Despite the results of studies that have demonstrated the beneficial effect of endovascular therapy on functional outcome in IS, little research has been conducted on its impact on hospital mortality in IS, its timing and structure.</p><sec><title>Objective</title><p>Objective: to investigate hospital mortality in patients with IS and large cerebral artery occlusion, who underwent mechanical thrombectomy (MTE).</p></sec><sec><title>Material and methods</title><p>Material and methods. The retrospective study included data from 233 patients with IS and confirmed occlusion of a large cerebral artery (internal carotid artery, M1 and M2 segments of the middle cerebral artery, basilar artery) treated at the regional vascular center V.V. Veresaev Hospital, Moscow, 2018 and 2022. A comparison of hospital mortality in the group of patients who underwent MTE and the group of patients who received basic therapy was performed.</p></sec><sec><title>Results</title><p>Results. MTE was performed in 107 patients (46%); 126 patients (54%) received only basic therapy. The mortality rate of all patients included in the study was 44.2%. Among all deaths, the proportion of patients with MTE was only 7.2%, while the proportion of patients on basic therapy was 36.9% (p&lt;0.001). Mortality in the MTE group was four times lower than in the basic therapy group – 15.8% compared to 68.2% (p&lt;0.001). We observed that certain manifestations were significantly more frequent in the basic therapy group: cerebral edema (42% vs. 18.6%), hemorrhagic transformation (19.9% vs. 12.9%), venous thromboembolism (6.3% vs. 3.7%) and infectious complications (42.8% vs. 14.3%). The mortality of patients in the basic therapy group was higher on the first day, on days 2–3 and also on days 4–7, while no differences in mortality were observed after the first week of the disease.</p></sec><sec><title>Conclusion</title><p>Conclusion. Admission of a patient with IS within the “therapeutic window” creates the conditions for a significant reduction in hospital mortality and the incidence of stroke complications.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Окклюзия крупной церебральной артерии при ишемическом инсульте (ИИ) ассоциирована с высокой летальностью. Несмотря на результаты исследований, доказавших положительное влияние эндоваскулярной терапии на функциональный исход при ИИ, мало изучено ее влияние на госпитальную летальность от ИИ, ее сроки и структуру.</p><p>Цель исследования – изучить госпитальную летальность у пациентов с ИИ и окклюзией крупной церебральной артерии, которым проводилась механическая тромбэктомия (МТЭ).</p><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное исследование включены данные 233 пациентов с ИИ и подтвержденной окклюзией крупной церебральной артерии (внутренней сонной артерии, М1и М2-сегментов средней мозговой артерии, основной артерии), которые проходили лечение в региональном сосудистом центре больницы им. В.В. Вересаева г. Москвы в 2018 и 2022 гг. Проведено сравнение госпитальной летальности в группе пациентов, которым проводилась МТЭ, и группе пациентов, получавших базисную медикаментозную терапию.</p></sec><sec><title>Результаты</title><p>Результаты. МТЭ проводилась 107 пациентам (46%); 126 пациентов (54%) получали только базисную терапию. Летальность среди всех включенных в исследование пациентов составила 44,2%. Среди всех летальных исходов доля пациентов с МТЭ составила лишь 7,2%, тогда как доля пациентов, получавших базисную терапию, – 36,9% (p&lt;0,001). Летальность в группе МТЭ была в 4 раза ниже, чем в группе базисной терапии, – 15,8% против 68,2% (p&lt;0,001). В группе базисной терапии существенно чаще наблюдались отек головного мозга (42% против 18,6%), геморрагическая трансформация (19,9% против 12,9%), венозная тромбоэмболия (6,3% против 3,7%) и инфекционные осложнения (42,8% против 14,3%). Летальность пациентов группы базисной терапии была выше в 1-е сутки, на 2–3-и сутки, а также на 4–7-е сутки, тогда как после первой недели заболевания различий в летальности не наблюдалось.</p></sec><sec><title>Заключение</title><p>Заключение. Поступление пациента с ИИ в переделах «терапевтического окна» создает предпосылки для существенного снижения госпитальной летальности и частоты осложнений инсульта.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>механическая тромбэктомия</kwd><kwd>окклюзия крупной церебральной артерии</kwd><kwd>ишемический инсульт</kwd><kwd>госпитальная летальность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical thrombectomy</kwd><kwd>occlusion of a large cerebral artery</kwd><kwd>ischemic stroke</kwd><kwd>hospital mortality</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</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">Mentis AA, Dardiotis E, Grigoriadis N, et al.
