Abstract BACKGROUND Accurate electrode placement is critical to the success of deep brain stimulation (DBS) surgery. Suboptimal targeting may arise from poor initial target localization, frame-based targeting error, or intraoperative brain shift. These uncertainties can make DBS surgery challenging. OBJECTIVE To develop a computerized system to guide subthalamic nucleus (STN) DBS electrode localization and to estimate the trajectory of intraoperative microelectrode recording (MER) on magnetic resonance (MR) images algorithmically during DBS surgery. METHODS Our method is based upon the relationship between the high-frequency band (HFB; 500-2000 Hz) signal from MER and voxel intensity on MR images. The HFB profile along an MER trajectory recorded during surgery is compared to voxel intensity profiles along many potential trajectories in the region of the surgically planned trajectory. From these comparisons of HFB recordings and potential trajectories, an estimate of the MER trajectory is calculated. This calculated trajectory is then compared to actual trajectory, as estimated by postoperative high-resolution computed tomography. RESULTS We compared 20 planned, calculated, and actual trajectories in 13 patients who underwent STN DBS surgery. Targeting errors for our calculated trajectories (2.33 mm ± 0.2 mm) were significantly less than errors for surgically planned trajectories (2.83 mm ± 0.2 mm; P = .01), improving targeting prediction in 70% of individual cases (14/20). Moreover, in 4 of 4 initial MER trajectories that missed the STN, our method correctly indicated the required direction of targeting adjustment for the DBS lead to intersect the STN. CONCLUSION A computer-based algorithm simultaneously utilizing MER and MR information potentially eases electrode localization during STN DBS surgery.

Zusammenfassung. Wenn mit den ersten beiden anfallspräventiven Medikamenten keine Anfallsfreiheit erzielt werden konnte, so ist die Wahrscheinlichkeit, dies mit anderen Medikamenten zu erreichen, nur noch ca. 10 %. Es sollte dann geprüft werden, warum eine Pharmakoresistenz besteht und ob ein epilepsiechirurgischer Eingriff zur Anfallsfreiheit führen kann. Ist eine solche Operation nicht möglich, so können palliative Verfahren wie die Vagus-Nerv-Stimulation (VNS) und die tiefe Hirnstimulation (Deep Brain Stimulation) in eine bessere Anfallskontrolle ermöglichen. Insbesondere bei schweren kindlichen Epilepsien stellt auch die ketogene Diät eine zu erwägende Option dar.
