3D Slicer-Assisted Preoperative Planning Enhances Hematoma Evacuation in Stereotactic Aspiration for Intracerebral Hemorrhage.

Abstract

This study aims to assess whether preoperative hematoma reconstruction and precise volume calculation can improve the hematoma evacuation rate in patients with spontaneous intracerebral hemorrhage(sICH) undergoing stereotactic aspiration (SA). A retrospective analysis was conducted on patients with sICH who underwent SA from January 2021 to December 2023. Patients were divided into 2 groups based on the use of 3D Slicer for preoperative hematoma reconstruction and volume calculation. Propensity score matching (PSM) was applied to adjust for baseline differences between groups. Statistical analysis was performed to compare hematoma evacuation rate and residual hematoma volume. After PSM, the 3D Slicer group achieved a higher mean evacuation rate (70.9%) compared with the non-3D Slicer group (53.1%), with a median residual hematoma volume of 7.4 mL versus 15.3 mL, respectively. Preoperative hematoma reconstruction and volume calculation using 3D Slicer in patients with sICH undergoing SA significantly improves hematoma evacuation rate and reduces residual hematoma volume.
