Динамику размеров КМ отслеживали путем проведения контрольных магнитно-резонансных томографий (МРТ) у всех пациентов (через 1, 2, 3 и более года). Группу сравнения составили 20 пациентов с естественным течением КМ, информацию о котором получали также путем телефонного опроса.</p></sec><sec><title>Результаты</title><p>Результаты. При первой контрольной МРТ через 1 год после РХГН размеры КМ уменьшились у 66,6 % пациентов. Последующие контрольные МРТ выявили увеличение доли КМ, отреагировавших на облучение, и продолжение уже начавшихся процессов их склерозирования. Быстрый темп уменьшения размеров КМ после РХГН гарантировал низкую вероятность повторных кровоизлияний, которые произошли у 3 пациентов с медленным уменьшением размеров КМ. Сокращение объема КМ создавало условия для лучшего клинического восстановления, которое при телефонном опросе установлено у 64,5 % пациентов.</p></sec><sec><title>Заключение</title><p>Заключение. Преобладание доли пациентов с уменьшившимися КМ (72,4, %) и улучшением общего состояния позволяет рассматривать РХГН как равноценный, а не второстепенный метод лечения субтенториальных КМ. Среди пациентов с замедленной реакцией КМ на облучение, даже несмотря на сохраняющийся риск повторных кровоизлияний, не зарегистрировано летальных исходов и случаев глубокой инвалидизации.</p></sec><sec><title>Ключевые слова</title><p>Ключевые слова: кавернозная мальформация, повторные кровоизлияния, радиохирургия, гамма-нож</p></sec></abstract><trans-abstract xml:lang="en"><p>The study objective is to estimate treatment success of gamma knife radiosurgery (GKRS) in the patients with subtentorial cavernous malformation (CM) based on follow-up data and magnetic resonance imaging (MRI).</p><sec><title>Materials and methods</title><p>Materials and methods. The long-term follow-up of GKRS in 87 patients with CM in brain stem and cerebellum was obtained. The clinical outcomes were observed using phone-based SF-36 health status survey in 55 patients. MRI data was collected before and after GKRS within 1, 2, 3 and more years. The natural history of CM without GKRS were observed in 20 patients.</p></sec><sec><title>Results</title><p>Results. The 1st year MRI observation after GKRS have demonstrated CM reduction in 66,6 % patients. At subsequent MRI-control the tendency of increase in number of CM, reacted on irradiation, and continuation of started processes of its sclerotization is revealed. The fast reduction of CM sizes was associated with lower risk of recurrent hemorrhages, that were observed in 3 patients with slow reduction. The CM reduction was also associated with good clinical outcomes, that was observed in 64,5 % patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. The presence of CM reduction (72,4 %) and good clinical outcome in suggests GKRS as a frontline treatment modality in patient with subtentorial CM. In the cases of slow rate of treatment response and unexpired risk of repeated hemorrhage no mortality and significant disability were mentioned.</p></sec></trans-abstract><kwd-group xml:lang="en"><kwd>cavernous malformation</kwd><kwd>repeated hemorrhage</kwd><kwd>radiosurgery</kwd><kwd>gamma knife</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">Белоусова О.Б., Коновалов А.Н.
