Aggravation of seizures and status epilepticus after vagal nerve stimulation therapy: the first pediatric case and review of the literature
We describe the first child with drug-resistant epilepsy in whom vagus nerve stimulation aggravated seizures and emerged status epilepticus after the increase in vagal nerve stimulation current output.
A 13-year-old girl presented with refractory secondary generalized focal epilepsy. Vagal nerve stimulator was implanted because of drug-resistant epilepsy. After the increase of vagal nerve stimulator current output to a relatively high level, the patient experienced seizure aggravation and status epilepticus.
We conclude that vagus nerve stimulation may induce paradoxical seizures and may lead to status epilepticus, similarly to some antiepileptic drugs.
