目的：2003年国际蛛网膜下腔动脉瘤试验（ISAT）结果的发布引起了颅内动脉瘤破裂管理模式的转变。目前显微手术夹闭的病例通常是不适合栓塞的动脉瘤，有时复杂且困难。我们设计了一个创新的应用程序的手术规划和培训开颅手术和显微手术夹持颅内动脉瘤在立体虚拟现实environment.Method：患者特定的DICOM数据的计算机断层扫描血管造影的颅内循环和头骨被转移到工作站（Dextroscope，体积互动Pte.，Ltd.）。将动脉瘤夹数据库加载到患者数据集中。结果：通过虚拟头部定位和开颅手术模拟了显微图像的可视化。可根据应用角度进行夹片选择。这使得外科医生看到的暴露和闭塞的动脉瘤的程度与不同的角度approach.Conclusion：虚拟开颅手术和显微手术夹应用程序模拟手术环境中遇到的。它在神经外科培训中的作用令人鼓舞，应进一步发展。
Objective: The release of results of the International Subarachnoid Aneurysm Trial (ISAT) in 2003 caused a shift in the paradigm of management of ruptured intracranial aneurysm. The microsurgical clipping cases today are usually aneurysms that are not suitable for embolization, at times complex and difficult. We devised an innovative application of operative planning and training for craniotomy and microsurgical clipping of intracranial aneurysm in a stereoscopic virtual reality environment.Method: Patient-specific DICOM data of computed tomographic angiography of the intracranial circulation and skull were transferred into the workstation (Dextroscope, Volume Interactions Pte., Ltd.). An aneurysm clip database was loaded into the patient dataset. 3D volume rendering was followed by data coregistration and fusion.Result: Virtual head positioning and craniotomy were carried out to simulate the microscopic visualization. Clip selection could be carried out with reference to the angle of application. This allows the surgeon to see the exposure and degree of obliteration of an aneurysm with the different angles of approach.Conclusion: The virtual craniotomy and microsurgical clipping application simulated the operative environment encountered. Its role in neurosurgical training was encouraging and should be further developed.
