术中超声在脑肿瘤切除术中应用与预后的关系

Application of intraoperative ultrasonography in the surgical treatment of brain tumors and its relation to the prognosis

目的采用术中超声观察颅脑肿瘤的超声图像特点,探讨其在神经外科手术中的应用价值与患者预后的关系。方法将45例脑肿瘤患者随机分为A、B两组,在显微外科手术基础上,A组23例颅脑肿瘤患者在手术中接受了术中超声检查,以确定肿瘤的位置、手术切除范围及切除术后是否有肿瘤残余,B组22例行常规手术,并比较两组之间的差异。结果术中超声能清晰地显示肿瘤的情况,经手术完整切除肿瘤。并发症无差异,神经功能废损、复发及预后之间差异有统计学意义(P<0.05)。结论术中超声作为一种实时、无创、简便的辅助检查方法 ,可帮助手术医师确定肿瘤的部位、边界及血流,能保护神经功能及降低手术并发症的发生,从而提高手术安全性及治疗效果。

Objective To evaluate the clinical value of intraoperative ultrasonography in the diagnosis,treatment and the relation to the prognosis of patients with brain tumors.Forty-five brain tumors patients were randomize divided into group A and group B.The microsurgery were utilized ordinarily in both groups.The intraoperative ultrasonography was performed in group A.The intraoperative ultrasonography were used to locate the intracranial neoplasms 23 patients of group A,confirm the range of resection,and detect whether there was any residual mass after the microsurgical resection of the tumor removal.In group B 22 cases received routine microsurgical treatment.The removal of tumor complication and outcomes were compared.The condition of the neoplasms were clearly revealed under intraoperative ultrasonography.All intracranial neoplasms in group A were completely remowed.And the operative complications didn＇t show significant statistical difference between two groups,There were significant statistical differences between the two groups in post-operative including neurological function damage,recurrence and prognosis（P0.05）.Intraoperative ultrasound is a real-time,noninvasive,and convenient approach to identify the location and boundary of the turners and evaluate blood flows of brain tumors.It can assist the docters to the protecting the neurological function and reducing the operative complications,therefore improre the safety and efficacy of the operations.
