Management of of arteriosclerotic aneurysm of the innominate artery.

Arteriosclerotic aneurysm of the innominate artery is an unusual lesion. A review of the literature has revealed many approaches to this problem in the past, but the mortality rate has remained significant and serious complications have been frequent. Computerized axial tomography and noninvasive cerebrovascular methods can be useful in managing this lesion. Vein grafts from the ascending aorta to the common carotid and subclavian arteries were used to revascularize a patient following resection of an innominate aneurysm.
