回顾性分析了2004-08/2005-09解放军总医院神经外科应用Dexotroscope计划系统进行术前模拟的30例患者的资料,其中基底动脉瘤2例,大脑后动脉瘤1例,眼动脉瘤3例,大脑中☆动脉瘤2例,大脑前动脉瘤1例,寰枕畸形7例,脑膜瘤4例,神经鞘瘤5例,深部胶质瘤5例。将所有患者术前CT,MRI扫描的原始资料直接输入Dexotroscope计划系统的工作站,进行重建、模拟、分割等处理,并模拟手术全过程。结果手术中所见病变与周边神经、血管、颅骨的关系与手术前模拟完全符合;动脉瘤夹闭时间从2004-01/07未使用模拟系统前的(37.60±13.43)min降低为(23.51±7.62)min,齿状突磨除时间从模拟前的81min缩短至50min左右;术后3个月Karnofsky评分达88.7分,无死亡病例。提示应用Dexotroscope计划系统进行术前模拟可以制定精确而详细的手术计划,提前了解手术的难易程度,缩短手术时间。
The data of 30 patients who underwent preoperative simulation using the Dexotroscope planning system from Department of Neurosurgery, People’s Liberation Army General Hospital from August 2004 to September 2005 were retrospectively analyzed. Among them, 2 were basilar artery aneurysm, 1 posterior cerebral artery aneurysm, 3 eye aneurysm , 2 aneurysms in the brain, 1 anterior cerebral aneurysm, 7 atlanto-occipital deformities, 4 meningioma, 5 schwannomas and 5 deep gliomas. The raw data of preoperative CT and MRI scan of all patients were directly input to the workstation of Dexotroscope planning system for reconstruction, simulation and segmentation, and the whole process of operation was simulated. Results The relationship between the lesions and peripheral nerves, blood vessels and skull was completely consistent with the preoperative simulation. The aneurysm clipping time was reduced from (37.60 ± 13.43) min to (23.51 ± 7.62) min. The time of odontotomy was shortened from 81 min before simulation to about 50 min. The Karnofsky score reached 88.7 at 3 months after operation, with no deaths. Tips Dexotroscope planning system preoperative simulation can be used to develop accurate and detailed surgical plans, advance understanding of the ease of surgery, shorten the operation time.
