Summary
Excisional surgery for drug-resistant epilepsy in infants is safe and effective. Surgical intervention in infants with medically uncontrolled malignant partial seizures can lead to seizure freedom or significant reduction, improving long-term outcomes.
Area of Science:
- Pediatric Neurosurgery
- Pediatric Neurology
- Epilepsy Surgery
Background:
- Limited data exists on excisional surgery for drug-resistant epilepsy in infants.
- Malignant partial seizures in infants can lead to developmental deterioration.
- Standard antiepileptic drug (AED) therapies are often ineffective and toxic in this population.
Observation:
- Five infants under one year of age with medically refractory epilepsy underwent surgical evaluation.
- Patients experienced frequent daily seizures despite maximal AED therapy at therapeutic levels.
- Significant medication toxicity was observed in all participants.
Findings:
- Complete resection of epileptic foci in three infants resulted in complete seizure freedom.
- Partial resection in two infants led to a significant reduction in seizure frequency.
- No significant neurological deficits or developmental compromise were observed post-surgery.
Implications:
- Excisional surgery is a safe and viable option for selected infants with medically uncontrolled malignant partial seizures.
- Early surgical intervention may significantly improve long-term seizure control and developmental trajectories.
- Referral to specialized pediatric epilepsy centers is recommended for surgical evaluation in these complex cases.
