A 35-year-old black woman presented with thrombosis of an anomalous right subclavian artery and distal arterial embollzation. Initially, her right subclavian artery was reimplanted onto the common carotid artery, and a brachial artery embolectomy plus intraoperative thrombolytic therapy were used to reopen her distal arterial circulation. When her brachial artery repair thrombosed the following day, a distal ulnar artery bypass and repeat thrombolytic therapy were required to restore arterial patency. Six months later, she returned with severe, progressive, neointimal hyperplasla of her brachial artery and a second attempt at arterial reconstruction was unsuccessful. She eventually required a right below-elbow amputation. This patient demonstrated an anomalous right subclavian artery that presented with distal embolization without an antecedent history of severe atherosclerotic disease or the development of a right subclavian artery aneurysm. A review of the medical literature relating to complications of this anomaly is provided.
