title: Hypotensive hemorrhagic necrosis in basal ganglia and brainstem.
abstract: Hypotensive hemorrhagic necrosis of the basal ganglia and brainstem has only occasionally been described. Three such cases are reported. Cardiac arrest had occurred in all cases, and it took at least 1 hour to restore adequate circulation. The patients remained comatose for 2 days to 2 weeks until death. Persistent hypotension causing ischemia in the distribution of deep perforating arteries is considered to have been the key underlying mechanism. Hemorrhage is thought to have been caused by extravasation of red blood cells through damaged blood vessels.
