Выполнен анализ 214 шунтов. Первый этап флоуметрии проводили на остановленном сердце спроксимальной петлевой пробой и без нее; второй этап – после отлучения от аппарата искусственного кровообращения (ИК); третий этап – после инактивации гепарина до закрытия раны грудной клетки.</p></sec><sec><title>Результаты</title><p>Результаты. Среди 214 трансплантатов при флоуметрии в 4,2% (n = 9) случаев был выявлен недостаточный кровоток.Техническая хирургическая погрешность была подтверждена в этих шунтах во время их ревизии. В 2,8% (n = 6) случаев были отмечены неоптимальные параметры флоуметрии во время первого измерения, где в 2,3% (n = 5) случаев неоптимальный кровоток верифицирован с использованием проксимальной петлевой пробы на целевой коронарной артерии и в 0,47% (n = 1) наблюдений – без пробы. В 0,47% (n = 1) случаев обнаружен неадекватный кровоток во время второго измерения, что подтвердило технические ошибки в проксимальных анастомозах. В 0,93% (n = 2) случаев обнаружены низкие параметры кровотока во время третьего измерения, что было связано с перегибами шунтов из-за их чрезмерной длины. Все хирургические погрешности были исправлены сразу на этапе их верификации.</p></sec><sec><title>Выводы</title><p>Выводы. Стратегия трехэтапной оценки флоуметрии дает возможность обеспечить и документировать адекватнуюфункциональность коронарных шунтов на всех этапах операции. Это позволяет вовремя верифицировать и сразуисправить любые технические проблемы с коронарными шунтами. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title> Purpose</title><p> Purpose. To determine the role of three-stage ultrasonic flowmetry of coronary bypass grafts for the purpose of early verification of technical errors during coronary bypass surgery.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A total of 214 grafts were analyzed. The first stage of flowmetry was performed on the arrested heart with and without proximal loop test; the second stage was performed after weaning patient from the heart-lung machine; the third was done after inactivation of heparin until the closure of the chest wound.</p></sec><sec><title>Results</title><p>Results. Among 214 grafts, flowmetry revealed insufficient blood flow in 4.2% (n = 9) of cases. Technical surgical errors in these shunts were confirmed during their revision. During the first measurement, non-optimal flowmetry parameters were observed in six cases (2.8%) including five cases (2.3%) where non-optimal blood flow was verified using a proximal loop test on the target coronary artery and one case (0.47%), which was not tested. Inadequate blood flow was found in one case (0.47%) during the second measurement, which confirmed technical errors in the proximal  anastomoses. Low blood flow parameters were found in two cases (0.93%) during the third measurement, which was associated with bending of the shunts due to their excessive length. All surgical errors were corrected immediately at the stage of their verification.</p></sec><sec><title>Conclusion</title><p>Conclusion. The strategy of three-stage flowmetry assessment makes it possible to ensure and document the adequate functionality of coronary bypass grafts at all stages of the operation. This allows for timely verification and immediate correction of any technical problems with coronary bypass grafts. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ультразвуковая флоуметрия</kwd><kwd>функциональность шунтов</kwd><kwd>коронарное шунтирование</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">Thuijs D.J.F.M., Bekker M.W.A., Taggart D.P., Kappetein A.P., Kieser T.M., Wendt D. et al.
