【摘要】 目的：探讨颅内胶质瘤术中超声的使用及价值资料和方法：回顾性分析33例术中使用超声的颅内胶质瘤患者和39例未使用超声探查的胶质瘤患者的临床资料。将探头放在硬膜外、硬膜下、脑组织表面探查，并在肿瘤切除后的瘤腔进行探查，对肿瘤进行定位，确定肿瘤的位置、边界、周围血管等等，引导术者选择合适的手术入路，以最小的损伤而最大程度地切除肿瘤。统计分析术中超声组和非术中超声组的定位率、手术全切率和手术时间等。结果：通过术中超声，所有的病变均被准确定位，准确率达100%。使用术中超声明显提高了胶质瘤的全切率和缩短手术时间。低级别胶质瘤和高级别胶质瘤在超声图像上有不同的特征性表现。结论：术中超声具有低成本、准备时间短、方便快捷、实时监测、可重复和无辐射等优点。它是胶质瘤手术中的重要辅助工具，在胶质瘤定位和实时监测残余肿瘤方面具有重要的使用价值。它可以提高肿瘤的全切率，减少手术并发症，有效缩短手术时间。更多还原

【Abstract】 Objective: To investigate the use and value of intraoperative ultrasound guidance inintracranial glioma resectionMaterials and Methods: We retrospectively analyzed the clinical data of33patientswith intracranial glioma who used ultrasound to guide surgical margins and comparedthose of39patients without ultrasound guidance. The probe was placed on theepidural, subdural surface and brain tissue surface to explore the tumors and theresected tumor cavity was explored, to locate the tumor and determine the location,borders, peripheral blood vessels, etc., help the surgeon to select the best approach sothat maximum tumor resection was achieved with minimal damage. We statisticallyanalyzed and compared the positioning accuracy, curative resection rate and operativetime between intraoperative ultrasound group and non-intraoperative ultrasoundgroup.Results: All the lesions were accurately localized using the ultrasound guidance withan accuracy of100%. The use of intraoperative ultrasound significantly improved therate of curative resection of intracranial glioma and shortened the operation time. Theultrasound characteristics of low-grade gliomas were different from those ofhigh-grade gliomasConclusions: Intraoperative ultrasound has the advantage of low-cost, the relativelyshort time required for preparation, fast and convenient, real-time monitoring,repeatability, without radiation, etc. It is an important tool in glioma surgery, has greatvalue in glioma locating, real-time monitoring of residual tumor. It can improvecurative resection rate of the tumor, reduce surgical complications and effectivelyshorten the operation time.更多还原
