Abstract

Anastomotic false aneurysms are rare after autologous vein bypass. However, such lesions have the potential for life or limb-threatening complications, and their management can be extremely challenging. Here, we describe a 62-year-old male patient who developed a false aneurysm at the proximal anastomosis after a femoro-popliteal bypass. His left upper limb cephalic vein had been used as the conduit. The false aneurysm was successfully managed by percutaneous injection of fibrin sealant. This report aims to highlight this rare complication and its successful percutaneous management, with preservation of the bypass graft.

Resumo

Pseudoaneurismas anastomóticos são raros após bypass venoso autólogo. No entanto, tais lesões têm potencial para desenvolver complicações que ameaçam a vida ou os membros do paciente, e seu manejo pode ser extremamente desafiador. Neste estudo, descrevemos o caso de um paciente do sexo masculino, 62 anos, que desenvolveu pseudoaneurisma na anastomose proximal após bypass femoropoplíteo. A veia cefálica do membro superior esquerdo foi usada como conduto. O pseudoaneurisma foi tratado com sucesso por injeção percutânea de selante de fibrina. Este relato tem como objetivo destacar tal complicação rara e seu manejo percutâneo bem-sucedido, com preservação do enxerto de bypass.
