Стентирование бифуркационных поражений коронарных артерий требует постоянной адаптации к вызовам современной интервенционной кардиологии. Цель исследования. Изучить долгосрочные результаты хирургического лечения пациентов с бифуркационными поражениями коронарных артерий путём применения модифицированной методики провизионного стентирования. Материалы и методы. 90 пациентов с бифуркационными поражениями коронарных артерий были разделены на 3 группы методом простой рандомизации. В двух группах проведено provisional-стентирование по классическим методикам (дилатация боковой ветви и проксимальная оптимизация; kissing дилатация с проксимальной оптимизацией), в третьей группе применена модифицированная методика – локальная постдилатация ячейки стента с проксимальной оптимизацией. Через год после вмешательства были исследованы ангиографические параметры посредством ОКТ контроля, а также распространенность летальных случаев, острых нарушений мозгового кровообращения (ОНМК), тромбоза стента или артерий, повторного стентирования сосудов, инфаркта миокарда, серьезных неблагоприятных сердечнососудистых событий (MACE). Результаты. Инфаркт миокарда был выявлен у 6,6% пациентов в каждой группе. Необходимость повторной реваскуляризации целевого сосуда наблюдалась у 10% пациентов первой группы, 13,3% – второй, 6,6% третьей группы; повторная реваскуляризация другого сосуда была проведена 6,6% пациентов в первой и второй группе, и 3,3% в третьей. Неблагоприятные сердечно-сосудистые события (МАСЕ) происходили с приемлемо низкой частотой: у 13,3% в первой и второй группе, и у 10% пациентов, оперированных с применением модифицированной методики. По ангиографическим параметрам статистических различий между группами не обнаружено, однако, при оценке рестеноза в основной и боковой ветви, поздней потери просвета в ОВ и суммарной потери просвета в бифуркации в третьей группе отмечаются более низкие значения. Помимо этого, минимальный диаметр основной ветви был несколько выше в группе модифицированной методики. При повторном ОКТ контроле через 12 месяцев, сохраняются приемлемые значения минимального размера сосудов. Заключение. Описанная методика показала приемлемые отдаленные результаты при лечении бифуркационных поражений коронарных артерий, и может быть рассмотрена в качестве альтернативы классическим, общепринятым техникам стентирования.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Stenting of bifurcation lesions of the coronary arteries requires constant adaptation to the challenges of modern interventional cardiology. Objective. To study the long-term results of surgical treatment of bifurcation lesions of the coronary arteries using a modified provisional stenting technique. Materials and methods. 90 patients with bifurcation lesions of the coronary arteries were divided into 3 groups by simple randomization. In two groups, provisional stenting was performed using classical techniques (side branch dilation and proximal optimization; kissing dilation with proximal optimization), in the third group, a modified technique was used – local postdilation of the stent cell with proximal optimization. One year after the intervention, angiographic parameters were studied using OCT control, as well as the incidence of deaths, acute cerebrovascular accidents (CVA), stent or arterial thrombosis, re-stenting of vessels, myocardial infarction, and major adverse cardiovascular events (MACE). Results. Myocardial infarction was detected in 6.6% of patients in each group. The need for repeated revascularization of the target vessel was observed in 10% of patients in the first group, 13.3% in the second, and 6.6% in the third group; repeated revascularization of another vessel was performed in 6.6% of patients in the first and second groups, and 3.3% in the third. Adverse cardiovascular events (MACE) occurred with an acceptably low frequency: in 13.3% in the first and second groups, and in 10% of patients operated on using the modified technique. No statistical differences were found between the groups in terms of angiographic parameters; however, lower values were observed in the third group when assessing restenosis in the main and side branches, late lumen loss in the OB, and total lumen loss in the bifurcation. In addition, the minimum diameter of the main branch was slightly higher in the modified technique group. Repeated OCT monitoring after 12 months showed acceptable values of the minimum vessel size. Conclusion. The described technique showed acceptable long-term results in the treatment of bifurcation lesions of the coronary arteries and can be considered as an alternative to classical, generally accepted stenting techniques.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бифуркационные поражения</kwd><kwd>коронарные артерии</kwd><kwd>стентирование</kwd><kwd>проксимальная оптимизация</kwd><kwd>kissing дилатация</kwd><kwd>provisional – стентирование</kwd><kwd>постдилатация ячейки стента</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bifurcation lesions</kwd><kwd>coronary arteries</kwd><kwd>stenting</kwd><kwd>proximal optimization</kwd><kwd>kissing dilation</kwd><kwd>provisional stenting</kwd><kwd>stent cell postdilation</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">Chiabrando JG, Lombardi M, Vescovo GM, et al.
