Long-term prognosis in surgically treated intracranial aneurysms

Abstract

An evaluation of long-term results following aneurysm surgery is presented. Five different outcome measures are used in a population of 204 survivors followed for a minimum of 18 months and a maximum of 5 1/2 years. The findings show that 1) results vary dependeing on the outcome measure used, and 2) outcome can be predicted with a considerable degree of accuracy using preoperative and early postoperative variables. The most important predictive factors were postoperative vasospasm, age, systemic blood pressure on admission, and preoperative neurological status. The results are compared with a control group.
