Radiofrequency ablation of epileptogenic periventricular heterotopia

Background. Periventricular heterotopia is one of the causes intractable epilepsy. Different treatments this pathology show variable efficacy. Aim. To present result radiofrequency ablation periventricular in a patient with drug‑resistant Materials and methods. 33‑year‑old female has been suffering from epilepsy since age 19 frequent focal seizures (up to 70–80 times month) bilateral tonic‑clonic 4–6 year). In 2018 underwent resection right temporal lobe its medial structures partial located lateral ventricle. The frequency after 1 st surgical treatment increased till 150 per month, – up 3–4 month. After additional examination stereotaxic on side was performed 2019 Department Functional Neurosurgery Federal Neurosurgical Center (Novosibirsk). total 5 spots were made heterotopia. Follow‑up period 14 months. Right operation transient left‑sided hemiparesis developed 4 score MRC scale) which regressed by time discharge. During months follow‑up had 3 seizures, however, 2 nd did not appear. Conclusion. This clinical case demonstrates sufficient efficacy relative safety
