Stereotactic removal of intracerebral hematoma is a routine procedure for treating hypertensive intracerebral hemorrhage, but the complex sequence of operations limits its adoption. We explored the application of a novel surgical technique for the removal of spontaneous intracerebral hematomas. The surgical technique based on computed tomography (CT) images was used in hematoma projection and surgical planning. Markers placed on the scalp based on an Android smartphone app allowed the installation of a stereotactic head frame to facilitate the selection of the best trajectory to the hematoma center for removing the hematoma. Forty-two patients with spontaneous intracerebral hemorrhage were included in the study, including 33 cases of supratentorial hemorrhage, 5 cases of cerebellum hemorrhage, and 4 cases of brain stem hemorrhage. The surgical technique combined with the stereotactic head frame helped the tip of the drainage tube achieve the desired position. The median surgical time was 45 (range 25-75) min. The actual head frame operating time was 10 (range 5-15) min. Target alignment performed by the surgical technique was accurate to ≤ 10.0 mm in all 42 cases. No patient experienced postoperative rebleeding. In 33 cases of supratentorial intracerebral hemorrhage, an average evacuation rate of 77.5% was achieved at postoperative 3.1 ± 1.4 days, and 29 (87.9%) cases had a residual hematoma of < 15 ml. The novel surgical technique helped to quickly and effortlessly localize hematomas and achieve satisfactory hematoma removal. Clinical application of the stereotactic head frame was feasible for intracerebral hemorrhage in various locations.

自发性脑内血肿清除的新型外科技术。

立体定向清除脑内血肿是治疗高血压性脑出血的常规方法，但是手术的复杂程序限制了其的采用。我们探索了一种新型手术技术在自发性脑血肿清除中的应用。基于计算机断层扫描（CT）图像的手术技术被用于血肿投影和手术计划。基于Android智能手机应用程序放置在头皮上的标记允许安装立体定向头架，以方便选择通往血肿中心的最佳轨迹以去除血肿。本研究纳入了42例自发性脑出血患者，其中包括33例幕上出血，5例小脑出血和4例脑干出血。手术技术与立体定位头架相结合，帮助引流管的尖端达到所需位置。中位手术时间为45分钟（范围为25-75）。实际的头架操作时间为10分钟（范围5-15）。通过手术技术进行的目标对准在所有42例中均精确到≤10.0 mm。没有患者经历术后再出血。在33例幕上脑出血中，术后3.1±1.4天平均撤离率为77.5％，其中29例（87.9％）残余血肿<15 ml。新颖的手术技术有助于快速，轻松地定位血肿并实现令人满意的血肿清除。立体定向头架的临床应用对于不同部位的脑出血是可行的。
