Cerebral venous pressure during actively induced hypertension and hypercapnia in cats

Abstract

Superior sagittal sinus pressure, intracranlal pressure and arterial pressure were recorded in an experimental series on 10 cats. During drug-induced, serere, acute arterial hypertension and parallel hypercapnia, venous pressure could exceed intracranial pressure in both the supra- and infratentorial compartment. From these data it is concluded that cerebral renous pressure during acute arterial hypertension may contribute to protein extravasation at the postcapillary-venular lerel. © 1980 American Heart Association, Inc.
