摘要

背景:虚拟内窥镜(VE)是一种新兴的成像技术。应用于神经内窥镜检查,它允许术前模拟程序和评估个别脑室解剖在选定的情况下。与神经导航和实时术中成像一起,VE有望提高神经内镜手术的安全性和有效性。患者和方法:在2003年4月至2004年2月期间,随机选择13例接受内窥镜手术的患者进行VE模拟。病理实体包括导水管狭窄4例,鞍上蛛网膜囊肿4例,后第三脑室肿瘤2例,胶质囊肿1例,脉络膜丛增生1例,室间隔所致多室脑积水1例。8例患者术前完成VE, 5例患者术后完成VE, 4例患者使用神经导航成像计划数据集,1例患者使用术后影像学研究。在1.5 tge Genesis SIGNA MR扫描仪上获取T(1)加权三维图像集,并使用通用电气Navigator软件进行VE重建。将VE图像与内镜手术过程中获得的真实图像进行比较,并评估其对手术入路规划的影响。结果:13例患者均成功实施VE。所有病例的主要神经解剖学参考结构均易于识别。膜性结构,如第三脑室底变薄或囊肿壁仅在46%的病例中可识别。在6例(46%)病例中,VE显示了与内窥镜手术相关的解剖变异和细节,这些在常规MR图像上未被识别。结论:VE已被证明是神经内镜手术术前规划的重要辅助手段,建议常规应用。

Virtual simulation of neuroendoscopic procedures: early clinical experience with ventricular lesions.

Background: Virtual endoscopy (VE) is a new and promising imaging technology. Applied to neuroendoscopy it allows preoperative simulation of a procedure and evaluation of the individual intraventricular anatomy in selected cases. Along with neuronavigation and real time intraoperative imaging, VE is expected to improve the safety and efficacy of neuroendoscopic procedures.

Patients and methods: Between April 2003 and February 2004 VE simulation was performed in 13 randomly selected patients subjected to endoscopic procedures. Pathological entities included 4 cases with aqueduct stenosis, 4 with suprasellar arachnoid cysts, 2 tumors of the posterior third ventricle, 1 colloid cyst, 1 hyperplasia of the choroid plexus and 1 case with multiloculated hydrocephalus due to intraventricular septations. In 8 patients VE was accomplished preoperatively, in another 5 it was done after the operation, using data sets from neuronavigation imaging planning in 4 patients, and in one case using postoperative imaging studies. T (1)-weighted 3D image sets were acquired on a 1.5 T GE Genesis SIGNA MR scanner and VE reconstruction was performed using the General Electric Navigator software. The VE images were compared with the real images obtained during the endoscopic procedures and evaluated for their impact on the planning of the operative approach.

Results: VE implementation succeeded in all 13 patients. Major neuroanatomic reference structures were easily recognizable in all cases. Membranous structures such as the thinned floor of the third ventricle or cyst walls were identifiable in only 46 % of the cases. In 6 cases (46 %) VE showed anatomical variants and details relevant for the endoscopic procedure that were not identified on conventional MR images.

Conclusions: VE has proved to be an important adjunct to the preoperative planning of neuroendoscopic procedures and its routine application is suggested.
