Aneurysmal degeneration of the superficial femoral artery following stenting: An uncommon infectious complication

Infrainguinal angioplasty and stenting is becoming a more commonly performed procedure. Its durability remains a matter of debate, however. Aneurysmal degeneration following angioplasty and stenting is a complication not previously described in the literature with regard to the superficial femoral artery. We present a case in which two aneurysms of the superficial femoral artery developed following angioplasty and multiple-stent placements in a patient who had previously undergone a failed femoral-to-below-the-knee popliteal artery PTFE bypass graft. The patient presented to our institution with an occluded, infected bypass graft. He was treated with graft and femoral artery/stent excision and vein bypass grafting. A brief review of infectious complications after stent placement is included.
