Endovascular treatment of critical lower limb ischemia caused by giant cell arteritis

Abstract

Giant cell arteritis (GCA) is a well-known cause of cranial vasculitis often presenting with headache and jaw claudication. Here we report the case of a woman suffering GCA who presented with critical lower limb ischemia. Despite best medical therapy, she developed progressive calf claudication and ulceration of the right foot. The findings on workup were highly suggestive of GCA involving the superficial femoral artery. The limb was successfully revascularized with angioplasty and placement of a drug-eluting stent. GCA is an important cause of lower limb ischemia and should be considered in patients without evidence of atherosclerosis. Endovascular intervention is a feasible treatment of critical limb ischemia due to GCA and has been shown to be safe in this case.
