Summary
Targeting the subthalamic nucleus (STN) is challenging due to its small size. This study details a refined technique for STN targeting in patients, improving surgical precision for movement disorder treatments.
Area of Science:
- Neurosurgery
- Neurology
- Stereotactic Surgery
Background:
- The subthalamic nucleus (STN) is a critical deep brain stimulation target for movement disorders.
- Its small size and proximity to critical structures present significant stereotactic targeting challenges.
Purpose of the Study:
- To present a detailed technique for accurate subthalamic nucleus (STN) targeting.
- To share combined surgical experience and refine patient selection criteria for STN interventions.
Main Methods:
- Utilized MRI, frame-based CT, and volumetric image fusion for precise targeting.
- Incorporated intraoperative techniques including neurologist presence, local field potential recording, impedance monitoring, and macrostimulation.
- Detailed post-operative imaging (CT/MRI) and test stimulation protocols.
Main Results:
- Experience encompasses 18 lesions and 27 stimulator implants in the STN across two centers.
- The presented technique aims to enhance the accuracy and safety of STN targeting.
Conclusions:
- Accurate STN targeting is achievable through meticulous technique and multimodal imaging.
- The described methodology, including specialized intraoperative monitoring, facilitates successful STN interventions for movement disorders.
