In a retrospective study the prognosis of acute subdural hematoma was
considered with reference to the data of 255 patients who underwent su
rgery because of acute subdural hematoma during a period of 10 years i
n the Department of Neurosurgery of the Landesnervenklinik in Salzburg
. The mortality rate was 43.5%, and 21.6% had a full functional recove
ry. The findings of the study confirm that the preoperative neurologic
al condition, the age, the kind of accident sustained and the extent o
f concomitant brain injury influence on the prognosis decisively.
