Idiopathic popliteal artery pseudoaneurysm: emergency diagnosis and treatment

Abstract

Pseudoaneurysms or false aneurysms of the popliteal artery are uncommon arterial disorders. These disorders most commonly result from trauma and iatrogenic lesions following orthopedic procedures. The authors report a rare case of popliteal artery pseudoaneurysm in which etiology was unknown. The authors also demonstrate that Doppler ultrasonography may be sufficient for planning vascular surgical procedures and that the open surgical approach is the treatment of choice for cases in which the symptomatic lesion causes local compression.Keywords: aneurysm, false; popliteal artery; ultrasonography, Doppler; vascular surgical procedures. ResumoPseudoaneurismas ou aneurismas falsos de artéria poplítea são doenças arteriais incomuns. Eles resultam, mais frequentemente, de traumatismos e lesões iatrogênicas após procedimentos ortopédicos. Os autores relatam um raro caso de pseudoaneurisma de artéria poplítea para o qual não foi encontrada etiologia. Demonstram ainda que a ultrassonografia com Doppler pode ser suficiente para o planejamento de procedimentos cirúrgicos vasculares, sendo a abordagem aberta a escolha para casos em que se tenha uma lesão com sintomas compressivos locais.Palavras-chave: aneurisma falso; artéria poplítea; ultrassonografia; Doppler; procedimentos cirúrgicos vasculares.

Successful Interventional Treatment of a Huge Pseudoaneurysm of the Popliteal Artery Caused by a Percutaneous Balloon Angioplasty Complication: A Case Report

“…Popliteal artery pseudoaneurysm is an uncommon clinical entity, accounting for less than 4% of all popliteal artery aneurysms. A popliteal pseudoaneurysm can result from changes in bone structure such as exostosis, osteochondroma, and fracture, or from iatrogenic causes including surgery and trauma ( 3 4 5 ). Pseudoaneurysm formation is a relatively slow process, requiring a long period to become symptomatically apparent after the initial trauma.…”
