An anomalous origin of the right vertebral artery (VA) from the right internal carotid artery (ICA) occurs only rarely. A 70-year-old man underwent carotid artery stenting for right internal carotid artery stenosis. In this patient, the right VA arose from the right ICA associated with an aberrant right subclavian artery. Embryologically, failure of involution of 1 of the first 6 intersegmental arteries causes various abnormal origins of the VA. The embryonic development of this anomaly is also reviewed.

D016893 Carotid Stenosis Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).
