Интраоперационный мониторинг (ИОМ) зрительных вызванных потенциалов (ЗВП) используют для информирования хирургов о воздействиях на зрительную систему с целью предотвращения ятрогенных нарушений зрения. ИОМ ЗВП начали широко применять лишь в последнее десятилетие. В настоящий момент отсутствует общепринятая методика его проведения, а эффективность ИОМ ЗВП и определяющие ее факторы изучены недостаточно.Цель исследования – проанализировать факторы, влияющие на возможность проведения и эффективность ИОМ ЗВП.Материалы и методы. Ретроспективно рассмотрены данные по 240 последовательным нейрохирургическим операциям, выполнявшимся с применением ИОМ ЗВП. Анализировали данные ИОМ (параметры регистрации, наличие и тип изменений ЗВП), характеристики пациентов (пол, возраст, тип и локализация объемных образований, наличие дооперационных нарушений зрения), параметры анестезии и послеоперационные изменения зрения. Статистический анализ выполняли с помощью тестов χ2 и Манна–Уитни.Результаты. ЗВП удавалось получить для 91,3 % глаз с полностью или частично сохраненным зрением. Основными факторами, уменьшающими вероятность успешного проведения ЗВП, были дооперационные нарушения зрения и применение ингаляционной анестезии. Персонализированный подход к выбору референтных электродов и параметров частотной фильтрации позволил сократить число усреднений при записи ЗВП и ускорить информирование хирургов. При успешном мониторинге клинически значимые изменения ЗВП отсутствовали для 59,1 % глаз, признаки интраоперационного улучшения зрения зафиксированы для 5,8 %, признаки ухудшения – для 35,1 %. Из последних в 60,7 % случаев ЗВП впоследствии восстановились полностью. После операции новые нарушения зрения выявлены в 2,6 % глаз без признаков интраоперационных нарушений, 6,7 % – с признаками временных нарушений и 19,3 % – с признаками нарушений, сохранявшимися до окончания мониторинга. Оценку чувствительности и специфичности ИОМ ЗВП ограничивают возможность возникновения осложнений в раннем послеоперационном периоде и влияние данных мониторинга на ход и результаты операции. Доля тотальных резекций была максимальной, если мониторинг ЗВП удавался; в подгруппе без дооперационных нарушений зрения наличие тревоги при мониторинге было связано со снижением доли тотальных резекций за счет роста доли субтотальных.Заключение. Интраоперационный мониторинг ЗВП с использованием персонализированного подхода позволяет эффективно контролировать сохранность зрительной функции при нейрохирургических операциях.</p></abstract><trans-abstract xml:lang="en"><p>Background. Intraoperative monitoring (IOM) of visual evoked potentials (VEPs) is used to inform surgeons about impacts on the visual system in order to prevent iatrogenic visual impairment. The VEP monitoring use become widespread only in the last decade; nowadays, there is no generally accepted methodology for its implementation, and the effectiveness of VEP monitoring and the factors determining it have not been sufficiently studied.Aim. The aim of the study was to investigate the factors influencing the VEP monitoring feasibility and effectiveness.Materials and methods. Data from 240 consecutive neurosurgical operations performed using VEP monitoring were retrospectively reviewed. IOM data (registration parameters, presence and type of VEP changes), patient characteristics (gender and age, tumor type and location, presence of preoperative visual dysfunctions), anesthesia parameters and postoperative changes in vision were studied. Statistical analysis was performed using χ2 and Mann–Whitney tests.Results. VEPs were obtained in 91.3 % of eyes with completely or partially preserved vision. The main factors reducing the chances to record VEPs successfully are preoperative visual disorders and the use of inhalation anesthesia. A personalized approach to the selection of reference electrodes and frequency filtering parameters makes it possible to reduce the number of averagings required for VEP recording and accelerate informing surgeons. With successful monitoring 59.1 % of eyes had no noticeable VEP changes; 5.8 % of eyes had signs of intraoperative improvement; 35.1 % had signs of deterioration. Among the last category, 60.7 % of eyes had full VEPs recovery afterwards. After surgery, new visual disorders were detected in 2.6 % of eyes without signs of intraoperative deterioration, in 6.7 % – with temporary deterioration, and in 19.3 % – with signs of deterioration persisted until IOM is finished. Assessing the sensitivity and specificity of VEP monitoring is hampered by the possibility of complications in the early postoperative period and IOM influence on the course and results of the operation. The proportion of total resections was maximal when VEP monitoring was successful. In the subgroup without preoperative visual impairments, the alarms during monitoring were associated with decrease in proportion of total resections proportion due to increase in proportion of subtotal resections.Conclusion. VEP monitoring with a personalized approach allows effective monitoring of visual functions preservation during neurosurgical operations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интраоперационный нейрофизиологический мониторинг</kwd><kwd>зрительные вызванные потенциалы</kwd><kwd>персонализированная методика</kwd><kwd>ятрогенное нарушение</kwd><kwd>радикальность операций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intraoperative neurophysiological monitoring</kwd><kwd>visual evoked potentials</kwd><kwd>personalized approach</kwd><kwd>iatrogenic disorder</kwd><kwd>surgical radicality</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при финансовой поддержке Российского научного фонда, грант № 23-25-00322.</funding-statement><funding-statement xml:lang="en">The research was funded by Russian Science Foundation, Grant Number 23-25-00322.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cedzich C., Schramm J., Mengedoht C.F., Fahlbusch R.
