Results of delayed operations for ruptured supratentorial aneurysms in 22 consecutive patients.

Twenty-two patients with surgically treated ruptured aneurysms were reviewed retrospectively regarding age, sex, aneurysm site distribution, clinical grading, rebleeding, timing of surgery and long term results. The most common aneurysm site was in the Anterior Communicating artery (44%). The mean time between aneurysmal subarachnoid hemorrhage and surgery was 20 days. There were 4 cases with intraoperative rupture. The outcome was favorable in 63.6 per cent after a mean follow-up of 21 months. The overall mortality rate was 22.7 per cent. The results may be improved by an early, well planned operation.
