Dissecting aneurysm of the vertebral artery.
A patient presented with a subarachnoid hemorrhage associated with a vitreous hemorrhage. Angiography was first interpreted as revealed a saccular aneurysm at the junction of the vertebral and posterior inferior cerebellar arteries. At operation it was evident that the aneurysm was a dissecting one of the vertebral artery. The proximal portion of the intracranial vertebral artery was clipped. The patient survived without any attributable neurological deficit. A review of the relevant literature is presented.
