Native superficial femoral artery peripheral atherectomy site pseudoaneurysm: a case report.

Abstract

A 45-year-old woman who presented with blue toe syndrome was treated with atherectomy for a focal plaque located in the superficial femoral artery. She subsequently developed a large pseudoaneurysm at the atherectomy site requiring multiple sequential endovascular procedures in order to maintain in-line blood flow to the foot. Pseudoaneurysm formation at native peripheral artery atherectomy site has not been reported previously. We discuss possible complications of atherectomy and the possible mechanism of pseudoaneurysm formation after atherectomy. We address the importance of understanding risks of these minimally invasive procedures along with planning follow-up duplex and potential bail-out tactics.
