RESUMO

Introdução: Os autores elaboraram um estudo retrospectivo de todos os casos clínicos admitidos no seu Serviço com o diagnóstico de aneurisma poplíteo ao longo de 5 anos.

Material e Métodos: Para atingir esse objectivo, procederam à consulta dos processos hospitalares de todos os doentes admitidos com o diagnóstico de aneurisma poplíteo entre 01 de Janeiro de 2004 e 31 de Dezembro de 2008.

Resultados: De um total de 61 doentes, 37 (60,7%) apresentavam aneurismas bilaterais. Desses 61 doentes, 58 eram do sexo masculino e 3 do feminino, sendo a média de idades de 66,9 ± 11,6 anos. 36,1% dos doentes apresentavam também aneurismas noutras localizações. Os aneurismas eram, na sua maioria, assintomáticos. Quando sintomáticos, a forma de apresentação mais frequente foi a isquémia aguda por trombose do aneurisma. Dentro da totalidade dos aneurismas poplíteos (n=98), 37 foram operados electivamente, 29 de urgência e 32 não foram operados. As intervenções cirúrgicas de eleição foram a exclusão do aneurisma através de bypass femoro-poplíteo distal com veia safena interna (n=48) ou com prótese (n=16). As taxas de patência primária aos 30 dias foram de 98% com o uso de veia e de 68,8% com prótese, tendo motivado 3 amputações supracondilianas.

Conclusões: Os aneurismas poplíteos são mais prevalentes no sexo masculino, frequentemente bilaterais, e existe uma forte relação entre estes e aneurismas noutras localizações/megadistrofia arterial generalizada. O tratamento cirúrgico ideal é o realizado electivamente com material autólogo, sendo as taxas de patência com o recurso a material protésico bastante inferiores.

Popliteal Aneurysms – retrospective study

ABSTRACT

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.
