Aneurysm of the innominate artery with aberrant origin of the left carotid artery. Case report.

Aneurysms of the supra-aortic vessels represent an unusual form of aneurysmal disease. Usually detected as asymptomatic masses, such aneurysms may cause life-threatening complications. We describe our surgical treatment for an aneurysm of the innominate artery that gave anomalous origin to the left carotid artery; the literature regarding such lesions is also reviewed.
