[Reversed circulation as a possible method of preventing intra-cerebral hemorrhages (experimental study)].
Possibilities of reversed cerebral circulation, with arterial blood coming to cerebral tissue through the venous network and venous blood going through the arteries, were examined in acute and chronic experiments in dogs. Arterial blood pressure in cephalic veins reached 70-120 mm Hg, venous blood pressure in the circle of Willis was 5-35 mm Hg. Liquor pressure was never beyond 20-35 mm Hg. The EEG and reflex responses of the cerebral trunk were maintained for scores of minutes under acute experiment. Animals, surviving after prolonged arterialization of the cerebral venous network in chronic experiments (3-4 days), showed no central nervous or behavior disorders.
