目的 利用Brain Lab整体超声导航实时监测并切除脑深部肿瘤,探讨术中超声结合导航在神经外科手术中的价值.方法 应用Brain Lab整体超声导航系统对30例脑深部肿瘤进行显微神经外科手术,结合导航图像,术中超声动态了解病变移位情况,实时显示病变边界,进行移位后病灶的全切除.结果 术中实时超声证实在30例导航手术过程中均有不同程度的病灶移位,在超声引导下,探寻残余肿瘤并在监测下进一步全切除,术后未出现明显的并发症.结论 术中整体超声导航不仅可以在移位情况下重新准确定位肿瘤边界,而且可以在实时超声监测下进一步切除肿瘤,缩短手术时间,增加了全切除率,提高了手术的安全性.

Objective To assess the value of real-time intraoperative neuronavigation integrated with ultrasound in the resection of deep-seated brain tumor. Methods Thirty patients with deep-seated brain tumor were treated with microneurosurgery guided with real-time ultrasound integrated with the Brain Lab IGSonic navigation. During the ultrasound based operation, the degree of brain shift and the tumor border was timely observed, and then the tumor was resected totally. Results Guiding with navigation integrated ultrasound, we noticed the brain shift with various degrees happening in 30 patients,and the border of tumor was exposed and the tumor was resected totally without serious complications.Conclusions Intraoperative ultrasound integrated with navigation is a reliable guidance which can accurately re-localize the border of deep-seated brain tumor even when the tumor is shifting, timely delineate the reformatted images from ultrasound and totally resectcd the tumor, thus decrease the surgical time and increase the safety of surgical procedure.
