AbstractIntraventricular hemorrhage is associated with poor functional outcomes in patients with intracerebral hemorrhage (ICH). We aimed to investigate the association between intraventricular hemorrhage and early hematoma expansion in patients with ICH. Patients with ICH who underwent a baseline CT scan within six hours after onset of symptoms were included. The follow-up CT scan was performed within 24 hours after the baseline CT scan. Univariate and multivariable logistic regression were used to assess the relationship between presence of intraventricular hemorrhage and early hematoma expansion. A total of 160 patients were included in the study. Significant hematoma growth was observed in 52 (32.5%) patients presenting within six hours after onset of symptoms. Intraventricular hemorrhage was observed in 66 (41.25%) patients with ICH. Multivariate analyses demonstrated that a short time from onset to baseline CT scan, the initial hematoma volume, and the presence of intraventricular hemorrhage on follow-up CT scan were independently associated with hematoma enlargement. The presence of intraventricular hemorrhage on follow-up CT scan can be associated with hematoma expansion in patients with ICH.
