Лучшие результаты, по сравнению с другими кондуитами, демонстрирует левая внутренняя грудная артерия. Большинство исследований, посвященных сравнительным результатам проходимости шунтов, опираются на коллективный опыт клиник с использованием различных методов выполнения операций, как с искусственным кровообращением, так и на «работающем сердце». </p><p>Цель исследования – провести сравнительный анализ отдалённой проходимости аутовенозного аортокоронарного и маммарокоронарного шунтов в переднюю межжелудочковую артерию после коронарного шунтирования, выполненного единственным хирургом на «работающем сердце» доступом из срединой стернотомии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. С сентября 1997 года по декабрь 2024 года выполнено 7422 операции коронарного шунтирования на «работающем сердце». Из них 6829 (92 %) операций проведены с мая 2001 года с использованием доступа из срединной стернотомии.  У 1059 больных  (15,5 %) выполнена контрольная шунтография. Из 1059 больных, прошедших шунтографию, выделена группа больных (n = 843), оперированных  одним хирургом. Для анализа отдаленных результатов проходимости шунтов сформированы две группы больных. В первой группе больных выполнено  аутовенозное аортокоронарное шунтирование (n = 652), а во - второй группе больных – маммарокоронарное шунтирование  передней межжелудочковой артерии (n = 191).</p></sec><sec><title>Результаты</title><p>Результаты.  отдаленная проходимость  в сроки 5, 10, 15 лет маммарокоронарного  шунта в  переднюю межжелудочковою артерию недостоверно лучше (р=0,09), чем аутовенозного  шунта в переднюю межжелудочковою артерию  и составляет соответственно 91 %,77 %,56 % и 88 %,70 %,41 %.</p></sec><sec><title>Заключение</title><p>Заключение.  При выполнении операции коронарного шунтирования  передней межжелудочковой артерии  на «работающем сердце» доступом из стернотомии одним хирургом отдаленная проходимость  аутовенозного шунта может быть сравнима с маммарокоронарным шунтированием.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. The long-term success of coronary artery bypass grafting is largely determined by the late patency of bypass grafts. Among all conduits, the left internal mammary artery consistently shows the best outcomes. However, most comparative studies are based on heterogeneous institutional experiences and include both on-pump and off-pump techniques. There is a lack of large-scale, single-surgeon series comparing long-term patency of mammary and autologous vein grafts to the anterior interventricular artery using a uniform off-pump sternotomy approach.</p></sec><sec><title>Aim</title><p>Aim. To compare, by means of control graft angiography, the long-term patency of autologous vein aortocoronary bypasses and mammary artery bypasses to the anterior interventricular artery following off-pump coronary surgery through a median sternotomy, all performed by one surgeon.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. Between September 1997 and December 2024, 7422 off-pump coronary bypass operations were performed in the department. From May 2001 onward, 6829 of these (92 %) were carried out via median sternotomy. Control angiography was undertaken in 1059 patients (15.5 %). For the present analysis, we selected 843 patients operated on by a single surgeon. Among them, 652 received an autologous vein aortocoronary graft to the anterior interventricular artery, and 191 received a mammary artery graft to the same vessel.</p></sec><sec><title>Results</title><p>Results. The patency rates for mammary artery grafts at 5, 10, and 15 years were 91 %, 77 %, and 56 %, respectively, versus 88 %, 70 %, and 41 % for vein grafts. These differences were not statistically significant (p = 0.09).</p></sec><sec><title>Conclusion</title><p>Conclusion. In off-pump coronary bypass grafting to the anterior interventricular artery via sternotomy performed by a single surgeon, the long-term patency of autologous vein grafts may be comparable to that of mammary artery grafts.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>левая внутренняя грудная артерия</kwd><kwd>аутовена</kwd><kwd>передняя межжелудочковая артерия</kwd><kwd>коронарное шунтирование на «работающем сердце»</kwd><kwd>проходимость шунта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>saphenous vein grafts</kwd><kwd>left internal mammary artery</kwd><kwd>left anterior descending coronary artery</kwd><kwd>beating heart</kwd><kwd>graft patency</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">Alboom M., Browne A., Sheth T. et al.
