The right vertebral artery arises from the right common carotid artery. Other vascular variants are present including a retro-esophageal aberrant right subclavian artery and the left vertebral artery arising from the aortic arch between the left common cartoid and left subclavian arteries.
It is rare for the vertebral artery to arise from a common carotid artery. As is common, this patient has several other vascular anatomic variants.
The vertebral artery may arise from the CCA, ICA or ECA 1 but this is very uncommon.
