Obliteration of bilateral dissecting aneurysms of the vertebral arteries following repeated subarachnoid hemorrhage: a case report.

Abstract:

:A 51-year-old man presented with loss of consciousness when he underwent urological examination at another hospital. CT scans showed subarachnoid hemorrhage, and cerebral angiography showed bilateral dissecting aneurysms of the vertebral arteries. Following ventricular drainage, the lesion was managed conservatively with blood pressure control but again ruptured on day 8. Cerebral angiography revealed narrowing of both the dissecting aneurysms. On day 11, the right vertebral artery had been spontaneously obliterated and the right dissecting aneurysm was filled in a retrograde fashion via the left vertebral artery. Proximal occlusion of the right vertebral artery was performed to prevent recanalization. Two months later, cerebral angiography revealed that both vertebral arteries were obliterated and the basilar artery and right posterior inferior cerebellar artery were filled via the right posterior communicating artery. The present case demonstrated that the hemodynamic status of bilateral dissecting aneurysms of the vertebral artery changed variably indicating the necessity of careful angiographic observation.
