitted to the Surgery Intensive Care Unit due to suspected congenital megacolon.A PICC line was inserted via the left antecubital fossa for the administration of total parenteral nutrition.Three days later,the patient was still on total parenteral nutrition.Cardiac tamponade caused by PICC was found on ultrasound.The patient recovered spontaneously after an emergency pericardiocentesis.CONCLUSION Proficiency in the use of point-of-care ultrasound may save the life of patients,since it enables clinicians to treat patients faster,more accurately,and in a noninvasive way at the point of care.
文摘AIM： To report the surgical result of pars plana vitrectomy（PPV） with air tamponade for rhegmatogenous retinal detachment（RRD） by ultra-widefield fundus imaging system. METHODS： Of 25 consecutive patients（25 eyes） with fresh primary RRD and causative retinal break and vitreous traction were presented. All the patients underwent PPV with air tamponade. Visual acuity（VA） was examined postoperatively and images were captured by ultrawidefield scanning laser ophthalmoscope system（Optos）. RESULTS： Initial reattachment was achieved in 25 cases（100%）. The air volume was 〉60% on the postoperative day（POD） 1. The ultra-widefield images showed that the retina was reattached in all air-filled eyes postoperatively. The retinal break and laser burns in the superior were detected in 22 of 25 eyes（88%）. A missed retinal hole was found under intravitreal air bubble in 1 case（4%）. The air volume was range from 40% to 60% on POD 3. A doublelayered image was seen in 25 of 25 eyes with intravitreal gas. Retinal breaks and laser burns around were seen in the intravitreal air. On POD 7, small bubble without effect was seen in 6 cases（24%） and bubble was completely disappeared in 4 cases（16%）. Small oval bubble in the superior area was observed in 15 cases（60%）. There were no missed and new retinal breaks and no retinal detachment in all cases on the POD 14 and 1 mo and last follow-up. Air disappeared completely on a mean of 9.84 d postoperatively. The mean final postoperative bestcorrected visual acuity（BCVA） was 0.35 log MAR. Mean final postoperative BCVA improved significantly relative to mean preoperative（P〈0.05）. Final VA of 0.3 log MAR or better was seen in 13 eyes. CONCLUSION： PPV with air tamponade is an effective management for fresh RRD with superior retinal breaks. The ultra-widefield fundus imaging can detect postoperative retinal breaks in air-filled eyes. It would be a useful facility for follow-up after PPV with air tamponade. Facedown position and acquired visual rehabilitation may be shorten.
文摘Objective: To evaluate the effectiveness of balloon tamponade in the management of postpartum hemorrhage (PPH). Methods: Retrospective review of 58 women who underwent balloon tamponade for severe PPH, during a period of 5 years and 10 months, at Russells Hall Hospital, a busy district general hospital in UK. Clinical success was defined as control of bleeding without need for further intervention. Results: Fifty-eight women (mean age, 30 years;range, 18 - 42) underwent balloon tamponade, of which twenty seven (46.5%) women delivered vaginally and 31 (53.5%) women were delivered by cesarean section. Uterine atony was the main cause of PPH (31 cases). Balloon tamponade was used prophylactically in 11 high risk women in anticipation of potential PPH. Rusch balloon was used in 48 cases and Bakri balloon in 10 cases. Clinical success rate of balloon tamponade was 87.2%. Three patients in this study required hysterectomy. Conclusion: Balloon tamponade is an effective means of controlling severe PPH with success rates of around 87%. There should also be a low threshold for prophylactic use of balloon tamponade in women at high risk of PPH, considering its ease of use, low complication rate and ability to maintain reproductive ability.

文摘AIM： To review the cases reported in the literature, examined their clinicopathological features, and evaluated the efficacy of different therapeutic modalities for this rare condition. METHODS： A search of the MEDLINE database revealed 16 cases of pericarditis carcinomatosa （PC） originating from GC reported in the literature between 1982 and 2005. Additional detailed data were obtained from the authors of these studies for subsequent clinicopathological investigation. We have also described about a case study from our own clinic. RESULTS： The mean age of cases with pericarditis carcinomatosa originating from GC was 54 years. Females were diagnosed at a younger age （46.3 years） compared to males （58 years）. The mean survival period afer diagnosis was 4.5 mo. No statistical differences in the length of survival time were found between different therapeutic modalities, such as drainage, and local and/or systemic chemotherapy after drainage. However, three cases who underwent systemic chemotherapy survived for more than 10 mo. Cases that developed metachronous cardiac tamponade for more than 2 years afer the diagnosis of GC generally survived for a longer period of time, although this was not statistically significant. Multivariate analysis revealed that low levels of carcinoembryonic antigen （CEA）, and CEA and/or cancer antigen 19-9 （CA 19-9） were associated with longer survival. CONCLUSION： Cases with low levels of CEA, and CEA and/or CA 19-9 should undergo systemic chemotherapy with or without local chemotherapy afer drainage.

文摘Percutaneous left atrial appendage(LAA)occlusion evolved as an alternative treatment to the patients who are contraindicated or cannot tolerate oral anticoagulants with nonvalvular atrial fibrillation(AF)at risk of stroke or systemic embolism.[1]Abnormal hemodynamic changes in elder atrial septal defect(ASD)patients cause remodeling of the left atrium,which eventually leads to right heart failure.[2]As the ASDs elderly are associated with a higher incidence of AF,simultaneous transcatheter ASD and LAA closure has become a new effective therapeutic strategy.However,only a limited number of articles involving cardiac tamponade complications have been published in the literature.What’s more,previous studies involving early hemodynamically irrelevant pericardial effusion after the procedure attribute to multiple repositioning attempts of LAA occluder or delivery sheath injured the atrial wall.
文摘AIM:To evaluate outcomes and determine factors influencing the outcomes of vitrectomy with silicone oil(SO)endotamponade for the management of rhegmatogenous retinal detachment(RRD)complicated by advanced proliferative vitreoretinopathy(PVR).METHODS:This is a retrospective,interventional case series of eyes with PVR grade C associated RRD with or without prior surgery that underwent vitreoretinal surgery and SO tamponade.Eyes with a minimum follow-up of 6mo after SO extraction were included.Eyes were classified into three PVR subgroups according to severity and extension of proliferation.The influence of several preoperative,intraoperative and postoperative factors upon the functional and anatomical outcomes was assessed using multivariate logistic regression analysis.RESULTS:A hundred and one eyes of 101 patients that met the inclusion criteria were studied.Seventy-five of 101 eyes(74.3%)had successful retinal reattachment after one operation.Increased aqueous cell and flare at the first week exam had a statistically significant association with redetachment,recurrent membrane proliferation and keratopathy.Visual acuity improvement was significantly associated with faint postoperative aqueous inflammation values,primary vitrectomy and PVR outside of the posterior pole.CONCLUSION:Although encouraging anatomical and functional outcomes are achieved after vitrectomy and SO tamponade in eyes with RRD complicated by PVR,an increase in aqueous flare or cells at the first week follow-up is most likely to result in postoperative late complications.Primary vitrectomy,PVR associated with minimal posterior pole extension and absent to mild postoperative aqueous inflammation are associated with improved post-operative final visual acuity.
文摘The coxsackievirus is well known for its vastly differing clinical presentations.Patients with coxsackievirus usually present with a viral prodrome which can then progress to the cardiac symptoms of chest pain and/or palpitations.Most patients improve quickly with simply supportive care and nonsteroidal anti-inflammatory medications.
文摘BACKGROUND Acute severe variceal bleeding(AVB)refractory to medical and endoscopic therapy is infrequent but associated with high mortality.Historical cohort studies from 1970-1980s no longer represent the current population as balloon tamponade is no longer first-line therapy for variceal bleeding;treatments including vasoactive therapies,intravenous antibiotics,endoscopic variceal band ligation are routinely used,and there is improved access to definitive treatments including transjugular intrahepatic portosystemic shunts.However,only a few studies from the current era exist to describe the practice of balloon tamponade,its outcomes,and predictors with a requirement for further updated information.AIM To describe current management of AVB requiring balloon tamponade and identify the outcomes and predictors of mortality,re-bleeding and complications.METHODS A retrospective multi-centre cohort study of 80 adult patients across two large tertiary health networks from 2008 to 2019 in Australia who underwent balloon tamponade using a Sengstaken-Blakemore tube(SBT)were included for analysis.Patients were identified using coding for balloon tamponade.The primary outcome of this study was all-cause mortality at 6 wk after the index AVB.Secondary outcomes included re-bleeding during hospitalisation and complications of balloon tamponade.Predictors of these outcomes were determined using univariate and multivariate binomial regression.RESULTS The all-cause mortality rates during admission and at 6-,26-and 52 wk were 48.8%,51.2%and 53.8%,respectively.Primary haemostasis was achieved in 91.3%and re-bleeding during hospitalisation occurred in 34.2%.Independent predictors of 6 wk mortality on multivariate analysis included the Model for Endstage Liver disease(MELD)score(OR 1.21,95%CI 1.06-1.41,P=0.006),advanced hepatocellular carcinoma(OR 11.51,95%CI 1.61-82.20,P=0.015)and re-bleeding(OR 13.06,95%CI 3.06-55.71,P<0.001).There were no relevant predictors of re-bleeding but a large proportion in which this occurred did not survive 6 wk(76.0%vs 24%).Although mucosal trauma was the most common documented complication after SBT insertion(89.5%),serious complications from SBT insertion were uncommon(6.3%)and included 1 patient who died from oesophageal perforation.CONCLUSION In refractory AVB,balloon tamponade salvage therapy is associated with high rates of primary haemostasis with low rates of serious complications.Re-bleeding and mortality however,remain high.
文摘AIM： To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. METHODS： We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher＇s exact test and unpaired two-tailed t-test. RESULTS： One hundred and six patients（76.2%） had undergone silicone oil removal at the time of review with 96 patients（90.6%） showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity（BCVA）. Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade（P=0.0001, 〈0.0001 respectively）. CONCLUSION： Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.
文摘We present the case of an unusual complication after percutaneous closure of a giant coronary artery fis-tula. A 76-year-old man with previous admissions due to right heart failure and previous history of atrial fibrillation under acenocumarol, was admitted to our hospital for new onset of symptoms, characterized by progressive dyspnoea and peripheral edema. Physical examination revealed signs of congestive heart failure and a continuous murmur loudest along the lower sternal border. X-Ray showed cardiomegaly due to right chambers dilatation. Transthoracic echocardiography showed right chambers pressure and volume overload, with right ventricular enlargement and dysfunction, tricuspid annulus dilatation and severe tricuspid regurgitation. Cardiac catheterization showed significant elevation of right atrial pressure, as well as significant step-up of oxygen saturation in this chamber. Coronary angiography revealed the presence of a large fistula between the circumflex coronary artery (CCA) and coronary sinus (CS), with severe dilation of the CCA (maximum diameter20 mm). An Amplatzer? PDA was implanted in a distal elbow of the fistula with initailly good results. Anticoagulant therapy was then reinitiated, and a few days later, the patient developed clinical worsening of heart failure and dyspnoea. Echocardiogram showed significant pericardial effusion. Pleuropericardial window was then made draining a500 cm3 of bloody pericardial effusion. The postoperative outcome was excellent, with symptomatic relief and no signs of heart failure.

文摘AIM:To evaluate the efficacy and safety of perfluoro-n-octane(PFO)for ophthalmic surgery versus F-Octane as an intraoperative tamponade in pars plana vitrectomy(PPV)in management of retinal detachment.METHODS:This multicenter,prospective,randomized,double-masked,parallel-controlled,non-inferiority trial was conducted in three ophthalmology clinical centers in China.Patients with retinal detachment,who were eligible for PPV were consecutively enrolled.Participants were assigned to PFO for ophthalmic surgery or F-Octane for intraocular tamponade in a 1:1 ratio.Best-corrected visual acuity(BCVA),intraocular pressure(IOP)measurement,and dilated fundus examination were performed preoperatively and at 1,7±1,28±3d postoperatively.The primary outcome was complete retinal reattachment rate at postoperative day one.The non-inferiority margin was set at 9.8%.The secondary outcomes included intraoperative retinal reattachment rate,and mean changes in IOP and BCVA from baseline to 1,7±1,28±3d postoperatively,respectively.Safety analyses were presented for all randomly assigned participates in this study.RESULTS:Totally 124 eligible patients completed the study between Mar.14,2016 and Jun.7,2017.Sixty of them were randomly assigned to the PFO for ophthalmic surgery group,and 64 were assigned to the F-Octane group.Baseline characteristics were comparable between the two groups.Both groups achieved 100%retinal reattachment at postoperative day one(difference 0,95%CI:-6.21%to 5.75%,P=1).The pre-defined noninferiority criterion was met.No significant difference was observed in intraoperative retinal reattachment rate(difference 1.77%,P=0.61),mean changes in IOP(difference 0.36,-0.09,2.22 mm Hg at 1,7±1,28±3d postoperatively,with all P>0.05)and BCVA(difference 0.04,-0.02,0.06 logMAR at 1,7±1,28±3d postoperatively,all P>0.05)between the two groups.No apparent adverse events related to the utilization of PFO were reported.CONCLUSION:In patients with retinal detachment undergoing PPV,PFO for ophthalmic surgery is non-inferior to F-Octane as an intraocular tamponade,and both are safe and well-tolerated.
文摘Primary gastric signet ring cell carcinoma presenting as cardiac tamponade is difficult to diagnosis early. Patients are generally asymptomatic until the disease is advanced. General practitioners usually focus on the initial symptoms related to pericarditis and pericardial effusion. We report a case of signet-ring cell carcinoma of the stomach presenting as cardiac tamponade with pericarditis and pericardial effusion but without any gastrointestinal symptoms. A 49-year old woman was admitted because of progressive dyspnea and cough. Chest X-ray revealed an increased cardiothoracic ratio and a small amount of bilateral pleural effusion. Two dimensional ultrasonographic echocardiography pericardial effusions with atrial and right ventricular early diastolic collapse were found, establishing the diagnosis of cardiac tamponade. Pericardiocentesis was performed and 420 mL of bloody ?uid was taken. The patient died of respiratory failure and cardiac arrest on October 28, 2009. Post-mortem examination revealed diffuse gastric mucosa erosion and edema with stomach mucosa incrassation in the greater curvature. The primary lesion was histopathologically diagnosed as signet-ring cell carcinoma of the stomach.
