Treatment of Anterior Communicating Aneurysms

Abstract

One method of treating ruptured anterior communicating aneurysms is presented. This permits early clipping through a bifrontal flap. Key branches of the circle of Willis are temporarily occluded by special removable clips before exposing and permanently clipping the aneurysm. This requires the use of hypothermia at 28'0. and other technical aids described. The risk of a fatal recurrent hemorrhage appears to be removed by this method with a reasonable operative mortality (5%) and morbidity (20%) that compare favorably with the mortality rate for un-operated patients of 34% or higher
