Изучение применимости метода ZLR для интраоперационной идентификации причинного сосуда, а также оценки полноты декомпрессии корешка тройничного нерва при классической невралгии тройничного нерва.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено проспективное исследование с участием 10 пациентов с кНТН. Вовремя МВД использовался протокол мониторинга ZLR, включающий стимуляцию сосудов в зоне нейроваскулярного конфликта биполярным концентрическим электродом в диапазоне 0,1–2,5мА, а также регистрацию мышечных ответов жевательной мышцы (ZLR, ZL-response) до и после МВД.</p><p>После операции проводилась клиническая оценка регресса болевого синдрома.</p></sec><sec><title>Результаты</title><p>Результаты. В 90 % случаев причинным сосудом была верхняя мозжечковая артерия. Порог стимуляции артерий до МВД составил 0,4 ± 0,22мА, после МВД – 1,5 ± 0,49мА (p &lt; 0,05). После декомпрессии в 54,5 % случаев ответ при стимуляции артерий до 2,5мА отсутствовал. Стимуляция вен требовала более высоких параметров (1,3 ± 0,61мА до МВД), а в большинстве случаев ответы с мышцы-мишени отсутствовали как до, так и после декомпрессии. После операции в 90 % случаев болевой синдром полностью регрессировал, однако в одном случае отмечалось частичное сохранение лицевой боли, которая на фоне проведения консервативной терапии полностью регрессировала.</p></sec><sec><title>Заключение</title><p>Заключение. Учитывая полученные параметры порогов стимуляции, метод ZL-ответа позволяет интраоперационно верифицировать причинный артериальный сосуд, а также оценить эффективность МВД, что подтверждается благоприятными клиническими исходами. Роль венозной компрессии требует дальнейшего изучения. Необходимы дальнейшие исследования для оценки прогностической значимости метода, а также роли венозной компрессии.</p></sec></abstract><trans-abstract xml:lang="en"><p>The availability of an objective, instrumental intraoperative method for assessing the eff ectiveness of microvascular decompression (MVD) in classical trigeminal neuralgia (cTN) is undoubtedly indispensable in modern neurosurgery.</p><sec><title>The aim</title><p>The aim. To study the applicability of the ZLR method for intraoperative identification of the causative vessel and assessment of the completeness of trigeminal nerve root decompression in classical trigeminal neuralgia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A prospective study was conducted involving 10 patients with cTN. During MVD, a ZLR monitoring protocol was used, including stimulation of vessels in the neurovascular confl ict zone with a bipolar concentric electrode in the range of 0.1–2.5 mA, as well as recording of the masseter muscle responses (ZLR, ZL-response) before and after MVD. Postoperative pain regression was clinically assessed.</p></sec><sec><title>Results</title><p>Results. In 90 % of cases, the causative vessel was the superior cerebellar artery (SCA). The arterial stimulation threshold before MVD was 0.4 ± 0.22 mA, after MVD – 1.5 ± 0.49 mA (p &lt; 0.05). After decompression, there was no response to arterial stimulation up to 2.5 mA in 54.5 % of cases. Venous stimulation required higher parameters (1.3 ± 0.61 mA before MVD), and in most cases, there was no response from the target muscle either before or after decompression. Postoperatively, pain completely regressed in 90 % of cases; however, in one case, partial persistence of facial pain was noted, which completely regressed with conservative therapy.</p></sec><sec><title>Conclusion</title><p>Conclusion. Given the obtained stimulation threshold parameters, the ZL response method allows for intraoperative verifi cation of the causative arterial vessel and assessment of the effectiveness of microvascular decompression, as evidenced by favorable clinical outcomes. The role of venous compression requires further study. Further research is needed to evaluate the prognostic signifi cance of this method, as well as the role of venous compression.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мониторинг ZLR</kwd><kwd>невралгия тройничного нерва</kwd><kwd>нейроваскулярный конфликт</kwd><kwd>микроваскулярная декомпрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ZLR monitoring</kwd><kwd>trigeminal neuralgia</kwd><kwd>neurovascular conflict</kwd><kwd>microvascular decompression</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">Di Carlo DT, Benedetto N, Perrini P.
