Disconnective Hemispherotomy for Medically Intractable Status Epilepticus in an 8-Year-Old Child
Insights
A child with drug-resistant focal epilepsy caused by perinatal infarction experienced immediate seizure relief after a hemispherotomy surgery. This case highlights the effectiveness of surgical interventions for severe hemispheric epilepsies.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Epileptology
Background:
- Focal epilepsy in children can arise from perinatal insults like infarction.
- Refractory nonconvulsive status epilepticus presents a significant management challenge.
Observation:
- An 8-year-old child with left hemispheric epilepsy secondary to perinatal infarction developed new absence seizures and status epilepticus.
- The patient's condition was refractory to all medical treatments.
Findings:
- A disconnective surgical hemispherotomy was performed after multidisciplinary review.
- The surgery resulted in immediate and sustained seizure cessation, with the patient remaining seizure-free at 4 months post-operation.
Implications:
- Hemispherectomy and related disconnective procedures are effective for intractable hemispheric epilepsies.
- Surgical intervention offers a viable treatment option for pediatric patients with severe, medically refractory epilepsy.
Abstract:
We report here the unusual case of an 8-year-old child with left hemispheric focal epilepsy secondary to a perinatal infarction who presented with new onset absence seizures and eventual nonconvulsive status epilepticus that was refractory to medical management. Following review at our multidisciplinary Epilepsy Surgery conference, the patient underwent disconnective surgical hemispherotomy with immediate cessation of his seizures; and has remained seizure-free at 4 months following surgery. In this context, we present here an overview of hemispherectomy and related procedures, including peri-insular disconnective hemispherotomy, and we discuss the efficacy of surgery for challenging hemispheric epilepsies.
