Endovascular Aortic Repair for Isolated Infrarenal Aortic Stenosis.

An 87-year-old man with severe intermittent claudication and lower limb pain at rest was referred to our hospital for examination. Computed tomography (CT) angiography imaging showed a severe stenosis in the infrarenal abdominal aorta. The ankle brachial indices (ABIs) were 0.62 (right) and 0.60 (left). Endovascular aortic repair was performed with distal protection. The postoperative course was uneventful, and postoperative CT showed no stenosis or distal embolization. The ABI improved to the normal values of 1.02 (right) and 1.13 (left). The patient was followed up as an outpatient without a cane. Long-term follow-up and randomized controlled trials are necessary to clarify the durability and efficacy of the endovascular approach for this aortic pathology.
