Abstract
The present report describes a patient with bilateral occipital arteries of internal carotid origin, which is an extremely rare variation, and left vertebral artery ostial stenosis diagnosed by selective catheterization and digital subtraction angiography.
Highlights
The present report describes a patient with bilateral occipital arteries of internal carotid origin, which is an extremely rare variation, and left vertebral artery ostial stenosis diagnosed by selective catheterization and digital subtraction angiography
Selective carotid and vertebral angiographies were performed in order to confirm the stenoses in proximal parts of both internal carotid arteries; occipital arteries were arising from the cervical segments of internal carotid arteries on both sides (Fig. 1)
Selective right vertebral angiography revealed the patency of the artery with hypoplasia of V3–V4 segments and intracranial and intervertebral collateral flow to the left vertebral artery (Fig. 2)
Summary
The present report describes a patient with bilateral occipital arteries of internal carotid origin, which is an extremely rare variation, and left vertebral artery ostial stenosis diagnosed by selective catheterization and digital subtraction angiography. Anomalous origin of the occipital artery from internal carotid artery is an extremely rare variation [2,3,4,5,6,7,8,9,10,11,12,13] Bilaterality of this variation is much more rare in the literature and there are only two cases reported previously [2,3,4,5,6,7,8,9,10,11,12,13]. A baloon-expandable intravascular stent was placed to the ostium of the left vertebral artery in order to treat the high grade stenosis (Fig. 3B)
