“…38 Thereafter, CBF decreased in most studies, irrespective of whether a concomitant VS reaction of the intracranial vessels was observed on angiography or not. 28,29,32,33,38,40,44 Furthermore, neurologic outcome was more related to rCBF than to the presence of VS in large cerebral vessels as detected angiographically or by means of TCD. 15,30,32,36 Correlation Between rCBF and VS Induction of SAH in our animals produced a mild to moderate VS of the basilar artery, but resulted in a marked decrease in rCBF in each brain region examined.…”
