中文摘要：

目的探讨术中超声辅助神经导航系统在颅内病变切除术中的临床价值。方法回顾性分析2010年1月至2011年7月经术中超声辅助神经导航手术的42例患者的临床资料，重点关注神经外科导航的脑移位、超声图像的价值和手术操作的技巧。结果42例超声辅助导航定位病灶准确性100％。术中超声能纠正单纯神经导航手术中所产生的脑移位。经术后影像学证实病变全切除37例，大部分切除4例，部分切除1例。术后偏瘫1例，视野缺损1例，无死亡。结论术中超声可以纠正脑移位，对脑深部病灶寻找和定位有很高价值，为术者选择手术人路和切开皮层等方面提供了明确且重要的价值，有助于准确定位病灶并提高手术切除率。

英文摘要：

Objective To discuss the clinical value of intraoperative ultrasonography added with neuronavigation in intracranial lesions resection. Methods The clinical materials of 42 cases with intracranial lesions which were resected by intraoperative uhrasonography added with neuronavigation between January 2010 to July 2011 were retrospectively analysised. There were 30 male and 12 female, aged from 13 to 70 years old, with a mean age of 42. 9 years old. The brain shift of neuronavigation, the value of ultrasonic image and operation skills were focused on. Results The accuracy of localization was 100% in 42 cases with intracranial lesions which were resected by intraoperative ultrasonography added with neuronavigation. Intraoperative ultrasonography can correct the brain shift of neuronavigation during the operation. Total removal of the lesions was achieved in 37 cases, subtotal resection in 4 cases and partial resction in 1 case. Hemiplegia happened in 1 case and visual field defects happened in 1 case postoperatively. No death occurred. Conclusions Intraoperative ultrasonography is important to the correct of brain shift and has high value in finding and localizing the deep intracranial lesions. It has clear and important value to the choice of operation approach and incising coetex. Intraoperative ultrasonography added with neuronavigation can help surgeon locating the lesions and improve resction rate.
