Функциональность коронарных шунтов после хирургической реваскуляризации миокарда у пациентов с ишемической болезнью сердца напрямую зависит от состояния целевых коронарных артерий. При наличии распространенного и диффузного атеросклеротического поражения или микроциркуляторных дисфункций отмечается высокая частота дисфункций коронарных шунтов уже в ближайшее время. В некоторых случаях дисфункция шунта может привести к выраженной гемодинамической нестабильности, сопровождающейся острыми нарушениями кровообращения.</p></sec><sec><title>Цель работы</title><p>Цель работы: оценить функцию коронарных шунтов при реваскуляризации миокарда с использованием метода ультразвуковой флоуметрии у пациентов, имеющих и не имеющих в анамнезе множественные чрескожные коронарные вмешательства (ЧКВ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное исследование включены 47 пациентов, подвергшихся операции аортокоронарного шунтирования. Всего было выполнено 145 коронарных шунтов. Все пациенты были разделены на 2 группы. В 1-ю группу (группа ЧКВ) были включены пациенты после множественных предшествующих ЧКВ (n = 25; 74 коронарных шунта), 2-ю группу (без ЧКВ) составили пациенты без предшествующих ЧКВ (n = 22; 71 коронарный шунт). Всем пациентам интраоперационно выполнена ультразвуковая флоуметрия коронарных шунтов с помощью системы VeriQ (Medistim, Норвегия).</p></sec><sec><title>Результаты</title><p>Результаты. При анализе статуса коронарных шунтов у пациентов после множественных ЧКВ был отмечен значимо низкий показатель средней объемной скорости кровотока (29,50000-0002-0288-41918,3 и 48,2 ± 11,6 мл/мин соответственно, p = 0,0001) и более низкое диастолическое наполнение (55,2 ± 8,2 и 71,9 ± 7,1%, p = 0,0001). Также в группе пациентов после множественных ЧКВ было 2 (2,7%) случая ревизии дистального анастомоза по поводу высокого пульсативного индекса и низкой объемной скорости кровотока. При этом в группе без ЧКВ таких событий отмечено не было.</p></sec><sec><title>Выводы</title><p>Выводы. Наличие в анамнезе предшествующих ЧКВ снижает функциональный статус коронарных шунтов.</p></sec></abstract><trans-abstract xml:lang="en"><p>The functionality of coronary bypass grafts after surgical myocardial revascularization in patients with coronary heart disease directly depends on the state of the target coronary arteries. In the presence of widespread and diff use atherosclerotic lesions or microcirculatory dysfunctions, a high frequency of coronary bypass dysfunctions is noted in the near future. In some cases, shunt dysfunction can lead to severe hemodynamic instability, accompanied by acute circulatory disorders.</p><sec><title>Aim</title><p>Aim: To assess the function of coronary bypass grafts during myocardial revascularization using the method of ultrasonic flowmetry in patients with and without a history of multiple percutaneous coronary interventions (PCI).</p></sec><sec><title>Material and methods</title><p>Material and methods. The retrospective study included 47 patients who underwent coronary artery bypass surgery. A total of 145 coronary bypass grafts were performed. All patients were divided into 2 groups. Group 1 (PCI group) included patients after multiple previous PCI (n = 25; 74 coronary bypass grafts), group 2 (without PCI) included patients without previous PCI (n = 22; 71 coronary bypass grafts). All patients underwent intraoperative ultrasonic flowmetry of coronary bypass grafts using the VeriQ system (Medistim, Norway).</p></sec><sec><title>Results</title><p>Results. When analyzing the status of coronary bypass grafts in patients after multiple PCI, a significantly low mean volumetric blood flow rate was noted (29.5 ± 8.3 ml/min and 48.2 ± 11.6 ml/min, respectively, p = 0.0001) and lower diastolic filling (55.2 ± 8.2% and 71.9 ± 7.1%, p = 0.0001). Also in the group of patients after multiple PCI, there were 2 (2.7%) cases of revision of the distal anastomosis due to a high pulsatile index and low volumetric blood flow velocity. However, no such events were noted in the group without PCI.</p></sec><sec><title>Conclusions</title><p>Conclusions. Previous percutaneous coronary interventions are compromising factors for the state of the coronary bed, which reduces the functional status of coronary bypass grafts and may increase the perioperative risk of surgical myocardial revascularization.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>коронарное шунтирование</kwd><kwd>ультразвуковая флоуметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic heart disease</kwd><kwd>coronary artery bypass grafting</kwd><kwd>transit time flow measurement</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 F.J., Sousa-Uva M., Ahlsson A., Alfonso F., Banning A.P., Benedetto U. et al.; ESC Scientific Document Group. 2018 ESC/EACTS Guidelines on myocardial revascularization.
