Acute subdural hematoma associated with nontraumatic aneurysm rupture.

Five cases of subdural hematoma due to aneurysm rupture and their surgical treatment are reviewed. One patient recovered completely, one was severely disabled and 3 patients died. The literature regarding subdural hematomas associated with nontraumatic aneurysm rupture is reviewed and our therapeutical strategy is discussed. We conclude that severe neurological deficit and uncal herniation can be reversible if surgery is performed early.
