Superficial temporal artery access for transfemoral or transbrachial carotid artery stenting in selected patients considered unfit for carotid surgery

Transfemoral (TFCAS) or transbrachial carotid artery stenting (TBCAS) is an alternative to carotid endarterectomy (CEA) for treatment of high-grade internal carotid artery (ICA) stenosis. A difficult aortic arch (i.e., type III or bovine arch) and/or a tortuous/stenosed common carotid artery (CCA) are potential reasons for technical failure. This study explores the benefits of superficial temporal artery access (STAA) in aiding TFCAS or TBCAS for patients with challenging anatomical conditions.
