Note:—R3 M indicates major recanalization; R3+, worse than previous R3 (ie, more contrast filling aneurysm sac); SC, superior cerebellar; S, small neck; W, wide neck; AcomA, anterior communicating artery; ICA, internal carotid artery; MCA, middle cerebral artery; PcomA, posterior communicating artery; PICA, posterior inferior cerebellar artery.
