Abstract：Objective To perform multimodal imaging-based digital three-dimensional reconstruction of a hyperten-sive basal ganglia hematoma model and its adjacent anatomical structures,and to simulate the process of neuroendoscopic hema-toma evacuation using virtual simulation technology based on the three-dimensional visual model.This aims to provide a novel approach for learning neuroendoscopic hematoma evacuation,enhancing the understanding of the relevant anatomical structures of hypertensive basal ganglia hemorrhage and the procedural workflow of neuroendoscopic hematoma removal.Methods Imag-ing data from a patient with hypertensive left basal ganglia hemorrhage admitted to the Department of Neurosurgery,The Second People's Hospital of Anhui Province,were collected.Using the post-processing capabilities of the open-source 3D Slicer software,structures including the hematoma,arterial system,venous system,skull,brain tissue,and skin were reconstructed sequentially.Virtual simulation technology was employed to simulate the neuroendoscopic hematoma evacuation procedure.Results The hematoma model and its adjacent anatomical structures were successfully reconstructed.By adjusting color and transparency combinations of the models,the relevant structures were effectively displayed.Virtual simulation of the surgical procedure was performed,dynamically demonstrating the puncture process of a virtual hematoma puncture needle,illustrating the sequential pas-sage of the virtual neuroendoscopic working channel through anatomical structures and their spatial relationships,and simulating hematoma evacuation.Conclusion The open-source 3D Slicer software can be utilized to reconstruct a three-dimensional model of hypertensive basal ganglia hemorrhage.Combined with virtual simulation technology,it can visually demonstrate the process of neuroendoscopic hematoma evacuation,including real-time display of the puncture position,angle,depth,and optimal trajectory of the virtual working channel.This provides a novel and effective tool for learning neuroendoscopic hematoma evacuation.
