Delayed Superficial Femoral Artery Stent Erosion and Pseudoaneurysm Following Endovascular Therapy for Occlusive DiseaseVascular Surgery Section, Southern Arizona Veterans Affairs Health Care System (SAVAHCS), and University of Arizona Health Science Center (AHSC), Tucson, Arizona, luis.leon{at}va.gov
Vascular Surgery Section, Southern Arizona Veterans Affairs Health Care System (SAVAHCS), and University of Arizona Health Science Center (AHSC), Tucson, Arizona 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.
Key Words: superficial femoral artery pseudoaneurysm endovascular stent graft atherosclerosis
