Surgical treatment of arterial aneurysms of the vertebrobasilar circulation

Abstract

✓ Twenty patients with basilar bifurcation aneurysms and subarachnoid hemorrhage were treated surgically as a consecutive series irrespective of preoperative grading. There were six fatalities; eight of the survivors have done well while six are in poor condition. The authors also report a series of 13 surgical cases of posterior fossa aneurysm not located at the basilar bifurcation, three on the posterior cerebral artery, five on the basilar trunk, and five on the vertebral origin of the posterior inferior cerebellar artery. There were two operative deaths and one late death due to pulmonary embolism. The other 10 have had good results.
