Note:—VA indicates vertebral artery; Pre, precontrast; Post, postcontrast; BA, basilar artery; M1, horizontal segment of the MCA; M2, insular segment of the MCA; C2, C2 segment of the ICA; C4, C4 segment of the ICA;

^*, with contralateral VA occlusion;

^†, cross-flow via posterior communicating artery; –, vessel distal to the occlusion was not included in the scanning range.
