Summary

Microelectrode implantation during deep brain stimulation (DBS) surgery can have significant deviations from the intended target. Intraoperative CT scans can help assess these deviations, improving the interpretation of microelectrode recordings (MER).

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neuromodulation

Background:

  • Intraoperative microelectrode recording using the Ben Gun microdrive system is crucial for Deep Brain Stimulation (DBS) surgery.
  • Accurate microelectrode localization is essential for effective DBS and interpretation of microelectrode recordings (MER).

Purpose of the Study:

  • To investigate the imprecision of microelectrode implantation using the Ben Gun microdrive system during DBS surgery.
  • To quantify the deviation of microelectrodes from their theoretical positions.

Main Methods:

  • Analysis of the stereotactic position of 135 microelectrodes in 16 Parkinson's disease patients undergoing DBS surgery.
  • Utilizing intracranial CT (iCT) integrated with a stereotactic planning system to determine microelectrode coordinates.
  • Comparing simultaneous microelectrode positions to assess 3D Euclidean deviation, 2D probe's eye view deviation, and deviation from the theoretical inter-electrode distance.

Main Results:

  • Median deviation was 0.64 mm in 3D and 0.58 mm in 2D.
  • A significant percentage of satellite electrodes deviated substantially from the theoretical 2 mm distance from the central electrode.
  • Imprecision was similar across axes (X, Y) but less in the Z-axis; bilateral implantations did not increase deviation risk.

Conclusions:

  • A notable percentage of microelectrodes deviate significantly from their intended targets in DBS procedures.
  • Intraoperative CT imaging can be used to estimate microelectrode deviation and enhance MER interpretation during surgery.
