Osteonecrosis of Femoral Head Occurred after Stent Placement of Femoral Artery

Abstract

We present a case of osteonecrosis of femoral head (ONFH) that occurred after stent angiography of femoral artery for the treatment of arteriosclerosis obliterans (ASO) of left inferior limb in a 76-year-old woman. No case of late collapse of femoral head as a complication of endovascular procedure such as stent placement has been previously documented. We considered that ONFH occurred after detaining stent at a junction of left deep femoral artery for the treatment of the ischemia of left lateral and medial femoral circumflex artery.
