BACKGROUND/OBJECTIVE Infratentorial intracerebral hemorrhage (ICH) is associated with worse prognosis than supratentorial ICH; however, infratentorial ICH is often excluded or underrepresented in clinical trials of ICH. We sought to evaluate the natural history of infratentorial ICH stratified by brainstem or cerebellar location using a prospective observational study inclusive of all spontaneous ICH. METHODS Using a prospective, single center cohort of patients with spontaneous ICH between 2008-2019, we conducted a descriptive analysis of baseline demographics, severity of injury scores, and long-term functional outcomes of infratentorial ICH stratified by cerebellar or brainstem location. RESULTS Infratentorial ICH occurred in 82 (13%) of 632 patients in our ICH cohort. Among infratentorial ICH, cerebellar ICH occurred in 45 (55%) and brainstem ICH occurred in 37 (45%). Compared to cerebellar ICH, patients with brainstem ICH had significantly worse severity of injury scores, including lower admission Glasgow Coma Scale (median 14 [7.0 - 15.0] versus 4 [3.0 - 8.0], respectively; P < 0.001) and higher ICH Score (median 2 [1.0 - 3.0] versus 3 [2.75 - 4.0], respectively; P =  0.02). Patients with cerebellar ICH were more likely to be discharged home or to acute rehabilitation (OR 4.8, 95% CI 1.8 - 12.8) but there was no difference in in-hospital mortality (OR 0.4, 95% CI 0.1 - 1.1, P =  0.08) or cause of death (P =  0.5). Modified Rankin Scale scores at 3 months were significantly better in patients with cerebellar ICH compared to brainstem ICH (median 3.5 [1.8 - 6.0] versus median 6 [5.0 - 6.0], P =  0.03). CONCLUSIONS Location of infratentorial ICH is an important determinant of admission severity and clinical outcome in unselected patients with ICH. Patients with cerebellar ICH have less severe symptoms at presentation and more favorable functional outcomes compared to patients with brainstem ICH.

幕下脑出血的自然史:具有不同表现和结果的两个亚组。

背景/目的 幕下脑出血 (ICH) 的预后比幕上 ICH 更差。然而,幕下 ICH 在 ICH 的临床试验中经常被排除或代表性不足。我们试图使用一项包括所有自发性 ICH 的前瞻性观察研究来评估按脑干或小脑位置分层的幕下 ICH 的自然病程。方法 使用 2008-2019 年间自发性 ICH 患者的前瞻性单中心队列,我们​​对基线人口统计学、损伤评分的严重程度和按小脑或脑干位置分层的幕下 ICH 的长期功能结果进行了描述性分析。结果 在我们的 ICH 队列中,632 名患者中有 82 名 (13%) 发生幕下 ICH。在幕下 ICH 中,45 例 (55%) 发生小脑 ICH,37 例 (45%) 发生脑干 ICH。与小脑 ICH 相比,脑干 ICH 患者的损伤严重程度评分明显更差,包括入院时格拉斯哥昏迷量表较低(中位数分别为 14 [7.0 - 15.0] 对 4 [3.0 - 8.0];P < 0.001)和更高的 ICH 评分(中位数分别为 2 [1.0 - 3.0] 和 3 [2.75 - 4.0];P = 0.02)。小脑 ICH 患者更有可能出院回家或进行急性康复(OR 4.8,95% CI 1.8 - 12.8),但院内死亡率没有差异(OR 0.4,95% CI 0.1 - 1.1,P = 0.08 ) 或死因 (P = 0.5)。与脑干 ICH 相比,小脑 ICH 患者 3 个月时的改良 Rankin 量表评分显着更好(中位数 3.5 [1.8 - 6.0] 与中位数 6 [5.0 - 6.0],P = 0.03)。结论 在未经选择的 ICH 患者中,幕下 ICH 的位置是入院严重程度和临床结果的重要决定因素。与脑干 ICH 患者相比,小脑 ICH 患者在就诊时症状较轻,功能结局更佳。
