Поясничный стеноз позвоночного канала – патологическое сужение центрального позвоночного канала, латерального кармана или межпозвонкового отверстия. Частота осложнений хирургии данного дефекта составляет от 10 до 24 %. С целью снижения числа интраоперационных и ранних послеоперационных осложнений, сопровождающихся развитием неврологического дефицита, применяются различные методики интраоперационного нейрофизиологического мониторинга.</p><p>Цель исследования – изучение информативности интраоперационного нейрофизиологического мониторинга при хирургическом лечении дегенеративного поясничного стеноза позвоночного канала на базе нейрохирургического отделения ГБУ «Республиканская клиническая больница» (Йошкар‑Ола, Республика Марий Эл).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное исследование включены 69 декомпрессивно‑стабилизирующих оперативных вмешательств по поводу дегенеративного поясничного стеноза позвоночного канала на уровне L3–L5, выполненных с применением интраоперационного нейрофизиологического мониторинга (спонтанная электромиография, транскраниальные моторные вызванные потенциалы, соматосенсорные вызванные потенциалы, стимуляционная электромиография).</p></sec><sec><title>Результаты</title><p>Результаты. При проведении интраоперационного нейрофизиологического мониторинга у всех пациентов получены транскраниальные моторные вызванные потенциалы с нижних конечностей. В большинстве случаев зарегистрированы нормальные показатели соматосенсорных вызванных потенциалов, у 12 (17,4 %) пациентов исходные соматосенсорные вызванные потенциалы не получены вследствие сопутствующей соматической патологии. Методом стимуляционной электромиографии исследованы 308 установленных транспедикулярных винтов. Мышечные ответы получены в ходе 31 (45 %) операции, это 45 (14,6 %) винтов. Истинно отрицательные ответы получены при исследовании 29 (64,4 %) винтов, истинно положительные и ложноположительные – при стимуляции 12 (26,7 %) и 4 (8,9 %) винтов соответственно. В послеоперационном периоде у всех пациентов отсутствовал неврологический дефицит, неврологических признаков мальпозиции винтов не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение.

Lumbar spinal stenosis is a pathological constriction of the central spinal canal, lateral pocket or intervertebral foramen. The complication rate of lumbar spinal stenosis surgery ranges from 10 to 24 %. In order to reduce the number of intraoperative and early postoperative complications accompanied by the development of neurological deficit, various techniques of intraoperative neurophysiological monitoring are used.</p></sec><sec><title>Aim</title><p>Aim. Study of informativity of the use of intraoperative neurophysiological monitoring during surgical treatment of degenerative lumbar spinal stenosis based on the experience of the neurosurgical department of the Republican Clinical Hospital (Yoshkar‑Ola, Mari El Republic).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Thus, 69 decompressive‑stabilizing surgical interventions for degenerative lumbar spinal stenosis at the L3–L5 level, performed with intraoperative neurophysiological monitoring (free‑run electromyography, transcranial motor evoked potentials, somatosensory evoked potentials, triggered electromyography were included in the retrospective study).</p></sec><sec><title>Results</title><p>Results. During intraoperative neurophysiological monitoring transcranial motor evoked potentials from the legs was registered in all cases. Normal somatosensory evoked potentials were recorded in most cases, in 12 cases (17.4 %) baseline somatosensory evoked potentials were not registered due to preoperative neurological deficits and the presence of concomitant somatic pathology. 308 inserted pedicular screws were examined using the triggered electromyography. Muscle responses were registered in 31 (45 %) operations, 45 (14 %) screws. True negatives were registered with 29 (64.4 %), true positives were registered with 12 (26.7 %), and false positives were registered with 4 (8.9 %) screws. In the postoperative period no increase in motor and sensory neurological deficits was observed in all patients; no neurological signs of screw malpositioning were revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of multimodal intraoperative neurophysiological monitoring during surgical treatment of lumbar spinal stenosis reduces the risk of postoperative neurological complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>поясничный стеноз позвоночного канала</kwd><kwd>интраоперационный нейрофизиологический мониторинг</kwd><kwd>стимуляционная электромиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lumbar spinal stenosis</kwd><kwd>intraoperative neurophysiological monitoring</kwd><kwd>triggered electromyography</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">Issack P.S., Cunningham M.E., Pumberger M. et al.
