Robotic systems are gaining acceptance as a preferred tool for the placement of electrodes for stereotactic electroencephalography (SEEG) studies.
To describe the technical methods for insertion of SEEG using the Medtronic Stealth Autoguide robotic system and detailed outcomes in the initial 9 patients implanted.
Nine patients underwent placement of electrodes for SEEG studies with the use of the Autoguide system. Patients had at least 10 electrodes placed. Targets were planned on a Stealth S8 planning station, and electrodes were placed under general anesthesia. A technique for placement is described in detail. Patient outcomes and accuracy of electrode placement were evaluated. Methods to improve accuracy were investigated. Comparison of postoperative MRIs with preoperative planning MRIs was performed to determine the accuracy of electrode placement.
One hundred two electrodes were placed in 9 patients. Methods for placement and technical nuances are detailed. The distance from the planned target to the actual position of the electrode tip was measured in 8 of the 9 patients. The mean Euclidean distance was 4.67 ± 0.27 mm. There was 1 placement-related hemorrhage deficit in the first patient, and no deaths or infections. Adequate positioning of electrodes for seizure monitoring was obtained in all patients.
Autoguide can be used for placement of electrodes for SEEG studies with acceptable degrees of patient safety, accuracy, and efficiency. Considering the cost of Autoguide compared with other robotic devices, it may be attractive option.
机器人系统作为立体定向脑电图（SEEG）研究电极放置的首选工具越来越被接受。
描述使用美敦力 Stealth Autoguide 机器人系统插入 SEEG 的技术方法，并详细介绍最初植入的 9 名患者的结果。
9 名患者使用 Autoguide 系统进行 SEEG 研究电极的放置。患者至少放置 10 个电极。在 Stealth S8 规划站规划靶点，在全身麻醉下放置电极。详细描述了一种放置技术。评估了患者的结果和电极放置的准确性。研究了提高准确性的方法。对术后 MRI 与术前规划 MRI 进行比较，以确定电极放置的准确性。
9 名患者共放置 102 个电极。详细介绍了放置方法和技术要点。在 9 名患者中的 8 名患者中测量了从计划靶点到电极尖端实际位置的距离。平均欧几里得距离为 4.67 ± 0.27 毫米。第 1 例患者发生 1 例与放置相关的出血不足，无死亡或感染。所有患者均获得了用于癫痫监测的电极的适当定位。
Autoguide 可用于放置 SEEG 研究电极，具有可接受的患者安全性、准确性和效率。考虑到 Autoguide 与其他机器人设备的成本相比，它可能是一个有吸引力的选择。
