Наряду с общепризнанными тепловыми методами абляции подкожных вен, при варикозном расширении привлекательным становится использование нетепловых и комбинированных методов. Благодаря разнообразию механизмов воздействия перспективной технологией для выполнения широкого спектра малоинвазивных внутрисосудистых операций, в т. ч. для лечения варикозной болезни, является низкочастотный ультразвук. Цель. Выяснить механизм действия нового метода эндовенозного лечения варикозной болезни вен нижних конечностей с использованием низкочастотного ультразвука и оценить его влияние на повреждение венозной стенки и облитерацию венозного просвета в животной модели. Материалы и методы. Тридцать четыре медиальные ветви центральной вены уха (ЦВУ) 17 кроликов были обработаны согласно протоколу хронического эксперимента. Шесть бедренных вен трех кроликов были обработаны в остром эксперименте и исследованы спустя 45 мин после воздействия. В хроническом эксперименте медиальные ветви ЦВУ были разделены на четыре группы в зависимости от времени наблюдения и типа воздействия: (0) 30 дней, контрольная процедура; (1) 60 дней, ультразвуковая абляция; (2) 95 дней, ультразвуковая абляция; (3) 138 дней, ультразвуковая абляция. Результаты. После ультразвукового воздействия облитерация венозного просвета наблюдалась в 29 из 30 медиальных ветвей ЦВУ (97%). Гистологическое исследование показало признаки теплового и механического повреждения венозной стенки, такие как абразия эндотелия и прогрессирование фиброза в tunica media и tunica adventitia. Окклюзированные сегменты состояли в основном из клеточного фиброзного материала. В остром эксперименте гистологически подтверждено повреждение всех слоев венозной стенки. Обсуждение. Ультразвуковая абляция приводит к однородному и равномерному повреждению венозной стенки. Результаты исследования позволяют выдвинуть гипотезу о том, что ультразвуковое воздействие приводит к венозной окклюзии вследствие аддитивного термомеханического механизма повреждения сосудистой стенки. Выводы. Эндовенозная ультразвуковая абляция приводит к схожей с эндовенозной лазерной абляции (ЭВЛА) и радиочастотной абляции (РЧА) картине теплового повреждения, а также к механическому разрушению эндотелия аналогично механохимической абляции (МХА). Спустя четыре месяца после ультразвуковой абляции частота окклюзии составила 90%.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Along with the generally accepted thermal methods of saphenous varicose veins ablation, the use of non-thermal and combined methods becomes attractive. Due to the variety of mechanisms of action, low-frequency ultrasound is a promising technology for performing a wide range of minimally invasive intravascular operations, including the treatment of varicose veins. Aim. To elucidate the mechanism of action of a novel endovenous ultrasound ablation method and evaluate its effect on vein wall injury and lumen occlusion in an animal model. Materials and methods. A total of 34 central ear vein (CEV) medial ramus were treated in 17 rabbits according to the follow-up protocol. Six femoral veins from three rabbits enrolled into the acute experiment were harvested 45 min after the procedure. All treated CEV medial ramus in the follow-up experiment were divided into four treatment groups with an observation time of: (0) 30 days, control procedure; (1) 60 days, ultrasound ablation; (2) 95 days, ultrasound ablation; (3) 138 days, ultrasound ablation. Results. Occlusion was achieved in all but one CEV medial ramus (29/30; 97%) treated with ultrasound. Histologic examination of treated veins showed heat- and mechanical-induced changes in the vein wall, such as abrasion of the endothelium and fibrotic lesions in the tunica media and tunica adventitia. The occluded segments consisted mainly of cellular fibrotic material. In the acute group, histological evidence of damage to all vessel wall layers was found. Discussion. Ultrasound ablation results in homogeneous and uniform damage to the venous wall. The results of this study suggest that the ultrasound treatment leads to venous occlusion by the additive thermomechanical mechanism of damage to the vessel wall. Conclusions. Endovenous ultrasound ablation showed a similar pattern of thermal damage as endovenous laser (EVLA) and radiofrequency ablation (RFA) and damage to the endothelium as mechanochemical ablation (MOCA). Four months after ultrasound ablation, the occlusion rate was 90%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндовенозная абляция</kwd><kwd>термооблитерация</kwd><kwd>нетермическая облитерация</kwd><kwd>низкочастотный ультразвук</kwd><kwd>варикозная болезнь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endovenous ablation</kwd><kwd>low-frequency ultrasound therapy</kwd><kwd>varicose veins</kwd><kwd>varicose veins therapy</kwd><kwd>saphenous vein</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">Gloviczki P, Lawrence PF, Wasan SM, Meissner MH, Almeida J, Brown KR et al.
