  • Abstract
  • Look Inside

7 Patients in a vegetative state were studiedfor regional cerebral blood flow (rCBF) and cerebralmetabolism. rCBF in such patients was low com-pared to posttraumatic syndrome, and cerebro-vascular resistance (CVR) was high. In thesepatients due to head injuries, rCBF was low andCVR was high in the affected side. There was adifference in the CO2 response of the cerebralvessels among the patients. These findings wereconsidered to be a result of the degeneration ofthe smooth muscle in the cerebral vessels. Dis-autoreguration of the cerebral blood flow was foundin these patients.

The existence of elasticity in the cerebral vesselswas examined by auto-blood pumping therapy inthe internal carotid artery. The patients nothaving laterality when examined neurologicallywere considered to have severe brain damage inthe dominant sphere.
