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.
