Arteriovenous Malformations-Associated Epilepsy in Pediatrics.

Area of Science:

• Pediatric Neurology
• Neurosurgery
• Epileptology

Background:

• Cerebral arteriovenous malformations (AVMs) are a significant cause of epilepsy in children.
• Pediatric AVM-associated epilepsy requires effective long-term management strategies.

Purpose of the Study:

• To evaluate the long-term epilepsy outcomes in pediatric patients treated for cerebral arteriovenous malformations (AVMs).
• To assess the impact of multimodality AVM treatment on seizure control and functional outcomes in children.

Main Methods:

• Retrospective chart review of pediatric patients with AVM-associated epilepsy (2005-2018).
• Analysis of demographic data, treatment modalities (surgical resection, embolization, conservative management), and epilepsy outcomes (seizure freedom, Engel Class).

Main Results:

• Of 18 pediatric patients with AVM-related epilepsy, 13 underwent surgical resection with 92.31% achieving complete AVM resection.
• Postoperatively, 61.54% achieved seizure freedom, and 92.31% were modified Engel Class I.
• 80% of patients treated without open surgery (conservative or embolization) also achieved seizure freedom.

Conclusions:

• Multimodality treatment of cerebral arteriovenous malformations in pediatric patients leads to favorable long-term epilepsy outcomes.
• Surgical AVM treatment offers significant seizure control, with high rates of seizure freedom and excellent functional outcomes.
• Further research is needed to fully characterize long-term outcomes for pediatric AVM-associated epilepsy.
