Radiosurgical corpus callosotomy significantly reduced seizure severity and frequency in three patients with intractable epilepsy. This gamma knife procedure offers a promising alternative to open surgery with minimal complications.

Area of Science:

  • Neurosurgery
  • Epilepsy Treatment
  • Radiosurgery

Background:

  • Corpus callosotomy is an option for medically uncontrolled generalized epilepsy.
  • Open callosotomy is associated with reported complications.
  • Gamma knife radiosurgery offers a less invasive approach.

Observation:

  • Three patients with intractable epilepsy underwent stereotactic radiosurgery targeting the anterior corpus callosum.
  • Patients had a history of seizures ranging from 20 to 37 years.
  • The procedure involved precise gamma knife targeting of the corpus callosum.

Findings:

  • Significant reduction in seizure severity and frequency observed in all patients.
  • Atonic and generalized tonic-clonic seizures showed the most improvement.

  • Mean follow-up was 38 months with a 3-day hospitalization and no major complications.

    • Implications:

    • Radiosurgical corpus callosotomy presents a promising alternative to open surgical interventions.
    • This technique may offer a safer treatment option for refractory epilepsy.
    • Further research is warranted to explore the long-term efficacy and broader application of this radiosurgical approach.
