title: Delayed superficial femoral artery stent erosion and pseudoaneurysm following endovascular therapy for occlusive disease.
abstract: A 78 year-old male with multiple serious medical comorbidities was diagnosed with a pseudoaneurysm of the proximal superficial femoral artery. He had undergone successful superficial femoral artery (SFA) stenting for limb salvage four months previously and a Duplex ultrasound had confirmed adequacy of the endovascular procedure two months after its execution. This was successfully treated with placement of a covered-stent at the proximal SFA and a balloon-expandable stent at the origin of the deep femoral artery. Unfortunately the patient expired six weeks after the last endovascular intervention, likely due to procedural-unrelated causes. We postulate delayed stent erosion of a proximal atherosclerotic SFA, causing the pseudoaneurysm. This is the first report of such a case in the literature.
