术中超声在脑胶质瘤外科治疗中的应用

目的探讨术中超声在脑胶质瘤外科治疗的应用价值。方法30例幕上原发性胶质瘤显微手术在术中采用实时超声定位肿瘤，确定边界和切除程度。结果所有30例胶质瘤的回声特性不同于正常脑组织，可被准确识别，实质性低级别胶质瘤以脑沟为边界，恶性胶质瘤最常见的回声表现是中心性坏死。所有肿瘤均在超声引导下获得全切除，只有2例患者术后出现轻度神经功能缺失。结论术中超声可为脑胶质瘤手术提供实时信息，使之获得准确和有效的外科治疗。

Application of intraoperative ultrasound in cerebral gliomas surgery

ObjectiveTo investigate the role of intraoperative ultrasound (IOUS) in the surgical treatment of cerebral gliomas.MethodsThirty patients with primary supratentorial gliomas underwent microsurgery guided by intraoperative real-time ultrasound, IOUS was utilized for localization and delineation of the tumor as well as determination of the extent of resection.ResultsAll of 30 lesions were accurately defined by IOUS due to the distinct echogenicity compared with the normal brain. Solid low grade gliomas tended to be well circumscribed with regular sulcus, while central necrosis was most commonly present with malignant gliomas. Complete tumor extirpation was achieved by IOUS guidance in this group. Two patients exhibited mild neurological deficit following the surgery.ConclusionIOUS may provide valuable real-time information and facilitate effectual surgery with accuracy for the cerebral gliomas.
