The purpose of this study was to analyze the feasibility and utility of 3D imaging to help lead positioning during a deep brain stimulation (DBS) procedure. A bilateral subthalamic DBS procedure was conducted in 2 patients for idiopathic Parkinson's disease. Subthalamic nucleus targeting was based on preoperative stereotactic MRI. We used the Medtronic O-arm to perform 2D-imaging control (frontal and lateral) as well as quick (<30 s) 3D acquisition. This allowed us to check the positioning of micro-macro electrodes and definite electrodes. 3D images were fused with postoperative CT to assess their accuracy, and with preoperative MRI to visualize the anatomical location of the electrodes. 3D imaging is a quick and safe method to ensure perioperative control of lead placement during DBS procedures.
本研究的目的是分析三维成像在深部脑刺激（DBS）手术中辅助电极定位的可行性和实用性。对2例特发性帕金森病患者进行了双侧丘脑底核DBS手术。丘脑底核靶点基于术前立体定向MRI。我们使用美敦力O型臂进行二维成像控制（前后位和侧位）以及快速（<30秒）三维采集。这使我们能够检查微宏电极和确定电极的位置。将三维图像与术后CT融合以评估其准确性，并与术前MRI融合以可视化电极的解剖位置。三维成像是一种快速且安全的方法，可确保在DBS手术期间对电极放置进行围手术期控制。
