This modified hemispherectomy procedure effectively controlled seizures in children with unilateral brain disease. The technique reduced complications and improved motor and speech functions, offering a safer surgical option.

Area of Science:

  • Neurosurgery
  • Pediatric Neurology

Background:

  • Hemispherectomy is a treatment for severe unilateral hemispheric disease causing seizures.
  • Anatomical hemispherectomy has risks like hemosiderosis and hydrocephalus.
  • Modified techniques aim to improve safety and efficacy.

Observation:

  • A modified disconnective hemispherectomy was performed on 2 pediatric patients.
  • Stereotactic navigation was used in one case.
  • The procedure involved transventricular disconnection with minimal cortical resection.

Findings:

  • One patient achieved complete seizure control; the other had significant seizure reduction.
  • Both patients showed marked improvements in motor function and speech.
  • Procedures resulted in less blood loss and no reported postoperative complications compared to anatomical hemispherectomy.

  • Hospital stays were short, ranging from 7 to 14 days.

    • Implications:

    • This modified hemispherectomy offers a potentially safer and more effective surgical option for pediatric seizure disorders.
    • The technique may reduce the incidence of severe complications associated with traditional hemispherectomy.
    • Further research could validate this approach in larger pediatric populations.
