OBJECTIVE: Some studies have investigated the relationship between anatomic location and outcome in patients with cerebellar hemorrhage (CH), but not as yet the relationship between location of CH, as categorized according to vascular territory, and outcome. Furthermore, other studies have shown that taking antithrombotics was related to having CH; however, there have been no studies assessing the relationship between antithrombotics and the location of CH. The aim of this study was to determine whether the outcome of patients with CH at 1-year after onset differed depending on antithrombotic use and lesion location. METHODS: A retrospective, single-institution study involving 53 patients with CH was conducted. Location of the CH, categorized by vascular territory, was classified as either superior cerebellar artery hemorrhage (SCAH), anterior inferior cerebellar artery hemorrhage, or posterior inferior cerebellar artery hemorrhage. Outcome was evaluated using the modified Rankin scale (mRS) and mRS was divided into good (mRS ≤2) or poor (mRS ≥3). RESULTS: Thirty-four patients had SCAH, 5 had anterior inferior cerebellar artery hemorrhage, and 14 had posterior inferior cerebellar artery hemorrhage. Patients with poor outcome had higher proportions of Glasgow coma scale score ≤8, SCAH, intraventricular bleeding, hydrocephalus, and maximal transverse diameter ≥30 mm by univariate analysis. After multivariate analysis, Glasgow coma scale score ≤8 and SCAH showed a significant association with poor outcome. CONCLUSIONS: Outcome at 1-year after onset differed by location of the CH lesion as categorized according to vascular territory. SCAH was related to poor outcome by a larger maximal transverse diameter of hematoma and hydrocephalus.
