  • Title: Regional cerebral blood flow in the acute stage of experimentally induced subarachnoid hemorrhage.
    Author: Umansky F, Kaspi T, Shalit MN.
    Journal: J Neurosurg; 1983 Feb; 58(2):210-6. PubMed ID: 6848678.
    Abstract:
    Subarachnoid hemorrhage (SAH) was induced in 13 adult mongrel cats by a slow injection of fresh autogenous blood into the cisterna magna. Serial determinations of regional cerebral blood flow (rCBF) in the cortex and deep-seated areas (internal capsule, thalamus, and caudate nucleus) were made during the following 2 hours, while intracranial pressure (ICP) was maintained at normal values. A decrease in rCBF was observed in all the areas examined. This reduction followed a characteristic triphasic pattern with an initial steep decline immediately after the SAH. The clinical implications of these findings are discussed.
