Surgical management of a superficial femoral artery aneurysm in a patient with a high risk of thromboembolism.

A 62-year-old man with a history of proteinase 3-specific antineutrophil cytoplasmic antibody-associated vasculitis, antiphospholipid syndrome, and deep vein thrombosis presented with an asymptomatic 15-mm-diameter right superficial femoral artery (SFA) aneurysm, showing increased intraluminal thrombus on computed tomography compared to 2 years prior. Despite anticoagulation, thrombus progression prompted surgery to prevent embolization. The right SFA atherosclerotic aneurysm was resected. A reversed femoral vein graft was used for arterial reconstruction. Three-year follow-up computed tomography showed no aneurysm or pseudoaneurysm at the reconstructed site. Surgery was successful in this case of a right SFA aneurysm at a high thrombosis risk.
