Abstract

Abstract A total of 153 consecutive patients with proven aneurysmal subarachnoid hemorrhages (SAHs) admitted immediately after diagnosis regardless of clinical condition were managed according to the same protocol. The initial evaluation included computed tomography (CT), transcranial Doppler ultrasound (TCD), angiography-CT, and/or angiography. Intravenous nimodipine (2 mg/hour) was started after confirmation of the diagnosis. The timing of operation was determined individually according to age, clinical course, and CT and TCD findings. Twenty-one Grade V patients treated with intensive care and ventriculostomy died or did not improve within 24 hours after SAH. Three patients with life-threatening intracerebral hematomas underwent emergency operation. Operation was early in 55 good risk patients and late in 57 patients because of poor initial grade, late admission, or logistic reasons. Seventeen patients had no operation because of old age, persistent poor clinical condition, medical complication, or lethal rebleeding before operation. In the total series, 90 patients (59%) made a full recovery, the overall morbidity rate was 14% (21 of 153 cases), and the mortality rate was 27% (42 of 153). Postoperative mortality including emergency evacuation of hematomas was 7.8% and mortality after elective operation was 6.2%. The causes of disability and death were the initial effect of the hemorrhage in 25 patients (16.3%), rebleeding in 15 (9.8%), delayed cerebral infarction in 8 (5.2%), surgical complications in 7 (4.5%), hydrocephalus in 4 (2.6%), and medical complications in 4 (2.6%).
