Изучить показатели интраоперационной ультразвуковой флоуметрии (ИУФ) по коронарным шунтам у больных с диффузным поражением при различном диаметре целевых коронарных артерий.</p></sec><sec><title>Материал и  методы</title><p>Материал и  методы. Включено 150 пациентов с  диффузным поражением коронарных артерий. Всем больным выполнено коронарное шунтирование (КШ) с  использованием микрохирургической техники, оценены параметры ИУФ. Сформировано 3 группы коронарных шунтов в зависимости от диаметра целевых коронарных артерий (КА): группа 1 сформирована из шунтов к  КА ≤1  мм (n=101), группа 2 — к КА 1-1,5 мм (n=138), группа 3 — к КА ≥1,5 мм (n=308). Выполнен сравнительный анализ параметров ИУФ в  указанных группах.</p></sec><sec><title>Результаты</title><p>Результаты. Большинство исследуемых представлено мужчинами (76%), средний возраст больных составил 62,9±7,6 лет. На госпитальном этапе зарегистрирован 1 летальный исход, из значимых сердечно-сосудистых событий диагностировано 2 периоперационных инфаркта миокарда (1,3%) и 1 нарушение мозгового кровообращения (0,7%). Анализ результатов ИУФ продемонстрировал худшие параметры гемодинамики по коронарным шунтам и, соответственно, более высокую частоту субоптимальной функции шунтов в группе 1; результаты ИУФ в группах 2 и 3 были сопоставимы. Дополнительный анализ с объединением групп 2 и 3 позволил сформулировать суждение о  негативном влиянии малого калибра целевых КА (≤1  мм) на достижение оптимальных параметров гемодинамики по коронарным шунтам (отношение шансов =2,1, 95% доверительный интервал: 1,2-3,8, p=0,011).</p></sec><sec><title>Заключение</title><p>Заключение. Диффузный коронарный атеросклероз с диаметром целевых КА ≤1 мм существенно увеличивает риск субоптимальной функции коронарных шунтов и требует рассмотрения усиления мер вторичной профилактики. Использование ИУФ демонстрирует высокую эффективность КШ артерий диаметром ≥1-1,5 мм с использованием микрохирургической техники.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the parameters of transit time flow measurement (TTFM) for coronary bypass grafts in patients with diffuse lesions with different diameter of target coronary arteries.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 150 patients with diffuse coronary artery disease. All patients underwent microscope-assisted coronary artery bypass grafting (CABG), during which the TTFM parameters were evaluated. Depending on the diameter of target coronary arteries, patients were divided into 3 groups: group 1 included grafts to arteries ≤1 mm (n=101), group 2 — 1-1,5 mm (n=138), group 3 — ≥1,5 mm (n=308). Comparative analysis of TTFM parameters was performed.</p></sec><sec><title>Results</title><p>Results. Mostly participants were male (76%); mean age was 62,9±7,6 years. During hospitalization, we recorded 1 death, 2 perioperative myocardial infarctions (1,3%) and 1 cerebrovascular accident (0,7%). TTFM analysis showed the worst hemodynamic parameters and a higher rate of suboptimal function in group 1; blood flow parameters were comparable in groups 2 and 3. The additional analysis in group 1 and combined groups 2 and 3 allows us to make an opinion about the negative impact of coronary artery diameter less than 1 mm on optimal blood flow through the grafts (odds ratio=2,1, 95% confidence interval, 1,2-3,8, p=0,011).</p></sec><sec><title>Conclusion</title><p>Conclusion. Diffuse coronary atherosclerosis with a diameter of target coronary arteries less than 1 mm significantly increase the risk of suboptimal graft function that requires considering more aggressive secondary prevention. TTFM demonstrate high effectiveness of microscope-assisted CABG in target coronary artery diameter of 1-1,5 mm and higher.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронарное шунтирование</kwd><kwd>интраоперационная ультразвуковая флоуметрия</kwd><kwd>диффузное поражение коронарных артерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary artery bypass grafting</kwd><kwd>transit time flow measurement</kwd><kwd>diffuse coronary atherosclerosis</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">Neumann FJ, Sousa-Uva M, Ahlsson A, et al. 2018 ESC/EACTS Guidelines on myocardial revascularization.
