Right vertebral artery arising from the right common carotid artery with an absent brachiocephalic trunk
Abstract
The right and left vertebral arteries are the first branches of the ipsilateral subclavian arteries. However, in the presence of anatomical variation due to complex embryogenesis, the vertebral artery can arise directly from the aortic arch or any of its major branches. The atypical origin of the vertebral artery is commonly associated with the left vertebral artery. Anatomical variation in the origin of the right vertebral artery is rare. Most available reports are case reports from international studies. We report on a case of right vertebral artery arising from the ipsilateral common carotid artery with an absent brachiocephalic trunk in a South African patient examined by digital subtraction angiography. Reports on anatomical variations are of diagnostic importance prior to surgical interventions or endovascular treatment of cerebrovascular diseases such as cerebral aneurysms and arteriovenous malformations.
Keywords: Anatomical variation; Arch of the aorta; Brachiocephalic trunk; Common carotid artery; Vertebral artery.
