Эндопротезирование грудной аорты в настоящее время характеризуется активным развитием и расширением спектра клинических показаний. К ним относятся расслоение аорты типа B по классификации Stanford, поражение дуги аорты (не-A, не-B тип) с применением эндоваскулярных и гибридных методик (включая дебраншинг), а также аневризмы, пенетрирующие атеросклеротические язвы и разрывы грудной аорты.Цель исследования. Изучить механические характеристики различных типов стент-графтов и оценить их возможное клиническое значение.Материалы и методы. В исследование включены два типа грудных эндопротезов, представленных на отечественном рынке медицинских изделий, различающихся типом покрытия: политетрафторэтиленовым (ПТФЭ) и полиэстеровым. Учитывая, что при планировании эндопротезирования с целью обеспечения герметичности применяется оверсайзинг (превышение диаметра эндопротеза относительно нативного сосуда), проведена экспериментальная оценка степени радиального сжатия стент-графтов с использованием механического пресса. Оценивалась сила, необходимая для деформации устройств, как косвенный показатель радиальной силы, действующей на стенку аорты.Результаты. Установлено, что минимальные значения радиальной силы характерны для проксимальных непокрытых сегментов эндопротезов с последующим ее увеличением в дистальном направлении покрытой части эндопротеза. Максимальные значения давления зарегистрированы у стент-графта с монофиламентным полиэстеровым покрытием в дистальных отделах, тогда как минимальные ‒ у устройства с ПТФЭ-покрытием в проксимальной зоне.Заключение. Радиальная нагрузка в области покрытых сегментов стент-графта превышает таковую в непокрытой проксимальной части. Полученные данные свидетельствуют о целесообразности позиционирования проксимального отдела эндопротеза в максимально неизмененном участке аорты с целью снижения риска развития осложнений.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Thoracic endovascular aortic repair (TEVAR) is rapidly evolving, with expanding clinical indications. These include Stanford type B aortic dissection, aortic arch pathology (non-A, non-B type) managed with endovascular and hybrid techniques (including debranching), as well as aneurysms, penetrating atherosclerotic ulcers, and thoracic aortic ruptures.Objective. To investigate the mechanical properties of different types of stent grafts and to assess their potential clinical implications.Materials and Methods. The study included two types of thoracic endografts available on the available commercially medical device market, differing by graft material: polytetrafluoroethylene (PTFE) and polyester. Considering that oversizing (i.e., selecting an endograft diameter exceeding that of the native vessel) is used during procedural planning to ensure sealing, an experimental assessment of the degree of radial compression of stent grafts was performed using a mechanical press. The force required to deform the devices was evaluated as an indirect indicator of radial force on the aortic wall.Results. Minimal radial force values were observed in the proximal uncovered segments of the endografts, followed by an increase toward the distal direction within the covered portion. The radial force values were recorded in the distal segments of the stent graft with monofilament polyester covering, whereas the lowest values were observed in the proximal region of the PTFE-covered device.Conclusion. Radial load in the covered segments of the stent graft exceeds that in the uncovered proximal portion. This finding supports the need to position the proximal part of the endograft within the least diseased segment of the aorta to reduce the risk of complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механические свойства эндопротезов</kwd><kwd>осложнения эндопротезирования</kwd><kwd>оверсайзинг</kwd><kwd>политетрафторэтилен</kwd><kwd>полиэстер</kwd><kwd>радиальная сила</kwd><kwd>ретроградное расслоение</kwd><kwd>стент-графт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical properties of endografts</kwd><kwd>complications of endovascular repair</kwd><kwd>oversizing</kwd><kwd>polytetrafluoroethylene</kwd><kwd>polyester</kwd><kwd>radial force</kwd><kwd>retrograde dissection</kwd><kwd>stent graft</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">Koechlin L, Schuerpf J, Bremerich J, et al.
