脑胶质瘤术中超声应用价值

Application Value of Intraoperative Ultrasound in Brain Gliomas Resection

目的:探讨术中超声技术在脑胶质瘤手术中的应用价值。方法:脑胶质瘤50例经术前CT和(或)MRI确诊行手术治疗,为准确定位和彻底清除肿瘤,术中行超声检查,并监测手术全过程。结果:脑胶质瘤50例术中,超声均成功引导术者在术中准确定位病灶,并提供最佳手术路径。术中超声检查结果:高级别胶质瘤超声表现为形态不规则,边缘不整齐,内部回声呈等至高回声信号。部分病例可见大小不等的多发囊性回声,病变外周可见稍高回声水肿带。低级别胶质瘤表现为均匀稍强回声信号,与正常脑组织分界较清晰。结论:术中超声能提供实时的术中影像信息,准确识别、定位病灶,在手术过程中可以反复操作,有效地保护病灶周围重要结构及大血管,提高手术全切率,减少术后并发症。

Objectives： To monitor the whole process of microsurgical resection of glioma by IOUS and to study the application value of intraoperative ultrasound （intraoperative ultrasound, IOUS） in resection of glioma. Methods： During March 2009 and November 2013, IOUS was used to check 50 patients who were diagonised as glioma by CT and / or MR before the operation treatment in our hospital neurosurgical department and to monitor the surgical process. Results：50 cases could clearly showed the images of lesion. High grade glioma ultrasound showed irregular shape and irregular edge. The internal echo displayed the echo signal that was equal to high in form, in some cases showed multiple cystic echo of varying sizes, and in the outer periphery of the lesion showed slightly visible echo edema. Low-grade glimas showed slightly higher homogeneous echo signals and had a clear demarcation with normal brain tissue. Conclusion： Intraoperative ultrasound can provide the image information in real time operation, accurate identification and location of lesions, make it possible to repeat the operation procedures in the operation process, effectively protect the surrounding important structures and large blood vessels, improve the operation resection rate, and reduce the postoperative complications.
