Management mortality and the timing of surgery for supratentorial aneurysms

Abstract
A retrospective analysis of 224 patients with a ruptured supratentorial aneurysm, admitted to the care of 1 of 6 neurosurgeons on the day of or the day following their subarachnoid hemorrhage, was carried out. Both postoperative and management mortality rates were calculated by the grade of the patient on admission. There were no statistically significant differences in postoperative and management mortality rates when patients were categorized by time of operation, except for the increased management mortality for Grade 3 and 4 patients who were operated on late.
