Carotid stenting in the bovine arch

Abstract

We report our experience in stent-supported angioplasty of the left internal carotid artery in patients with anomalous origin of the left common carotid, the so-called bovine arch, in which the right brachiocephalic and left carotid share a common trunk from the aortic arch. The occurrence of the anatomic variant is discussed, and techniques of femoral, brachial, and radial approaches are described.
