Subarachnoid blood was actively removed in the acute stage of Subarachnoid hemorrhage (SAH; scavenger surgery) after the clipping of aneurysms in 109 patients with ruptured cerebral aneurysms. The effect on prevention of vasospasm was evaluated to compare the results of 89 conventional acute surgeries without removal of the blood. Both the incidence of ischemic complication and mortality were lower in the “scavenger surgery” group than in the “conventional surgery” group in patients with high SAH scores on CT. Twothirds of those patients with severe SAH were freed from cerebral infarction and half of the patients had no neurological deficits.
