Summary
A new Standardized Electrode Nomenclature for SEEG Applications system offers clear, unique labels for stereoelectroencephalography (SEEG) electrodes. This system improves communication and collaboration in epilepsy research and clinical practice.
Area of Science:
- Neurology
- Neurosurgery
- Medical Device Technology
Background:
- Stereoelectroencephalography (SEEG) is a crucial invasive method for seizure localization in medically refractory epilepsy.
- Current SEEG electrode naming lacks standardization, leading to confusion and hindering collaboration among clinical and research teams.
Purpose of the Study:
- To introduce a novel, standardized nomenclature for SEEG electrodes.
- To enhance clarity, uniqueness, and informativeness in electrode labeling for SEEG procedures.
Main Methods:
- Development of the Standardized Electrode Nomenclature for SEEG Applications (SENA) system.
- Evaluation of inter-rater agreement using 10 cases (136 electrodes) with blinded raters.
- Prospective implementation in 40 consecutive patients undergoing SEEG monitoring.
Main Results:
- The SENA system successfully generated unique electrode names for all implanted electrodes.
- Implementation facilitated implantation design, SEEG recording interpretation, and treatment planning.
- Achieved a high inter-rater agreement of 97.5% among neurosurgeons and neurologists.
Conclusions:
- The SENA system provides a simple, reproducible, and informative method for SEEG electrode identification.
- This standardization enhances information sharing in clinical and research settings.
- Widespread adoption of SENA can improve communication and collaboration in epilepsy management.
