Integration of intraoperative ultrasound and depth-electrode electrocorticography for resection guidance in epilepsy surgery: technical workflow and feasibility
To demonstrate the feasibility, reproducibility, and potential clinical value of combining intraoperative depth-electrode electrocorticography (iECoG) and intraoperative ultrasound (ioUS) for resective epilepsy surgery, emphasizing its significance in improving surgical outcomes.
Key Findings:
The combined use of ioUS and depth-electrode iECoG enhances the localization and resection of the epileptogenic zone, with depth electrodes providing more informative functional assessment compared to conventional subdural strip iECoG, and real-time anatomical visualization from ioUS improving the delineation of lesion boundaries, supported by quantifiable data.
Interpretation:
Integrating ioUS with depth-electrode iECoG offers a promising approach to improve surgical outcomes in patients with drug-resistant epilepsy by refining the anatomical definition of resection limits.
Limitations:
Evidence is limited to isolated reports or single technical notes, and the study is retrospective, which may introduce selection bias that could affect the generalizability of the findings.
Conclusion:
The combination of ioUS and depth-electrode iECoG represents a novel intraoperative guidance strategy that could significantly enhance surgical precision and improve clinical outcomes in epilepsy surgery.
