title: Surgical treatment for aneurysm at the origin of an aberrant right subclavian artery.
abstract: Atherosclerotic aneurysms at the origin of an aberrant right subclavian artery (ARSA) are extremely rare entities of congenital origin. We report a case of a 62-year-old man who presented with dyspnea and upper chest pain. The CT scan and digital subtraction angiography revealed a 7-cm aneurysm of an ARSA arising from Kommerell's diverticulum. Deep hypothermic circulatory arrest was instituted and a transaortic approach was used for closure of the origin of the aneurysm with a prosthetic patch. A Dacron graft was interposed between the right subclavian artery and the ascending aorta and the aneurysmal sac was resected. The patient had an uneventful recovery.
