ABERRANT RIGHT SUBCLAVIAN ARTERY ANEURYSM - AN ANALYSIS OF SURGICAL OPTIONS

During evaluation of a man for claudication, abnormal chest roentgenog raphic results were found. Computed tomography documented a 6.5-cm ane urysm of an aberrant retroesophageal right subclavian artery. Interrup tion of the right subclavian artery with an end-to-side subclavian-car otid anastomosis was performed via a right supraclavicular incision, f ollowed immediately by left transthoracic interruption of the origin o f the right subclavian artery using a heparin-bonded shunt. This appro ach avoids previously reported embolic complications while preserving brachial blood now and providing safe access to the aorta.
