Cerebrovascular and endovascular neurosurgeon Risheng Xu discusses a new treatment for intractable pediatric epilepsy which can affect up to 30% of children with epilepsy. For poorly localized seizures, children have traditionally undergone hemispherectomy. Dr. Xu has worked with pediatric neurosurgeon Dody Robinson and the pediatric epilepsy team at Johns Hopkins to push forward endovascular hemispherectomy, a new minimally invasive procedure. In this approach, instead of surgically making disconnections, Xu goes into the hemisphere that needs to be treated and selectively embolizes and eliminates the blood flow to the areas of the brain that are seizing. Dr. Xu has seen good outcomes with four pediatric patients who have undergone this procedure, which was published as a case series in the Journal of NeuroInterventional Surgery. All four patients had a substantial reduction in seizure and three patients are seizure-free. #endovascular #johnshopkins #pediatricepilepsy #epilepsy https://www.hopkinsmedicine.org/neurology-neurosurgery/specialty-areas/epilepsy Journal of NeuroInterventional Surgery https://jnis.bmj.com/content/early/2025/05/29/jnis-2025-023265
