Хирургическое лечение петрокливальных менингиом (ПКМ), особенно при их гигантских размерах, остается одной из самых сложных проблем в современной нейрохирургии и ассоциировано с высокими рисками послеоперационных осложнений и летальностью.</p><p>Цель исследования – определить характер и частоту развития послеоперационного дефицита при хирургии гигантских ПКМ, выявить прогностические факторы, влияющие на неврологические исходы и степень радикальности удаления данных опухолей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Ретроспективно изучены результаты хирургического лечения 18 пациентов, которым были выполнены 22 операции по удалению гигантских ПКМ. Оценивали неврологический и общесоматический статус пациентов перед операцией, сразу после нее и через 6 мес, а также нейровизуализационные характеристики опухолей до и после лечения. Анализировали влияние различных факторов на неврологические исходы и степень радикальности удаления опухолей.</p></sec><sec><title>Результаты</title><p>Результаты. Средний объем ПКМ до операции составил 46,3 ± 25,4 см3, средний объем резекции – 81 ± 16,8 % от исходного. Частота возникновения неврологического дефицита в раннем послеоперационном периоде составила 63,6 %, летальность – 0 %. Наиболее частым осложнением было повреждение черепно-мозговых нервов (63,6 %). Статус пациентов по шкале Карновского до операции (медиана 80 %) улучшился через 6 мес после операции (медиана 90 %). Интегративная оценка по шкале PCMIS (Petroclival Meningioma Impairment Scale) через 6 мес в среднем была равна предоперационному уровню (8,1 ± 6,3 и 7,5 ± 5,3 соответственно). Низкий статус по шкале Карновского до операции (&lt;70 %) не влиял на возникновение послеоперационного дефицита (p = 0,465).</p></sec><sec><title>Заключение</title><p>Заключение. Гигантские ПКМ – сложная проблема современной нейрохирургии. Пациентам с такими опухолями при субкомпенсированном состоянии нередко отказывают в проведении хирургической операции. Однако представленные результаты показывают, что данный вид операций при использовании описанных нами принципов хирургического лечения позволяет в большинстве случаев достичь улучшения состояния больных через 6 мес после операции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Surgical treatment of petroclival meningiomas (PCM), especially of giant PCM, remains one of the most difficult problems in neurosurgery and is associated with high risks of postoperative morbidity and mortality.</p></sec><sec><title>Aim</title><p>Aim. to determinate frequency and reversibility of post-operative neurological deficit after giant PCMs resection as well as identify risk factors of this surgery and the resection quality of these tumors.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The results of surgical treatment of 18 patients underwent 22 operations to resect giant PCMs were retrospectively studied. The neurological status and Karnofsky Performance Scale (KPS) of patients were assessed before surgery, immediately after and 6 months later, as well as neuroimaging characteristics of tumors before and after surgery were studied. We analyzed the influence of various factors on neurological outcomes and the resection quality.</p></sec><sec><title>Results</title><p>Results. The average PCM volume before surgery was 46.3 ± 25.4 cm3, the average resection volume was 81 ± 16.8 %. The incidence of neurological deficit in the early postoperative period was 63.6 %, mortality was 0 %. The most common complication was injury of cranial nerves (63.6 %). The scores according to Karnofsky Performance Scale (KPS) before surgery (median 80 %) improved 6 months after surgery (median 90 %). The PCMIS after 6 months was on average equal to the preoperative level (8.1 ± 6.3 and 7.5 ± 5.3, respectively). Low Karnofsky Performance Scale status before surgery (&lt;70 %) did not affect the occurrence of postoperative deficit (p = 0.465)</p></sec><sec><title>Conclusion</title><p>Conclusion. Surgery of giant PCMs is a difficult problem. Subcompensated patients with these tumors are often rejected in surgical treatment, however, our results demonstrate that this surgery leads in most cases to an improvement in the patients’ neurological condition in 6 months after surgery, while using the surgical treatment principles described by us.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>петрокливальная менингиома</kwd><kwd>сфенопетрокливальная менингиома</kwd><kwd>компрессия ствола головного мозга</kwd></kwd-group><kwd-group xml:lang="en"><kwd>petroclival meningioma</kwd><kwd>sphenopetroclival meningioma</kwd><kwd>brainstem compression</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">Cushing H., Eisenhardt L.
