Vagus nerve stimulation in pediatric patients with intractable epilepsy: case series and operative technique.
Patients with epilepsy refractory to medical therapy or who experience intolerable side effects from the medication may benefit from placement and activation of a vagus nerve stimulator (VNS) (Cyberonics, Houston, TX). We present our experience with the VNS implanted by a pediatric surgeon and its activation managed by a pediatric neurologist. Six patients (one male and five females) with average age 11 years, 10 months (range 7 years, 4 months to 18 years, 1 month) received VNS implants at a community-based teaching hospital. One patient developed a self-inflicted wound complication secondary to persistent trauma at the implant site that led to removal of the implant. Before VNS implantation the frequency of seizures among the remaining five patients averaged 73 per patient per month (range 20-165). Length of follow-up averaged 6.5 months (range 1.5-11 months). At most recent follow-up seizure frequency averaged 14 per month (range 1-42); this represents an average reduction of 78 per cent (range 30-99%). We conclude that a pediatric surgeon with pediatric neurologic support can safely and effectively perform the VNS implantation at a hospital equipped to administer anesthesia to pediatric patients.
