Summary
This study details a deep brain stimulation (DBS) technique for the subthalamic nucleus (STN). It outlines precise targeting and confirmation methods for effective surgical outcomes in patients.
Area of Science:
- Neurosurgery
- Neurology
- Medical Imaging
Background:
- Deep brain stimulation (DBS) is a therapeutic option for neurological disorders.
- Accurate targeting of the subthalamic nucleus (STN) is crucial for effective DBS.
Purpose of the Study:
- To present a detailed technique for subthalamic nucleus (STN) deep brain stimulation (DBS).
- To provide guidance for general DBS procedures.
Main Methods:
- Patient preparation using a stereotactic head frame.
- Identification of anatomical landmarks using SPGR-sequence MRI.
- STN targeting based on stereotactic atlas coordinates relative to the midcommissural point.
- Surgical navigation software for trajectory planning.
- Intraoperative electromyography (EMG) for tremor response assessment.
- Confirmation of lead placement via intraoperative fluoroscopy and postoperative MRI.
Main Results:
- The described method allows for precise localization and placement of DBS leads in the STN.
- Electromyography effectively quantifies tremor responses to stimulation.
- Imaging modalities confirm accurate lead positioning.
Conclusions:
- The presented technique offers a reliable approach for STN DBS.
- Integration of stereotactic imaging, navigation software, and electrophysiological monitoring ensures procedural accuracy and efficacy.
