目的 探讨术中超声在颅内病变显微手术中的应用.方法 显微神经外科手术治疗颅内病变21例,采用术中超声对病变所在位置进行扫查并准确定位,判断病变的性质,观察病变的边界、与周围组织的关系,彩色多普勒观察病变内部及周围的血流情况,测量病变的大小、范围、距脑膜的距离.结果 全部病例在术中超声引导下准确定位,并通过显微外科手术全部切除病灶.结论 术中超声可以在手术中灵活、实时、准确地定位病变,缩短了手术时间,避免了不必要的正常脑组织损伤,保护了神经功能,提高了手术的安全性和治疗效果.%Objective To explore the application of intraoperative ultrasound in intracranial lesion microsurgery operation.Methods Twenty-one cases of intracranial lesions were treated by microneurosurgical operation.The intraoperative ultrasound was adopted to scan and accurately locate the lesion position,judge the lesion character and observe the relation between the lesion border with the surrounding tissues.The lesion inside and surrounding blood flow situation was observed by color Doppler ultrasound.The lesion size,range and distance from the meninges were measured.Results All cases were accurately positioned under the ultrasound guidance,and all the lesions were removed by microsurgery.Conclusion Intraoperative ultrasound flexibly,real-time and accurately localizes the lesion,shortens the operation time,avoids unnecessary normal brain tissue damage,protects the nerve function,and improves the safety and efficacy of operation.
