title: Persistent sciatic artery in a patient with extracranial internal carotid artery aneurysm and infrarenal abdominal aortic aneurysm. A case report.
abstract: A rare case of a persistent sciatic artery (PSA) in a patient with aneurysms of the internal carotid artery and abdominal aorta is presented. A 70-year-old man was referred with intermittent claudication of the right lower extremity. Angiography and computed tomography demonstrated that this symptom was due to occlusion of the PSA. On preoperative examinations, aneurysms of the extracranial internal carotid artery and abdominal aorta were incidentally discovered, and then surgically treated prior to the management of PSA. Systemic examinations must be performed in patients with PSA in order to scrutinize associated anomalies or vascular disease.
