Intermittent claudication caused by small aorta syndrome: a case report and review of literature.

Aortoiliac arterial steno-occlusions in young or middle-aged patients are relatively rare and have been reported in the literature as small aorta syndrome (SAS) or hypoplastic aortoiliac syndrome. We report the case of a 48-year-old Japanese woman with intermittent claudication caused by SAS. We performed left iliofemoral bypass grafting with a Dacron graft via a retroperitoneal approach. Bypass grafts, endarterectomy, and sympathectomy have been used for surgical management. Given that post-procedural event rates are higher for SAS than for other common atherosclerotic diseases, patients with SAS should be closely followed up after surgery.
