Ultrasound imaging has become a common method for evaluation of the central nervous system. In this report, we present our novel experience with ultrasonography monitoring conducted through a burr-hole for investigation of intracranial lesions. A portable ultrasound scanner and a small transducer with a straight, untapered head were used. After opening a standard burr-hole, the transducer was inserted through the burr-hole and the intracranial lesion was examined. Intraoperative ultrasonography provides immediate ongoing information about the anatomy and pathological lesions. Distance and trajectory to the best location for the catheter were determined and the catheter was inserted with ultrasound monitoring. The final position of the catheter placed accurately into the intended compartment of the ventricular system. No procedure related complication was noted and pitfalls were minimal. Furthermore, a postoperative CT scan was obtained in each case to confirm the appropriateness of the procedure with ultrasonography. In conclusion, intraoperative ultrasonography using a burr-hole transducer has proved useful in neurological surgery.
超声成像已成为评估中枢神经系统的常用方法。在本报告中，我们展示了通过骨孔进行超声监测以调查颅内病变的全新经验。使用了一台便携式超声扫描仪和一个头部笔直、无锥度的小型换能器。在开一个标准骨孔后，将换能器通过骨孔插入并检查颅内病变。术中超声检查可提供有关解剖结构和病理性病变的即时连续信息。确定了导管至最佳位置的距离和轨迹，并在超声监测下插入导管。导管最终准确放置在脑室系统的预定腔室中。未发现与手术相关的并发症，且失误极少。此外，每例患者术后均进行了CT扫描，以确认超声检查手术的适宜性。总之，使用骨孔换能器的术中超声检查在神经外科手术中已证明是有用的。
