Functional hemispherectomy in children
1Division of Neurosurgery, Montreal Neurological Hospital, McGill University, Quebec, Canada.
Insights
Functional hemispherectomy effectively controls intractable seizures in children, with 82% becoming seizure-free. This epilepsy surgery also improved cognitive function and sociability in patients.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Epilepsy Research
Background:
- Pharmacologically refractory epilepsy in children poses significant treatment challenges.
- Functional hemispherectomy is a surgical option for intractable seizures.
- Previous concerns existed regarding complications like superficial cerebral hemosiderosis.
Purpose of the Study:
- To evaluate the efficacy and safety of functional hemispherectomy in pediatric patients with intractable seizures.
- To assess seizure control, neurological outcomes, and complications associated with the procedure.
Main Methods:
- A retrospective review of 18 pediatric patients undergoing functional hemispherectomy.
- Patients had intractable seizures due to various neurological conditions.
- Outcomes assessed included seizure frequency, intellectual capacity, and sociability.
Main Results:
- 82% of patients achieved complete seizure freedom post-surgery.
- An additional 11.5% experienced at least an 80% reduction in seizure frequency.
- No cases of superficial cerebral hemosiderosis were observed, unlike in anatomical hemispherectomy.
Conclusions:
- Functional hemispherectomy is a highly effective treatment for pediatric intractable epilepsy.
- The procedure demonstrates a favorable safety profile with significant seizure reduction and improved patient quality of life.
- This surgical approach offers a viable solution for children with severe, drug-resistant epilepsy.
Abstract:
Functional hemispherectomy, indicated for the control of pharmacologically refractory seizures, has been used at the Montreal Neurological Hospital since 1974. We have used this technique in 18 children suffering from intractable seizures secondary to conditions such as infantile hemiplegia, chronic encephalitis, head trauma, cerebrovascular accident, brain dysplasia and Sturge-Weber angiomatosis. None has developed superficial cerebral hemosiderosis often seen following the classical anatomical hemispherectomy. Eighty-two per cent (82%) of patients have been seizure-free since hospital discharge while another 11.5% have had at least 80% reduction in their seizure frequency. Most patients have shown an improvement in their intellectual capacity and sociability.
