Total morbidity and mortality rates of patients with surgically treated intracranial aneurysms.

The authors report their recent experience in treating 80 patients with intracranial aneurysms. A total of 83 surgical procedures were performed with a surgical mortality of 4.8%. Fifty-six patients had suffered a subarachnoid hemorrhage. Total mortality for this group was 14.2% regardless of clinical grade. Early surgical intervention, meticulous preoperative monitoring, and control of circulatory dynamics were used to improve the perioperative morbidity and mortality rates. We believe that any major improvements in the outcome of patients with aneurysms will come from advances in perioperative management.
