Resumo

Paciente relatava história aguda de dor e edema em membro inferior direito há 5 dias, e a semiologia caracterizava pulsos poplíteos amplos e perfusão distal satisfatória. Exames laboratoriais mostraram insuficiência renal, e o exame de ultra-som duplex evidenciou um aneurisma de artéria poplítea à direita roto, com formação de pseudo-aneurisma e um aneurisma de artéria poplítea à esquerda. O paciente foi submetido à exploração cirúrgica por via de acesso posterior, sendo evidenciado pseudo-aneurisma secundário a aneurisma de artéria poplítea roto e realizada endoaneurismorrafia com interposição de veia. A evolução pós-operatória foi boa. A ruptura de um aneurisma de artéria poplítea é uma complicação rara, e apenas um relato de formação espontânea de pseudo-aneurisma foi encontrado na literatura.

Abstract

The patient presented with a 5-day history of acute pain and swelling in the right lower limb. On physical examination, wide popliteal pulses and satisfactory distal perfusion were observed. The laboratory work-up showed renal failure and the duplex ultrasound examination was suggestive of a ruptured right popliteal artery aneurysm with pseudoaneurysm formation and a left popliteal artery aneurysm. The patient underwent urgent surgery through a posterior popliteal approach. A ruptured aneurysm with pseudoaneurysm formation was found and repaired by endoaneurysmorrhaphy with interposition of a short saphenous vein segment. The postoperative period was unremarkable. Rupture of a popliteal artery aneurysm is a rare complication: a single report of spontaneous popliteal pseudoaneurysm was found in the literature.
