The primary endpoints focused on procedure-related outcomes such as patency and limb salvage, whereas overall survival was assessed as a key secondary outcome. The patients were divided into the CLTI (n=20) and IC (n=43) groups; the anesthesia type, additional revascularization, blood loss, hospital stay, complications, and survival were compared. Multivariable Cox regression analysis was performed to identify independent predictors of mortality.</p><p><strong>Results: </strong>Patients with CLTI had higher rates of local anesthesia, additional revascularization (all performed concomitantly), greater blood loss, and longer hospital stays. Despite the 100% technical success in both groups, 30-day mortality and complications occurred only in the CLTI group. Kaplan-Meier analysis showed similar patency and limb salvage rates between groups, whereas survival rates were significantly lower in patients with CLTI (P=0.037). Multivariable analysis revealed that CLTI itself was not an independent predictor of mortality; rather, a worse systemic status (e.g., higher American Society of Anesthesiologists classification) showed a trend toward poorer outcomes (P=0.051). No significant differences were found between the patch types.</p><p><strong>Conclusion: </strong>TEA provides effective mid-term outcomes in patients with CFA disease, particularly those with IC. Although patients with CLTI show poorer survival, this appears to be driven more by systemic comorbidities than by the limb status itself. Careful preoperative assessment and holistic management of general health are essential to optimize outcomes, particularly in high-risk populations.</p>","PeriodicalId":52311,"journal":{"name":"Vascular Specialist International","volume":"41 ","pages":"18"},"PeriodicalIF":1.0,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12311306/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144755103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
