Abstract:
During evaluation of a man for claudication, abnormal chest roentgenographic results were found. Computed tomography documented a 6.5-cm aneurysm of an aberrant retroesophageal right subclavian artery. Interruption of the right subclavian artery with an end-to-side subclavian-carotid anastomosis was performed via a right supraclavicular incision, followed immediately by left transthoracic interruption of the origin of the right subclavian artery using a heparin-bonded shunt. This approach avoids previously reported embolic complications while preserving brachial blood flow and providing safe access to the aorta.
