Endoleaks, characterised by persistent flow within the aneurysm sac after repair, can cause sac expansion, increasing the risk of adverse outcomes, including the formation of cutaneous fistulae, a rare but potentially severe complication.</p></div><div><h3>Report</h3><p>A 75 year old male with a history of previous bilateral PAA exclusion with a left femoropopliteal bypass using reversed great saphenous vein (GSV) graft in 2012 and a right femoropopliteal bypass using a PTFE prosthesis in 2017, both through medial approach, presented with pain and ulceration in the left popliteal region. Previous angiography had shown residual arterial flow through collateral vessels, requiring thrombin injection. Bilateral bypass thrombosis had also occurred after discontinuing anticoagulation. Computed tomography angiography confirmed a complicated excluded left popliteal aneurysm with superinfection. The patient underwent elective surgery, involving partial aneurysmectomy, endoaneurysmorrhaphy, and fistulectomy through a posterior approach. Post-operatively, the patient experienced resolution of symptoms and inflammatory signs.</p></div><div><h3>Discussion</h3><p>The optimal approach for treating PAAs remains a subject of debate, with some experts advocating the posterior approach to prevent sac growth. However, others support the medial approach, reporting satisfactory results. In this case, the medial approach resulted in incomplete exclusion, leading to sac expansion and a cutaneous fistula. Timely re-intervention through the posterior approach successfully resolved the complication. This report highlights a rare but serious complication of incomplete PAA exclusion. Vigilant post-operative surveillance and intervention are crucial to manage such cases effectively. Further research is warranted to determine the optimal approach for PAA repair and prevent associated complications.</p></div>","PeriodicalId":36502,"journal":{"name":"EJVES Vascular Forum","volume":"61 ","pages":"Pages 77-80"},"PeriodicalIF":0.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666688X24000522/pdfft?md5=060a06649afe7a00897c3ffb5eb60c72&pid=1-s2.0-S2666688X24000522-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139828424","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}
