When acute fluid collection persists for 4 - 6 weeks and is encapsulated by a fibrous wall, it is classified as a pancreatic pseudocyst. While PPC is generally asymptomatic in many patients, it can manifest with persistent abdominal pain, dyspepsia, intra-cystic infection, and potentially lead to gastrointestinal obstruction in some cases. Although smaller PPCs may resolve spontaneously, larger PPCs tend to be refractory to absorption and often necessitate surgical intervention to prevent complications such as intracystic hemorrhage. Objective: To explore the efficacy of percutaneous catheterization with negative pressure in the treatment of large pancreatic pseudocysts. Methods: The cases of large pancreatic pseudocysts treated in our hospital from 2004 to 2022 were retrospectively collected, and the general condition, operation time, drainage time, feeding time, postoperative complications, hospital stay, cost and follow-up of the patients were analyzed. Results: A total of 132 patients with large pancreatic pseudocysts were collected. The average operation time was 32.4 ± 2.1 min;The retention time of the drainage tube was 30 ± 1.8 days in the percutaneous negative pressure drainage group;The postoperative feeding time was no fasting after local anesthesia drainage;Postoperative complications (bleeding, infection, pancreatic leakage, recurrence, anastomotic leakage, etc.): Two of the 132 patients had recurrent cysts, which were cured by re-puncture and negative pressure drainage. The length of hospital stay was 6 ± 1.1 days;The cost was 11,200 ± 1300 yuan;Follow-up: The follow-up time ranged from 1 to 3 years, and the patients had no discomfort. Conclusion: Percutaneous catheterization and negative pressure drainage can effectively treat large pancreatic pseudocysts. Compared with other treatment methods, it is simple and effective, the postoperative recovery of patients is faster, the physical damage is less, the hospital stay is shorter, and the cost is lower.展开更多

文摘OBJECTIVE To evaluate the safety and effectiveness of robot-assisted percutaneous coronary intervention(R-PCI)compared to traditional manual percutaneous coronary intervention(M-PCI).METHODS This prospective,multicenter,randomized controlled,non-inferior clinical trial enrolled patients with coronary heart disease who met the inclusion criteria and had indications for elective percutaneous coronary intervention.Participants were randomly assigned to either the R-PCI group or the M-PCI group.Primary endpoints were clinical and technical success rates.Clinical success was defined as visually estimated residual post-percutaneous coronary intervention stenosis<30% with no 30-day major adverse cardiac events.Technical success in the R-PCI group was defined as successful completion of percutaneous coronary intervention using the ETcath200 robot-assisted system,without conversion to M-PCI in the event of a guidewire or balloon/stent catheter that was unable to cross the vessel or was poorly supported by the catheter.Secondary endpoints included total procedure time,percutaneous coronary intervention procedure time,fluoroscopy time,contrast volume,operator radiation exposure,air kerma,and dose-area product.RESULTS The trial enrolled 152 patients(R-PCI:73 patients,M-PCI:79 patients).Lesions were predominantly B2/C type(73.6%).Both groups achieved 100% clinical success rate.No major adverse cardiac events occurred during the 30-day follow-up.The R-PCI group had a technical success rate of 100%.The R-PCI group had longer total procedure and fluoroscopy times,but lower operator radiation exposure.The percutaneous coronary intervention procedure time,contrast volume,air kerma,and dose-area product were similar between the two groups.CONCLUSIONS For certain complex lesions,performing percutaneous coronary intervention using the ETcath200 robot-assisted system is safe and effective and does not result in conversion to M-PCI.

文摘BACKGROUND Acute myocardial infarction(AMI)is a major cause of mortality worldwide.The stress hyperglycemia ratio(SHR),which integrates glucose and glycated hemoglobin A1c levels,better reflects acute metabolic stress.This study assessed the SHR and longterm prognosis of patients with AMI.METHODS This study was a post-hoc analysis based on the prospective,multicenter OPTIMAL registry(http://www.clinicaltrials.gov,NCT number:NCT03084991).A total of 3384 consecutive patients who underwent percutaneous coronary intervention(PCI)at Department of Cardiology,The 2nd Affiliated Hospital of Harbin Medical University,Harbin,China were included in the present analysis after exclusions.Patients were stratified into quartiles according to the SHR.The primary endpoint was cardiovascular death,with all-cause death and major adverse cardiovascular events as secondary endpoints.The median follow-up duration was 24.1 months,with a completion rate of 99.5%.RESULTS Kaplan-Meier survival curves showed progressively worse survival across SHR quartiles(log-rank P<0.001),with patients in Q4(SHR≥1.34)experiencing the highest risk.Multivariate Cox regression analysis confirmed that the SHR was an independent predictor of cardiovascular death[hazard ratio(HR)=1.56],all-cause death(HR=1.48),and major adverse cardiovascular events(HR=1.34)for Q4(SHR≥1.34)versus Q2(SHR:0.93–1.11).Restricted cubic spline analysis revealed a J-shaped association between SHR and outcomes,with the lowest risk observed at an SHR of approximately 1.0.CONCLUSIONS The SHR is an independent predictor of long-term adverse outcomes in patients with AMI undergoing PCI,supporting its use for early risk stratification and glycemic management.
文摘Background Percutaneous coronary intervention(PCI)is a widely utilized revascularization technique for coronary artery disease(CAD).While clinical and biomarker-based prognostic tools are standard for predicting outcomes,there is growing interest in sarcopenia as a marker of frailty and its potential role in long-term prognosis.The prognostic value of the psoas muscle index(PMI),a sarcopenia metric,remains underexplored in PCI populations regarding long term survival.Methods This single-center retrospective cohort study evaluated 177 patients undergoing PCI from 2015 to 2019.PMI was calculated from computed tomography(CT)imaging at the L3 vertebral level using the formula:(left psoas area+right psoas area)/height2 and expressed in cm^(2)/m^(2).Sarcopenia was defined as the lowest sex-specific PMI quartile.Primary outcomes included 5-year all-cause mortality and 3-point major adverse cardiovascular events(MACE:non-fatal myocardial infarction,ischemic stroke,and cardiac death).Binary linear regression and Cox proportional hazards models were utilized to determine associations between PMI and outcomes Results Sarcopenic patients exhibited significantly higher 5-year all-cause mortality compared to non-sarcopenic counterparts(64.4%vs.35.6%,P<0.001),while no significant difference was observed in 3-point MACE incidence(55.6%vs.51.4%,P=0.520).Sarcopenia was independently associated with all-cause mortality on binary logistic regression(OR=3.49;95%CI:1.69–7.19;P=0.0007),but not MACE(OR=1.00;95%CI:0.50–1.98;P=0.99).In a multivariable Cox regression model,sarcopenia was associated with increased hazard of mortality(HR=1.60;95%CI:0.96–2.66;P=0.071),though this did not reach statistical significance.Kaplan-Meier analysis demonstrated significantly reduced survival among sarcopenic patients(χ^(2)=6.13,P=0.0133).Conclusions PMI is a significant independent predictor of 5-year all-cause mortality in PCI patients,underscoring the prognostic importance of assessing skeletal muscle mass in this population.

文摘BACKGROUND Antithrombotic strategies after percutaneous coronary interventions(PCI)in elderly patients on oral anticoagulant therapy(OAT)are debated due to the balance between ischemic and bleeding risks.Recent guidelines recommend early transitioning from triple antithrombotic therapy to dual antithrombotic therapy,but there are limited data on elderly patients.METHODS We performed a post-hoc age-specific analysis of the PERSEO Registry population aimed to compare clinical features,therapeutic strategies,and outcomes of individuals aged≥80 years and<80 years who were on OAT and underwent PCI with stent.The primary endpoint was net adverse clinical events at 1-year follow-up.Secondary endpoints included major adverse cardiac and cerebral events(MACCE),major bleeding[Bleeding Academic Research Consortium(BARC)type 3–5],and clinically relevant bleeding(BARC type 2-5).RESULTS Among the 1234 patients enrolled,31%of patients were aged≥80 years(84±3 years,76% males).Compared to younger patients,elderly patients had higher rates of comorbidities such as hypertension,anaemia or chronic kidney disease,and atrial fibrillation was the leading indication for OAT.Elderly patients were more often discharged on dual antithrombotic therapy(23%)compared to younger patients(13%)(P<0.0001).They experienced higher net adverse clinical events(38%vs.21%,P<0.001),MACCE(24%vs.12%,P<0.001),as well as higher bleeding rates.Specifically,rates of major bleeding(9%vs.6%,P=0.026),and clinically relevant bleeding(21%vs.12%,P<0.001)were significantly higher in elderly patients.CONCLUSIONS Elderly patients on OAT undergoing PCI are a particular frail population with higher risk of MACCE and bleeding compared to younger patients despite a less aggressive antithrombotic therapy.
文摘Objective:To evaluate whether there would be a difference in outcome when the smaller ultra-mini 12 Fr sheath was used instead of the mini 16 Fr sheath for percutaneous nephrolithotomy(PCNL)in paediatric patients for stones less than 25 mm.Methods:This was a prospective cohort study of patients who underwent PCNL in our hospital in a 2-year period from July 2016 to June 2018 by a single surgeon.PCNL was performed in a prone position and tract was dilated to the respective size using single step dilatation.Laser was used to fragment the stone.Stone-free outcome was defined as absence of stone fragment at 3 months on kidney,ureter,and bladder X-ray.Results:There were 40 patients in each group.Mean stone size was comparable between the two groups(14.5 mm vs.15.0 mm).The procedure was completed faster in the 16 Fr group compared to 12 Fr group(24.5 min vs.34.6 min).Stone clearance was highly successful in both groups(97.5%vs.95.0%).There was no difference in complications between the two groups.The decrease in hemoglobin was minimal in both groups(0.2 g/dL vs.0.3 g/dL).Conclusion:We found that the success rates were similar in both mini PCNL and the smaller ultra-mini PCNL groups.No significant difference in bleeding was noted in our pilot study,however,operative time was longer in the ultra-mini group as compared to the mini sheath group.
文摘BACKGROUND Simultaneous acute ischemic stroke(AIS)and myocardial infarction(cardio-cerebral ischemic attack)have rarely been reported in the literature.Currently,no clear evidence-based guidelines or clinical trials exist to determine the optimal therapeutic strategy for these patients.CASE SUMMARY We present the case of a 27-year-old Chinese man who simultaneously experie-nced acute concomitant cerebrocardiac infarction(CCI)and painless ST-elevation myocardial infarction.The patient was successfully treated with elective percu-taneous coronary intervention(PCI)after receiving urgent systemic thrombolysis at the standard dose for AIS.CONCLUSION Urgent thrombolysis followed by elective PCI was an appropriate strategy for the management of simultaneous CCI.
文摘Bcakground: Pancreatic pseudocyst (PPC) is a common complication arising from acute or chronic pancreatitis, trauma, or pancreatic duct obstruction. When acute fluid collection persists for 4 - 6 weeks and is encapsulated by a fibrous wall, it is classified as a pancreatic pseudocyst. While PPC is generally asymptomatic in many patients, it can manifest with persistent abdominal pain, dyspepsia, intra-cystic infection, and potentially lead to gastrointestinal obstruction in some cases. Although smaller PPCs may resolve spontaneously, larger PPCs tend to be refractory to absorption and often necessitate surgical intervention to prevent complications such as intracystic hemorrhage. Objective: To explore the efficacy of percutaneous catheterization with negative pressure in the treatment of large pancreatic pseudocysts. Methods: The cases of large pancreatic pseudocysts treated in our hospital from 2004 to 2022 were retrospectively collected, and the general condition, operation time, drainage time, feeding time, postoperative complications, hospital stay, cost and follow-up of the patients were analyzed. Results: A total of 132 patients with large pancreatic pseudocysts were collected. The average operation time was 32.4 ± 2.1 min;The retention time of the drainage tube was 30 ± 1.8 days in the percutaneous negative pressure drainage group;The postoperative feeding time was no fasting after local anesthesia drainage;Postoperative complications (bleeding, infection, pancreatic leakage, recurrence, anastomotic leakage, etc.): Two of the 132 patients had recurrent cysts, which were cured by re-puncture and negative pressure drainage. The length of hospital stay was 6 ± 1.1 days;The cost was 11,200 ± 1300 yuan;Follow-up: The follow-up time ranged from 1 to 3 years, and the patients had no discomfort. Conclusion: Percutaneous catheterization and negative pressure drainage can effectively treat large pancreatic pseudocysts. Compared with other treatment methods, it is simple and effective, the postoperative recovery of patients is faster, the physical damage is less, the hospital stay is shorter, and the cost is lower.
文摘While cystolitholapaxy for bladder stones is commonly performed using a transurethral approach,large or complex stone burdens in patients with complex lower urinary tract anatomy may make this inefficient or infeasible.Percutaneous cystolitholapaxy is a safe,effective,minimally invasive alternative for diverse indications,including patients with benign prostatic hyperplasia,urethral stricture disease,closed bladder neck,continent catheterized channel,or other urinary diversion.In this article,we review the indications for and advantages of percutaneous cystolitholapaxy and describe our step-by-step technique for this procedure,including representative imaging and favored equipment.We also discuss preoperative and postoperative considerations,management of potential complications,strategies to optimize clinical outcomes and patient safety,and comparisons with transurethral approaches.Finally,we report outcomes from our institutional series of percutaneous cystolitholapaxy cases to highlight the safety and efficacy of the procedure.
文摘BACKGROUND Flat bone metastases are common in patients with advanced cancers,often resulting in severe pain,limited mobility,and reduced quality of life(QOL).Traditional treatment options,such as radiotherapy or systemic therapies,often fail to provide sufficient pain relief or improve functional outcomes in these patients.Microwave ablation(MWA)offers advantages,such as shorter pro-cedure times and larger ablation zones,while percutaneous osteoplasty(PO)enhances bone stability and prevents pathological fractures.Despite these be-nefits,the combination of these techniques for treating flat bone metastases re-mains underexplored.AIM To evaluate the efficacy and safety of C-arm computed tomography(CT)-guided MWA combined with PO for managing painful flat bone metastases,focusing on pain relief,functional improvement,and QOL enhancement.METHODS A total of 45 patients with refractory moderate-to-severe pain resulting from flat bone metastases who underwent C-arm CT-guided MWA combined with PO between January 2015 and January 2021 were included.The efficacy of the pro-cedure was assessed by changes in the visual analog scale(VAS),Oswestry disability index(ODI),and QOL,as well as the occurrence of complications.Tumor response was evaluated using RECIST v1.1 and mRECIST criteria,with overall response rate(ORR)and disease control rate(DCR)as the primary end-points.RESULTS No serious complications were observed in any of the patients.A significant reduction in VAS and ODI was noted at 1 week,1 month,and 3 months post-procedure.A marked improvement in QOL was observed at all follow-up points.Bone cement extravasation was observed in 10 patients;however,none exhibited significant clinical symptoms.Based on RECIST v1.1,the ORR was 26.7%and the DCR was 88.9%.The mRECIST evaluation revealed a higher ORR of 51.1%and DCR of 88.9%.CONCLUSION C-arm CT-guided MWA with PO provides a dependable and effective strategy for managing flat bone metastases.It demonstrates significant pain relief,improved functional outcomes,and enhanced QOL.This treatment combination also shows promising tumor response rates with a low complication profile.

文摘BACKGROUND Choledochal cyst is a rare biliary tract disorder with five subtypes categorized based on the anatomical location of cystic dilatation.Type IV(which affects the intrahepatic and extrahepatic ducts)is the most common subtype in adults.Its clinical manifestations are diverse and the disease can potentially become malignant.Currently,the mainstay treatment is surgical excision which is used as a definitive treatment to prevent complications and avoid carcinogenesis.However,the surgical operation for giant choledochal cysts is technically challenging.CASE SUMMARY Here,we present a case of a giant choledochal cyst in an 18-year-old female.The diagnosis of patient was confirmed through magnetic resonance cholangiopancreatography.The patient developed acute cholangitis,and was treated with percutaneous transhepatic cholangial drainage to alleviate symptoms.The final treatment approach was cyst excision followed by Roux-en-Y hepaticojejunostomy,which successfully achieved excellent postoperative recovery.CONCLUSION Ultrasonography and magnetic resonance cholangiopancreatography can effectively diagnose choledochal cysts.Combined percutaneous transhepatic cholangial drainage surgery for giant choledochal cysts is safe and effective.
文摘Ultrasound-guided percutaneous thermal ablation has gained popularity as treatment for malignant hepatic tumors.It was first introduced as ablation therapy for hepatocellular carcinoma and cirrhosis comorbidity.Recently,this technique has also been used in the treatment of intrahepatic cholangiocarcinoma for patients who are not eligible for surgical resection.There are several types of thermal ablation techniques.Radiofrequency ablation and microwave ablation are two common methods that induce necrosis of the lesions.Irreversible electroporation is a relatively new non-thermal technique and is suitable in cases where thermal ablation would be ineffective or dangerous(e.g.,malignant tumors close to vascular or biliary structures).Irreversible electroporation can induce tumoral necrosis without damage to vascular and biliary structures.The aim of this minireview was to describe the safety,efficacy,and clinical indications of these techniques in the treatment of patients with intrahepatic cholangiocarcinoma who are ineligible for surgery.
文摘BACKGROUND Percutaneous nephrolithotomy(PNL)is the standard treatment for medium-sized and large kidney stones.Many potential complications of PNL may warrant hospital readmission(HR)after discharge,threatening patient safety and increasing the costs.AIM To estimate the rate of unplanned HR after PNL and identify its urological and nursing-related predictors.METHODS One hundred sixty-one patients were prospectively studied for HR after PNL from April 2022 to December 2022.The relevant urological and nursing-related characteristics of patients with and without unplanned HR after PNL were studied for association with HR,using univariate and multivariate analyses.Variables such as the demographic characteristics,comorbidities,laboratory and imaging characteristics,dietary status,operative time,number of kidney punctures,blood loss,urinary tract infections,and the receipt of instructions for catheter care and activities of daily living were included.A risk score was created.RESULTS The mean age of patients with HR(44.4±12.7 years)and without HR(43.9±12.6 years)was similar(P=0.847).The overall stone-free rate was 88.8%.The total complication rate was 32.3%(52 patients),and the highest grade was IIIa,according to the modified Clavein grading system,resulting in an HR rate of 22.4%.History of preoperative pyuria(P=0.001),hydronephrosis(P=0.001)and mean stone size(P=0.012),multiple renal punctures(P<0.001),double J stent(P=0.033),total operative time(P=0.001),intraoperative injury(P=0.011),postoperative urinary tract infection(P<0.001),and inadequate instructions for urethral catheter(P=0.001)and activity daily living(P=0.048)were significantly associated with HR after PNL.On multivariate analysis,only preoperative pyuria(P=0.004),intraoperative injury(P=0.001),and inadequate instructions on urethral catheter care(P=0.035)were associated with HR.The risk score of the independent predictors was 0-17;0-4(low risk),5-9(moderate risk),and 10-17(high risk).CONCLUSION The rate of unplanned HR after PNL was relatively high(22.4%).The presence of pus cells in the preoperative urine analysis,intraoperative injury,and receiving inadequate instructions on urethral catheter care were independent predictors of HR after PNL.Combined studying of the urological and nursing-related predictors may promote the implementation of enhanced recovery protocols after PNL.
文摘BACKGROUND Severe acute cholangitis is a potentially life-threatening disease in low-middle income countries(LMIC).Due to limited endoscopic services,these patients mostly undergo percutaneous transhepatic biliary drainage(PTBD).Studies from developed countries reported more complications with PTBD as compared with endoscopic retrograde cholangiopancreatography(ERCP).AIM To compare safety,therapeutic success,and survival among the PTBD and ERCP procedure in severe cholangitis in LMIC.METHODS A retrospective study was conducted in the Aga Khan University Hospital from January 2017 to December 2023.All patients who had severe acute cholangitis and underwent ERCP or PTBD were included.Patients were followed for complications,procedure success,and mortality.Data was gathered through an electronic medical record system and analyzed usingχ²and two sample t-tests.RESULTS A total of 33 patients were recruited,consisting of 12 females and 21 males with a mean age of 61 years.Among these participants,12 patients underwent ERCP,and the remaining 21 patients underwent PTBD.Therapeutic success was seen more in the ERCP group[11/12(97.1%)]than in the PTBD group[12/21 patients(57.1%)].Post-procedure complications were seen in both groups;however,more were observed in the PTBD cohort with a significant P value of 0.02.There were no mortalities among the patients who underwent ERCP while 5(23.8%)mortalities were seen in the PTBD group.CONCLUSION Fewer post-procedure complications and deaths were observed after ERCP than after PTBD,laying the foundation for large prospective studies and shifting the local paradigm of acute cholangitis treatment in LMICs.
文摘BACKGROUND Gas-containing pseudocysts rarely cause of lumbar radiculopathy.This report describes successful treatment of a gas-containing pseudocyst using percutaneous transforaminal endoscopy.CASE SUMMARY A 48-year-old man presented with severe pain and numbness in his right leg,which worsened upon walking or weight bearing.Computed tomography and magnetic resonance imaging revealed a gas-containing cyst compressing the left L5 nerve root at the L4-5 level.The pseudocyst was successfully removed using a percutaneous transforaminal endoscopic discectomy.Vivid and clear endoscopic imaging of the pseudocysts was performed intraoperatively.The patient experienced immediate pain relief and was discharged one day after the operation.The patient returned to work.Moreover,numbness in the right leg returned to normal within 6 months.At the one-year follow-up,there was no symptoms recurrence.CONCLUSION Transforaminal endoscopy offers excellent surgical visualization and facilitates meticulous operative manipulation,making it a minimally invasive approach for treating gas-containing pseudocysts in the intervertebral foramen.
文摘BACKGROUND Percutaneous liver biopsies,including coaxial needle biopsy(CNB),are the pre-ferred method for tissue sampling to diagnose or characterize an array of hepatic conditions.Despite the advent of intraprocedural image guidance,and various“plugging”techniques,bleeding remains a frequent and potentially highly mor-bid complication,particularly in patients with bleeding risks.Thus,post-biopsy bleeding risk leads to extended patient monitoring,and in significant cases,ad-ditional imaging,intervention,and even surgery.Very rarely,death has resulted.CASE SUMMARY We report a series of five image-guided liver biopsy cases undertaken due to a variety of clinical conditions followed by the use of a new electrocautery hemo-stasis device called SinglePass Kronos.Indications for the CNB included non-alcoholic steatohepatitis,hepatocellular carcinoma and cirrhosis,abnormal liver function tests with positive autoimmune serologies,abnormal imaging findings,and jaundice.All biopsy procedures were successful with no complications th-rough 30 days following CNB.Post-procedure ultrasound confirmed the absence of bleeding in all five cases.CONCLUSION Hemostasis of CNB tracts using SinglePass Kronos was obtained in all cases.Ad-ditional study of this device is warranted.
文摘BACKGROUND It is well known that in case of high initial strictures of bile ducts surgical treatment is associated with a high risk of damage to the hepatoduodenal ligament elements,often involved in rough scarring,and with a significant risk of stricture recurrence.AIM To compare the long-term outcomes of different surgical treatment options for patients with high-grade benign biliary strictures.METHODS From 2012 to 2022,193 patients were treated at the A.V.Vishnevsky Surgical Center.All of them had different levels of strictures according to Bismuth-Strasberg classification:Type E1-2 in 32 patients,type E3-99,type E4-62.123 patients underwent open reconstructive interventions,70 percutaneous endobiliary interventions.RESULTS Long-term results were available for 192(99%)patients with a follow-up of 4.7±1.6 years after reconstructive surgery;3.0±1.4 years after percutaneous interventions.Excellent and good results(according to Terblanche classification)were achieved in 35%(42/122)of patients after open reconstructive surgery and in 13%(9/70)of patients after percutaneous transhepatic interventions(P-value<0.05).CONCLUSION Technically,the most difficult bile duct strictures for reconstructive and percutaneous transhepatic interventions with a high recurrence rate are Bismuth-Strasberg type E4 and E5.The comparative analysis of long-term results of percutaneous and open procedures showed a statistically significant advantage of percutaneous procedures compared to open reconstructive procedures.

文摘BACKGROUND Liver abscess is a serious hepatic infectious disease for which percutaneous drainage has become the preferred treatment method due to its minimally invasive advantages.With the rising prevalence of non-alcoholic fatty liver disease reaching 29.2%in Chinese adults,the number of patients with liver abscess combined with fatty liver has shown a significant increasing trend clinically.AIM To analyze risk factors affecting prognosis after percutaneous drainage in liver abscess patients with fatty liver.METHODS A retrospective analysis of 165 liver abscess patients with fatty liver who underwent percutaneous drainage from January 2020 to April 2024.Patients were divided into good prognosis(n=121,73.3%)and poor prognosis groups(n=44,26.7%)based on 30-day outcomes.Univariate and multivariate logistic regression analyses were performed to identify independent risk factors.RESULTS The poor prognosis group had older age(65.2±11.8 years vs 56.1±11.9 years,P<0.001),higher diabetes prevalence(70.5%vs 47.2%,P=0.008),elevated inflammatory markers,and lower serum albumin(26.8±4.2 g/L vs 32.1±5.6 g/L,P<0.001).Moderate-to-severe fatty liver was more prevalent in the poor prognosis group(68.2%vs 38.0%,P=0.001).Multivariate analysis identified five independent risk factors:Age≥65 years(OR=2.847,P=0.007),diabetes history(OR=3.124,P=0.003),abscess diameter≥8 cm(OR=2.591,P=0.015),serum albumin<30 g/L(OR=3.456,P=0.001),and moderate-to-severe fatty liver(OR=2.213,P=CONCLUSION)Advanced age,diabetes history,large abscess,hypoalbuminemia,and moderate-to-severe fatty liver are independent risk factors for poor prognosis after percutaneous drainage in liver abscess patients with fatty liver.
文摘BACKGROUND Optical coherence tomography(OCT)offers detailed cross-sectional imaging during percutaneous coronary intervention(PCI),aiding in anatomically complex coronary lesions.Despite its advantages,evidence on the clinical effectiveness of OCT-guided PCI remains limited.Major databases were systematically searched for randomized controlled trials(RCTs)comparing OCT-guided and angiography-guided PCI in complex lesions.Primary outcomes included major adverse cardiovascular events(MACE)and target vessel failure(TVF);secondary outcomes included mortality,myocardial infarction(MI),and other procedural outcomes.A random-effects model was used to pool risk ratio(RR),with 95%CI.Statistical analysis was conducted in R software(v4.4.1),with significance set at P<0.05.RESULTS Five RCTs(5737 patients)showed OCT-guided PCI significantly reduced MACE(RR:0.63,95%CI:0.52-0.77,P<0.01),TVF(RR:0.68,95%CI:0.56-0.83,P<0.01),all-cause(RR:0.58,95%CI:0.38-0.87,P<0.01)and cardiac mortality(RR:0.43,95%CI:0.24-0.76,P<0.01),target-lesion revascularization(RR:0.53,95%CI:0.33-0.84,P<0.01),stent thrombosis(RR:0.52,95%CI:0.31-0.86,P=0.01),and target-vessel MI(RR:0.64,95%CI:0.42-0.97,P=0.04)vs angiography-guided PCI.Periprocedural MI,any revascularization,target-vessel revascularization,and contrast-associated kidney injury were similar between groups.CONCLUSION OCT-guided PCI improves outcomes in complex lesions by reducing MACE,TVF,mortality,stent thrombosis,and target-vessel MI.These findings highlight the need for further large-scale RCTs to confirm its benefits.
文摘Anxiety disorders following percutaneous coronary intervention for acute myocardial infarction affect approximately 20%-40%of patients,with a significantly greater prevalence in females(OR=1.8).These disorders manifest through physiological symptoms,cognitive distortions,behavioral avoidance,and cardiacspecific concerns and typically emerge within 1-2 weeks post-procedure.Key risk factors include female sex,younger age(<55 years),psychiatric history,procedural complexity,and poor social support.Anxiety negatively affects cardiovascular outcomes when left untreated,leading to higher readmission rates(HR=1.47)and recurrent cardiovascular events(HR=1.31),as well as lower medication adherence and quality of life.Screening is optimally conducted 7-10 days postprocedure via validated tools such as the Hospital Anxiety and Depr-ession Scale,Anxiety.Heart-specific cognitive behavioral therapy(SMD=-0.72),selective serotonin reuptake inhibitors(especially sertraline),and integrated cardiac rehabilitation programs that incorporate both psychological and physical elements are among the beneficial interventions that have been supported by evidence.These all-encompassing strategies show long-term improvements in cardiovascular outcomes,functional ability,and healthcare expenses in addition to immediate benefits in lowering anxiety.Digital initiatives have the potential to increase access,especially in underprivileged areas.Early identification of highrisk patients and implementation of timely,targeted interventions represent crucial strategies for improving both psychological and cardiovascular outcomes in this vulnerable population.
