Epilepsy surgery in infants can effectively control severe seizures, with many achieving seizure freedom or significant improvement. This intervention offers hope for developmental progress in carefully selected young patients.

Area of Science:

  • Pediatric Neurosurgery
  • Epileptology
  • Developmental Neurology

Background:

  • Infantile epilepsy, particularly catastrophic forms, presents significant challenges.
  • Early diagnosis and intervention are crucial for optimal outcomes in affected infants.

Purpose of the Study:

  • To evaluate the efficacy and safety of epilepsy surgery in infants with catastrophic epilepsy.
  • To assess surgical outcomes in relation to underlying etiologies and seizure characteristics.

Main Methods:

  • Surgical resection or functional hemispherectomy was performed on 12 infants (age 2.5-29 months).
  • Preoperative evaluation included MRI, PET, and EEG to localize epileptogenic lesions.
  • Histopathologic examination confirmed diagnoses such as focal cortical dysplasia, Sturge-Weber syndrome, ganglioglioma, and hemimegalencephaly.

Main Results:

  • At a mean follow-up of 32 months, 6 patients were seizure-free (Engel class I), 3 had rare seizures (Engel class II), and 2 showed worthwhile improvement (Engel class III).
  • Most patients experienced developmental catch-up post-surgery, except for one with hemimegalencephaly.
  • Complications were rare and manageable; no new neurological deficits occurred, and one patient's hemiparesis resolved.

Conclusions:

  • Epilepsy surgery is a viable treatment option for catastrophic epilepsy in carefully selected infants.
  • Surgical intervention can lead to seizure control and improved developmental trajectories.
