[Comparative studies on early and late operations in aneurysm surgery]

In a five years period from January 1979 to December 1983 241 patients with angiographically verified aneurysms underwent operative treatment in the Department of Neurosurgery at Hannover Medical School. The final results six months after surgery are presented with special regard to the following subjects: preoperative grading (Hunt and Hess scale) and postoperative outcome (Glasgow Outcome Score) timing of surgery: early surgery within 72 hours (88 patients) versus delayed surgery (153 patients) incidence of rebleeding outcome of patients with space occupying intracerebral hemorrhage due to ruptured aneurysms.
