BACKGROUND AND PURPOSE: To determine whether status of dominant vertebral artery could affect clinical outcome in @entity1 with symptomatic basilar @entity432 (BAO). METHODS: We reviewed @entity1 with symptomatic BAO who underwent endovascular treatment at the institute between January 2007 and July 2014. @entity1 were categorized into 2 groups according to functional outcome and baseline characteristics, treatment related factors were compared. Variables including clinical and imaging parameters were also compared according to the dominant V1 lesion. RESULTS: Fifty-nine of 101 @entity1 underwent endovascular treatment and 23 @entity1 (39.0%) showed favorable outcome (modified Rankin score <= 3 at 3 month). Younger age, male sex, lower baseline NIHSS score, higher PC-ASPECTS, absence of hemorrhagic transformation, shorter procedure time, and complete recanalization were associated with favorable outcome. Procedure time tended to be longer in @entity1 with dominant V1 lesion (130.0; range, 105.0-179.0 vs. 101.5; range, 48.0-138.0, P=0.05). Among @entity1 with @entity455 ( @entity455 ), higher initial NIHSS, and clinical manifestation of decreased mental status were significantly associated with dominant V1 lesion. Endovascular procedure time tended to be longer, @entity432 tended to be more frequent, and proportion of the @entity1 with complete recanalization tended to be less in @entity1 with dominant V1 lesion. Poor outcome tended to be more frequent in dominant V1 lesion with @entity455 (88.9% vs. 42.9%, P=0.05). These findings were comparable in @entity1 who underwent mechanical thrombectomy. CONCLUSION: Dominant V1 steno-occlusion may be associated with poor functional outcome in @entity1 with the symptomatic BAO. Status of dominant VA and various treatment strategy should be considered when performing endovascular treatment for recanalization in @entity1 with symptomatic BAO.
