Intrathoracic atherosclerotic aneurysm of the right subclavian artery. A case report.

The intrathoracic subclavian artery is a rare location for a peripheral arterial atherosclerotic aneurysm when compared with the femoral and popliteal arteries. Resection of the aneurysm and replacement with a prosthetic graft has come to be the most commonly performed procedure for this problem. Because of the tight adherence of surrounding tissues such as the vagal nerve, phrenic nerve, jugular veins, and their branches, we preferred an exclusion method with revascularization to the aneurysmorrhaphy and achieved a good result. We report the clinical aspects of such a case.
