Surgical treatment of an infected popliteal artery aneurysm 12 years after aneurysm exclusion and bypass.

The presence of persistent blood flow in popliteal artery aneurysms that have been treated with exclusion and bypass is surprisingly common. Complications from incompletely excluded aneurysms include aneurysm enlargement, local compressive symptoms, and sac rupture. Infection of a previously excluded and bypassed popliteal artery aneurysm is a notably rare complication. In this case report, we describe a patient with an infection of a popliteal artery aneurysm 12 years following surgical repair. The patient was successfully treated with aneurysm resection and soft tissue debridement.
