A rare case of bilateral subclavian artery agenesis

Abstract

Arterial agenesis is a rare condition and has been reported to affect the internal carotid artery, common carotid artery, and pulmonary artery. However, to the best of our knowledge, it has not yet been reported to affect the subclavian arteries. We present a case of asymptomatic bilateral subclavian artery agenesis and left subclavian artery aneurysm. This patient's abnormal vasculature was found incidentally. Despite being asymptomatic, repair of the aneurysm via vertebral transposition and ligation of the subclavian artery was performed to prevent eventual thrombosis, emboli, and stroke.
