Abstract

A 57 year-old patient developed transient blindness and impending syncope whenever he tumed his head to the right side. The angiography showed severe focal luminal narrowing of the right vertebral artery at the level of C5-C6 interspace with head tumed to the right, but showed normal filling of the right vertebral artery in the straight position. The distal cervical portion of the left vertebral artery was hypoplastic We believe that symptoms of this patient are due to the right vertebral artery compression produced by osteophyte formed at uncinate portion of the vertebrae on head tuming to the right. This patient also experienced transient global amnesia for about four hours after the right vertebral arteriography performed with head tumed to the right.
