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.
巨细胞动脉炎（GCA）是一种常见的导致颅血管炎的病因，常表现为头痛和颌跛行。在此，我们报告一例患有GCA的女性病例，该患者表现为严重的下肢缺血。尽管接受了最佳的药物治疗，但她仍出现了进行性小腿跛行和右脚溃疡。检查结果高度提示GCA累及股浅动脉。通过血管成形术和植入药物洗脱支架，该肢体成功实现了血管再通。GCA是下肢缺血的一个重要病因，对于没有动脉粥样硬化证据的患者应予以考虑。血管内介入治疗是治疗GCA所致严重肢体缺血的一种可行方法，且在本病例中已证明是安全的。
