Isolated abdominal aortic dissection is a rare type of aortic dissection. This disease may be accompanied by complications like abdominal pain, and intestinal and lower limb ischemia. We report a case of isolated abdominal aortic dissection with intermittent claudication which was successfully treated by an endovascular stent graft procedure. A man in his 90s was referred to our hospital with the complaint of intermittent claudication. His bilateral ankle-brachial pressure index (ABI) was approximately 0.65. Computed tomography (CT) scan revealed an isolated abdominal aortic dissection with true lumen compression which caused lower limb ischemia. Endovascular aortic repair was planned and a stent graft, VELATM Proximal Endograft (Endologix, Irvine, USA), was placed in the dissected abdominal aorta. The ABI was bilaterally restored to over 1.00, and the symptom of intermittent claudication has been absent since the endovascular aortic repair.
