BAPTISTA, Ana et al. Popliteal Aneurysms: retrospective study. Angiol Cir Vasc [online]. 2010, vol.6, n.4, pp.188-194. ISSN 1646-706X.

Introduction: The authors performed a 5-year retrospective study of all the case reports admitted in their Department with the diagnosis of popliteal aneurysm. Material and Methods: To achieve that purpose, the clinical files of all the patients admitted with the diagnosis of popliteal aneurysm between January 1st 2004 and December 31st 2008 were reviewed. Results: From a total of 61 patients, 37 (60,7%) had bilateral aneurysms. Of those 61 patients, 58 were males and 3 were females. The mean age was 66,9 ± 11,6 years. 36,1% of the patients had also aneurysms in other locations. The majority of the aneurysms were asymptomatic. When symptomatic, the most frequent presentation was acute ischemia caused by thrombosis of the aneurysm. Of all the popliteal aneurysms (n=98), 37 were repaired electively, 29 urgently and 32 were not repaired. The most used surgical interventions were the exclusion of the aneurysm by distal femoropopliteal bypass with greater saphenous vein (n=48) or with prosthesis (n=16). Primary patency rates at 30 days were of 98% with vein and of 68,8% with prosthesis, which caused 3 transfemoral amputations. Conclusions: Popliteal aneurysms are more prevalent in males, frequently bilateral and there is a strong connection between them and aneurysms in other locations/arteriomegaly. The ideal surgical treatment is the elective repair with autologous material, being the patency rates with prosthesis inferior to the ones with vein.
