Embosphere microspheres with a diameter of 500–700 μm, hydrogel cylinders, endovascular adhesives such as ONYX 18 and cyanoacrylate, and embolization coils were used as embolization agents. The most common embolization procedure was preoperative embolization, followed by surgery within 24–48 h. However, in some cases, embolization was applied as an independent treatment method.</p> <p><bold>Results. </bold>The blood supply of head and neck hypervascular tumors depends on their location. In the majority of cases, it is the facial and maxillary arteries supply. Tongue tumors are supplied by the lingual arteries. Tumors of the periorbital region and nasal bridge are supplied by the angular and ocular arteries. Complete embolization of infantile hemangiomas was achieved in 87% of the cases.</p> <p><bold>Conclusion.</bold> Endovascular embolization was most commonly used in patients with arteriovenous malformations; it was performed both as an independent treatment option and in combination with surgery. In patients with hypervascular tumors, endovascular embolization was used preoperatively to reduce blood loss.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – определить эффективность эндоваскулярных методов лечения гиперваскулярных образований у детей и изучить осложнения их применения.</p> <p><bold>Материалы и методы.</bold> С 2012 по 2024 г. на базе НМИЦ ДГОИ им. Дмитрия Рогачева всего выполнено 207 эндоваскулярных эмболизаций различных образований головы и шеи у детей. В качестве эмболизационных агентов использовались микросферы Embosphere диаметром 500–700 мкм, гидрогелевые цилиндры, эндоваскулярные клеевые материалы ONYX 18 и цианоакрилат, эмболизационные спирали. В основном эмболизация проводилась в качестве предоперационной подготовки, после которой выполнялось хирургическое вмешательство в срок 24–48 ч. Однако в ряде случаев эмболизация выступала в качестве самостоятельного метода лечения.</p> <p><bold>Результаты.</bold> Гиперваскулярные образования головы и шеи имеют кровоснабжение в зависимости от их локализации. В основном это бассейн лицевой и верхнечелюстной артерий. Образования языка питаются из язычных артерий. Образования параорбитальной области, переносицы кровоснабжаются из угловой и глазной артерий. Полной эмболизации инфантильных гемангиом удалось достичь в 87% случаев.</p> <p><bold>Заключение.</bold> Наиболее востребованной эндоваскулярная эмболизация стала у пациентов с артериовенозными мальформациями, причем выполнялась она как самостоятельный метод, так и в комплексе с хирургическим вмешательством. При гиперваскулярных образованиях эндоваскулярная эмболизация использовалась в качестве предоперационной подготовки для уменьшения кровопотери.</p></trans-abstract><kwd-group xml:lang="en"><kwd>infantile hemangioma</kwd><kwd>arteriovenous malformation</kwd><kwd>venous malformation</kwd><kwd>endovascular embolization</kwd><kwd>endovascular occlusion</kwd><kwd>hypervascular tumor</kwd><kwd>embolization microspheres</kwd><kwd>adhesive compositions</kwd><kwd>embolization coils</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инфантильная гемангиома</kwd><kwd>артериовенозная мальформация</kwd><kwd>венозная мальформация</kwd><kwd>эндоваскулярная эмболизация</kwd><kwd>эндоваскулярная окклюзия</kwd><kwd>гиперваскулярная опухоль</kwd><kwd>эмболизационные микросферы</kwd><kwd>клеевые композиции</kwd><kwd>эмболизационные спирали</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gemmete J.J., Ansari S.A., McHugh J., Gandhi D.
