Multiple subpial transections (MSTs) offer significant seizure reduction for intractable epilepsy, even without resection. This epilepsy surgery shows efficacy with minimal neurological compromise, suggesting MST as a viable standalone procedure.

Area of Science:

  • Neurosurgery
  • Epileptology
  • Clinical Neurology

Background:

  • Medically intractable epilepsy poses significant challenges for patient management.
  • Limited patient numbers at single centers hinder robust clinical and statistical analysis for rare procedures.
  • Multiple subpial transections (MSTs) are an option for specific epilepsy cases.

Purpose of the Study:

  • To evaluate the indications and outcomes of multiple subpial transections (MSTs).
  • To assess the efficacy and safety of MSTs in patients with medically intractable epilepsy.
  • To compare outcomes of MSTs with and without resection.

Main Methods:

  • A meta-analysis of data from six epilepsy centers was conducted.
  • Data included 211 patients undergoing MSTs for intractable epilepsy.

  • Preoperative evaluations, surgical procedures, seizure outcomes, and postoperative deficits were analyzed.

    • Main Results:

    • Excellent seizure reduction (>95%) was achieved in 68-87% of patients undergoing MST with resection.
    • MST without resection also demonstrated high efficacy (62-71% excellent outcome).
    • Neurologic deficits were comparable between MST with (23%) and without (19%) resection.

    Conclusions:

    • Multiple subpial transections (MSTs) show efficacy as a standalone procedure for intractable epilepsy.
    • MSTs offer a treatment option with minimal neurological compromise when resective surgery is not feasible.
    • Further research is warranted to refine criteria and predictive factors for MST outcomes.
