Abstract
In the last ten years the microneurosurgical treatment of ruptured cerebral aneurysm has become safer, with an operative mortality of 5–7% (Yaşargil 1984). The aim of early surgery within 72 hours after subarachnoid hemorrhage (SAH) is to prevent rebleeding and to be able to start a postoperative medical treatment for vasospasm with hypertonia and/or hypervolemia. The mortality is mainly due to delayed ischemic deficits (DID) with 27% due to vasospasm (Kassell 1984). Because the real cause of vasospasm is not yet known, all therapeutic measures are symptomolytic: either the perfusion pressure of the brain is increased (hypertonia) or the resistance is decreased by preventing the arterial walls from contracting (calcium channel blocker nimodipine) (Allen 1983).
