Description
Background The purpose of this study is to determine whether intraventricular hemorrhage (IVH) exerts a ‘‘decompressive’’ effect that limits intracerebral hemorrhage (ICH) enlargement. Methods Retrospective review of patients with spontaneous supratentorial ICH diagnosed within 6 h of onset, who underwent follow-up head CT approximately 48 h later. Digital imaging analysis of CT scans was performed to compare hematoma volume changes between patients with and without IVH. Hemorrhage locations were classified as paraventricular (PV) or non-PV. Regression analyses were employed to identify predictors of IVH, hematoma expansion, and mortality. Results Of the 70 patients included 57% developed IVH, 85% of which occurred before initial CT. 71% of PV hemorrhages developed IVH, all before initial CT, and 48% of non-PV hemorrhages developed IVH, 29% of which occurred after initial CT. IVH was associated with PV location (P = 0.04), and among IVH patients PV location was associated with early IVH (P = 0.003). Predictors of mortality included age (P = 0.037), initial hematoma volume (P < 0.04), absolute volume change (P = 0.01), and final hematoma volume (P < 0.001). Variables predicting IVH included PV location (P < 0.0001), larger initial hematoma volume (P = 0.002), and greater absolute volume increase (P = 0.01). Hematoma expansion was greatest for non-PV with IVH (P = 0.08), and graphic inspection suggested that ICH volume tended to decrease with PV location and increase with IVH. Final hematoma volume was associated with initial volume (P < 0.0001), non-PV location (P = 0.02), and IVH (P = 0.04). Conclusions IVH was not associated with less hematoma volume expansion, and for non-PV hemorrhages IVH was linked to greater volume increase
