Surgical treatment for aneurysm at the origin of an aberrant right subclavian artery.
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.
