Изучить особенности ремоделирования коронарных артерий на основе анализа результатов оптической когерентной томографии после коррекции протяженных поражений коронарных артерий.</p></sec><sec><title>   Материал и методы</title><p>   Материал и методы. В настоящее исследование включены 80 пациентов, которым на базе РНПЦ «Кардиология» была выполнена эндоваскулярная коррекция протяженных (более 25 мм) поражений коронарных артерий. Пациенты в рандомном порядке были разделены на две группы: основная группа (ОГ) в количестве 40 пациентов – коррекция поражений с помощью биодеградируемого сосудистого скаффолда BVS Absorb и контрольная группа (КГ) в количестве 40 пациентов – коррекция поражений с помощью металлического стента с медикаментозным покрытием (эверолимус) Xience V/Xience Pro.</p></sec><sec><title>   Результаты</title><p>   Результаты. При проведении ОКТ исследования после процедуры имплантации площадь просвета внутри стента/скаффолда достоверно отличалась между группами и составляла 6,89 ± 1,93 мм2 в ОГ и 8,33 ± 2,94 мм2 в КГ. На 12-месячном контроле произошло достоверное снижение площади просвета в ОГ и КГ: до 6,13 ± 2,30 мм2 и 7,72 ± 3,11 мм2 соответственно. Анализ фрагментов имплантов показал достоверное различие в частоте встречаемости между ОГ и КГ мальаппозиционированных страт как исходно (1,29 % против 1,56 %), так и на 12-месячном контроле (0.19 % против 0.38 % в КГ). Количество протрудирующих страт в свою очередь было достоверно выше в ОГ (2,26 % против 0,14 %). Наблюдалась значимая разница в характере покрытия старт стентов/скаффолдов на 12-месячном контроле: неоинтима более равномерно распределялась в ОГ с минимальной толщиной 50 мкм против 40 мкм, при этом встречаемость непокрытых эндотелием страт была существенно ниже в ОГ, чем в КГ – 1,26 % против 12,6 %. В обеих группах было выявлено развитие эвагинаций сосудистой стенки в месте имплантации с существенными различиями между группами: в КГ было выявлено 2 таких пациента (5 %) с общим объёмом эвагинаций 5,4 мм3 и максимальной глубиной до 0,58 мм, в то время как в ОГ обнаружилось 12 таких пациентов (30 %) с общим объёмом эвагинаций 148,3 мм3 и максимальной глубиной до 1,64 мм. При этом у пациента из ОГ с максимальным объёмом, количеством и глубиной эвагинаций у единственного во всей выборке отмечен подтверждённый тромбоз в скаффолде.</p></sec><sec><title>   Заключение</title><p>   Заключение. Биодеградируемые скаффолды Absorb BVS имеют более ровное и полное покрытие неоинтимой на 12-месячном контроле в сравнении с металлическими стентами Xience V/Xience Pro. При этом артерии в местах имплантации скаффолдов Absorb BVS имеют значительно большую склонность к образованию выпячиваний сосудистой стенки – эвагинаций. Образованием этих эвагинаций можно объяснить большую склонность к тромбозам коронарных артерий в зоне установки импланта. По мере деградации скаффолда количество и объём эвагинаций снижается, таким образом можно ожидать и снижения числа возможных негативных исходов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Aim</title><p>   Aim. To examine the mechanisms of coronary artery vessel wall remodeling based on the analysis of the results of optical coherence tomography after correction of long coronary lesions.</p></sec><sec><title>   Material and methods</title><p>   Material and methods. This study includes 80 patients who underwent endovascular correction of long (more than 25 mm) coronary lesions at the Republican Scientific and Practical Centre “Cardiology”. The patients were randomly divided into two groups: the main group (MG) of 40 patients – lesion correction with biodegradable vascular scaffolds BVS Absorb and the control group (CG) of 40 patients – correction of lesions with drug-eluting metal stent Xience V/Xience Pro.</p></sec><sec><title>   Results</title><p>   Results. In OCT study after implantation procedure, the lumen area inside the stent/scaffold was statistically different between groups and was 6.89 ± 1.93 mm2 in the main group and 8.33 ± 2.94 mm2 in the control group. At the 12-month follow-up, there was a significant decrease in the lumen area in the main and control groups: to 6.13 ± 2.30 mm2 and 7.72 ± 3.11 mm2, respectively. Analysis of implant fragments revealed a significant difference in the incidence of strut malposition between the MG and CG both initially (1.29 % versus 1.56 %) and at 12-month follow-up (0.19 % versus 0.38 % in the control group). The number of protruding struts, in turn, was significantly higher in the main group (2.26 % versus 0.14 %). There was a significant difference in mechanisms of stents/scaffolds neointimal coverage at the 12-month control: the neointima was more smoothly distributed in the main group with minimum thickness of 50 µm versus 40 µm in control, while the incidence of uncovered struts was significantly lower in the main group than in the control group – 1.26 % versus 12.6 %. In both groups, the development of evaginations of the vascular wall at the site of implantation was revealed with significant differences between the groups: in the control group, 2 such patients (5 %) were identified with a total volume of evaginations of 5.4 mm3 and a maximum depth of up to 0.58 mm, while in the MG there was 12 such patients (30 %) with a total volume of evaginations of 148.3 mm3 and a maximum depth of up to 1.64 mm. Moreover, one patient from the main group with the maximum volume, number and depth of evaginations was the only one in the entire sample with confirmed thrombosis in the scaffold.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Scaffolds Absorb BVS have smoother and more complete neointimal coverage at 12-month follow-up compared to Xience V/Xience Pro metal stents. At the same time, arteries at the sites of implantation of Absorb BVS scaffolds have a significantly greater tendency to form big protrusions of the vascular wall – evaginations. The formation of these evaginations can explain greater tendency to thrombosis of the coronary arteries in the area of the implanted device. With scaffold degradation the number and volume of evaginations decreases, so we can expect a decrease in the number of possible negative outcomes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронарная ангиопластика</kwd><kwd>стентирование</kwd><kwd>протяженные поражения коронарных артерий</kwd><kwd>скаффолд</kwd><kwd>стент</kwd><kwd>оптическая когерентная томография</kwd><kwd>неонтима</kwd><kwd>эвагинации коронарных артерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scaffold</kwd><kwd>stent</kwd><kwd>coronary angioplasty</kwd><kwd>long coronary lesions</kwd><kwd>percutaneous intervention</kwd><kwd>optical coherence tomography</kwd><kwd>neointima</kwd><kwd>coronary artery evagination</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">Onuma Y., Dudek D., Thuesen L., Webster M., Nieman K., Garcia-Garcia H.M., Ormiston J.A., Serruys P.W.
