Early surgery for posterior circulation aneurysms following subarachnoid haemorrhage.
A retrospective analysis of 32 patients with posterior circulation aneurysms operated on within three days of subarachnoid haemorrhage is presented. The cases were treated at two Australian neurosurgery units over a five year period (1988-1992), both units having a policy of treating patients of all grades and all ages with early surgery. No patients suffered rebleeding. Five patients developed clinical vasopasm. Twenty-four patients (75%) had a good outcome (Glasgow Outcome Score 1-2), three had a poor outcome (GOS 3), and five died (16%). Of the five deaths, three presented as Hunt and Hess grade V. The results are considered in detail and the literature regarding the timing of surgery for posterior circulation aneurysms is reviewed.
