Note.—A1 indicates A1 segment of the anterior cerebral artery; A-com, anterior communicating artery; ACA, the anterior cerebral artery; IC-PC, internal carotid-posterior communicating artery; M1–M2, M1–M2 segment of the middle cerebral artery; BA, basilar artery; BA-SCA, basilar-superior cerebellar artery; clip, clipping; wrap, wrapping; coil, coil embolization.
* Grade 2, provided further information that was helpful for surgery or embolization; grade 1, provided further information, but not helpful for surgery or embolization; grade 0, provided no further information. Reasons affecting treatment: (a) valuable information about whether treatment can be performed; (b) critical information about what treatment should be chosen when treatment can be performed; and (c) helpful information about manipulations of the aneurysm and adjacent arteries during surgery or endovascular treatment.
