title: Symptomatic occipital-vertebral anastomosis - a case report.
abstract: Occipital-vertebral anastomosis (O-V anastomosis) is a common collateral anastomosis between the external carotid and the vertebro-basilar system. But symptomatic O-V anastomosis is rare. We report a case with syncope and vertebrobasilar insufficiency caused by O-V anastomosis. It was thought that the vertebral steal phenomenon through this anastomotic channel caused these symptoms.
