We present our technique for deep brain stimulation (DBS) of the subthalamic nucleus (STN) and include information which may be helpful in general DBS. With the patient in a stereotactic head frame, the anterior and posterior commissures are identified on SPGR-sequence magnetic resonance imaging (MRI). STN coordinates are based on a stereotactic brain atlas at 12 mm lateral, 2 mm posterior and 5 mm caudal to the midcommissural point. Surgical navigation software allows for planning of the trajectory. Electromyography is used to quantitatively measure tremor responses to macrostimulation. Permanent lead placement is confirmed with intraoperative fluoroscopy and postoperative MRI.
我们介绍了我们用于丘脑底核（STN）深部脑刺激（DBS）的技术，并包含了可能对一般DBS有帮助的信息。患者处于立体定向头架中，在扰相梯度回波序列（SPGR）磁共振成像（MRI）上识别前连合和后连合。STN坐标基于立体定向脑图谱，位于连合中点外侧12mm、后方2mm和尾侧5mm处。手术导航软件可用于规划轨迹。肌电图用于定量测量对宏观刺激的震颤反应。术中透视和术后MRI确认永久性电极的放置。
