A rare case of persistent primitive first cervical intersegmental artery (proatlantal artery II) is reported. A 58-year-old @entity1 was admitted to our hospital with @entity4653 and @entity1269 . On admission he was stuporous with @entity912 and @entity1269 . CT scan on admission showed low density areas in the right cerebellar hemisphere and ventricular part of the pons. Right retrograde brachiography revealed @entity432 , aplasia of the right vertebral artery and an abnormal vessel connecting the right external carotid artery and the right vertebral artery. This anastomotic vessel was thought to be a persistent primitive first cervical intersegmental artery (Proatlantal artery II). Left carotid angiography revealed the left posterior cerebral artery was visualized through the posterior communicating artery, leading from the internal carotid artery. Left retrograde brachial angiography showed that the left vertebral artery terminated just distal from the branching of the left posterior @entity5487 .
