In case of ineffective conservative antiepileptic therapy, surgical treatment aimed at removing the epileptogenic focus may be applied. Resection procedures allow to eliminate seizures in most patients, but in 20–30% cases they persist or recur, thereby proposing to use some neuromodulation.</p></sec><sec><title>Objective</title><p>Objective: to assess effectiveness of neuromodulation in patients with drug-resistant epilepsy (DRE) after failed resection surgical interventions.</p></sec><sec><title>Material and methods</title><p>Material and methods. A retrospective data analysis was carried out involving 23 DRE patients who had undergone vagus nerve stimulation (VNS) or deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) or hippocampus (HP) after failed surgeries. The VNS system was implanted in 18 (78.3%) patients, the HP-DBS system – in 3 (13.0%), and the ANT-DBS system – in 2 (8.7%). The results after surgical interventions were assessed according to the Engel scale, VNS therapy – by the McHugh (MH) scale, DBS therapy – by the degree of reduced seizure rate as a percentage. The average follow-up was 56.5 months.</p></sec><sec><title>Results</title><p>Results. Patients with implanted VNS system were found to have the outcome presented as MH Ia–IIb in 3 (16.7%) cases, MH IIIa–IIIb in 10 (55.5%) cases, MH IV–V in 5 (27.8%) cases. In HP-DBS group, 2 out of 3 patients showed a decline in seizure rate by more than 50% from the baseline level, and 1 patient experienced an improvement in seizure severity. In the ANT-DBS group, one patient had a 60% reduction in seizure rate and an improvement in seizure severity, another one showed no change in seizure rate.</p></sec><sec><title>Conclusion</title><p>Conclusion. Neuromodulation in DRE patients can significantly lower seizure rate in more than half of patients after failed surgical treatment.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Актуальность</title><p>Актуальность. В ситуациях, когда консервативная противоэпилептическая терапия неэффективна, возможно хирургическое лечение, направленное на удаление эпилептогенного очага. Резекционные операции позволяют избавиться от приступов в большинстве случаев, однако у 20–30% больных они сохраняются или рецидивируют. В таких случаях пациентам может быть предложен тот или иной вид нейромодуляции.</p></sec><sec><title>Цель</title><p>Цель: оценка эффективности проведения нейромодуляции у пациентов с фармакорезистентной эпилепсией (ФРЭ) после неудачных резекционных хирургических вмешательств.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведен ретроспективный анализ данных 23 пациентов, которым после неудачной операции по поводу ФРЭ проводилась стимуляция блуждающего нерва (англ. vagus nerve stimulation, VNS) либо глубокая стимуляция (англ. deep brain stimulation, DBS) переднего ядра таламуса (англ. anterior nucleus of the thalamus, ANT) или гиппокампа (англ. hippocampus, HP). Система VNS имплантирована 18 (78,3%) больным, система HP-DBS – 3 (13,0%), система ANT-DBS – 2 (8,7%). Результаты хирургических вмешательств оценивали по шкале Engel, VNS-терапии – по шкале McHugh (MH), DBS-терапии – по степени снижения частоты приступов в процентах. Средний катамнез наблюдения составил 56,5 мес.</p></sec><sec><title>Результаты</title><p>Результаты. В группе пациентов, которым была имплантирована система VNS, у 3 (16,7%) исход составил MH Ia–IIb, у 10 (55,5%) – MH IIIa–IIIb, у 5 (27,8%) – MH IV–V. В группе HP-DBS у 2 больных из 3 отмечено снижение частоты приступов более чем на 50% от исходного уровня, у 1 пациента наблюдалось облегчение тяжести приступов. В группе ANT-DBS у одного больного зарегистрировано снижение частоты приступов на 60% и облегчение тяжести приступов, у второго изменений в частоте приступов не отмечено.</p></sec><sec><title>Заключение</title><p>Заключение. Нейромодуляция у пациентов с ФРЭ позволяет значимо уменьшить частоту приступов у более чем половины пациентов после неудачного оперативного лечения.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Фармакорезистентная эпилепсия</kwd><kwd>противоэпилептическая терапия</kwd><kwd>хирургическая резекция</kwd><kwd>нейромодуляция</kwd><kwd>стимуляция блуждающего нерва</kwd><kwd>VNS</kwd><kwd>глубокая стимуляция мозга</kwd><kwd>DBS</kwd><kwd>переднее ядро таламуса</kwd><kwd>гиппокамп</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Drug-resistant epilepsy</kwd><kwd>antiepileptic therapy</kwd><kwd>surgical resection</kwd><kwd>neuromodulation</kwd><kwd>vagus nerve stimulation</kwd><kwd>VNS</kwd><kwd>deep brain stimulation</kwd><kwd>DBS</kwd><kwd>anterior nucleus of the thalamus</kwd><kwd>hippocampus</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Salanova V., Sperling M.R., Gross R.E., et al.
