Note.—ACA = anterior cerebral artery, BA = basilar artery, MCA = middle cerebral artery, NA = not applicable, PCA = posterior cerebral artery, Vert = vertebral artery.
* Treatment was aborted as a result of sustained elevated ICP.
† ICP was transiently elevated but returned to baseline with opening of the ventriculostomy drain.
