[Clinico-anatomical analysis of the causes of death in ruptures of intracranial arterial aneurysms].

Causes of lethal outcome in patients after subarachnoid hemorrhage due to cerebral aneurysm rupture were analysed. The major death cause in the operated patients was cerebral edema and dislocation, while in non-operated ones it was the penetration of blood into the ventricles of the brain. Cerebral edema and dislocation syndrome were mainly caused after surgery by ischemic changes in cerebral tissue. A relationship between the aneurysm localization and the extent of subarachnoid hemorrhage was revealed as well as between the hematoma localization and incidence of hemorrhage into the ventricles of the brain.
