An indicates aneurysm; BAT, basilar trunk; CR, clip reconstruction; DB, distal bypass; IPO, immediate proximal occlusion; mRS, modified Rankin Scale; Pcom, posterior communicating artery; RPO, remote proximal occlusion; Tx, treatment; VBJ, vertebrobasilar junction.
aFor untreated patients, mRS was obtained at 3 mo after the initial diagnosis.
