Carotid stenting through the right brachial approach for left internal carotid artery stenosis and bovine aortic arch configuration.

Unfavorable complex anatomy or congenital anomalies of supra-aortic vessel take-off may increase carotid artery stenting (CAS) procedural difficulties and complications through the femoral route. We assessed the feasibility, safety, and efficacy of CAS through the right brachial approach in patients in whom left internal carotid artery stenosis and bovine aortic arch configuration were identified with computed tomography (CT) angiography. Bovine configuration of the aortic arch and left carotid artery stenosis were easily identified by CT angiography and successfully treated through the right brachial approach technique.
