Abstract
We report the multi-detector-row ct-angiography (MDCTA) findings of two patients with an uncommon origin of the left common carotid artery from the innominate artery. Post-processed images clearly show the anomaly of origin. In one case we observe also an important stenosis located at the left internal carotid artery origin. In the second part of this paper we review the literature about this type of vascular variant. A through knowledge of these anatomic variants and the potential vascular pathologies that may potentially coexist, is necessary before treating the aortic arch vessels.
