С целью профилактики тромботических осложнений после эндоваскулярного закрытия открытого овального окна (ООО) назначается двойная антиагрегантная терапия (ДААТ) с переходом на монотерапию ацетилсалициловой кислотой (АСК). Данные препараты повышают риск кровотечений, в то время как ранняя отмена терапии способна привести к повторным ишемическим инсультам (ИИ) и транзиторным ишемическим атакам (ТИА). Эффективная и безопасная длительность ДААТ точно не установлена из-за малой доказательной базы.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: сравнить эффективность и безопасность длительной и сокращенной по времени антиагрегантной терапии (ААТ) у пациентов, прошедших эндоваскулярное закрытие ООО.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 239 пациентов, прошедших эндоваскулярное закрытие ООО. Клинико-анамнестическая характеристика выборки: 140 (58,58%) женщин, медиана возраста – 43,00 [35,00; 52,00] года, 173 (72,38%) пациента перенесли ИИ, 66 (27,62%) – ТИА. Пациенты принимали ААТ по двум схемам: длительная ДААТ (клопидогрел + АСК) в течение 6 мес. с переходом на монотерапию АСК до 5 лет; сокращенная по длительности схема (ДААТ и монотерапия АСК до 6 мес.) Пациенты находились под наблюдением 38,23 [22,20; 48,67] мес. и были разделены на 2 группы. В первую группу вошли 145 (60,70%) пациентов с длительной ДААТ, во вторую – 94 (39,30%) пациента, которые принимали ДААТ по сокращенной схеме.</p></sec><sec><title>Результаты</title><p>Результаты. Различия между группами пациентов с длительной и сокращенной ДААТ по клинико-анамнестическим и интраоперационным характеристикам, частоте развития осложнений, состоянию в раннем послеоперационном периоде и отдаленной перспективе отсутствуют. Для всех параметров сравнения значение p ˃ 0,05. Продолжительность наблюдения для группы с длительной ДААТ составила 38,65 [23,14; 48,43] мес., 110 (75,86%) пациентов принимали клопидогрел в течение 6 мес., АСК – до 60 мес. За время наблюдения зафиксировано 6 (4,35%) случаев кровотечений, в том числе 1 (0,72%) крупное, 1 (0,72%) случай ИИ и 1 (0,72%) ТИА. Продолжительность наблюдения для группы с сокращенной длительностью ДААТ составила 35,70 [21,43; 51,67] мес. (р = 0,4088). Всего 74 (78,72%) пациента принимали клопидогрел в течение 6 мес. (р = 0,8970), а 68 (72,34%) прекратили терапию АСК через 6 мес. после эндоваскулярного закрытия ООО. За время наблюдения зафиксировано 1 (1,18%) малое кровотечение и 1 (1,18%) ИИ (р ˃ 0,05).</p></sec><sec><title>Выводы</title><p>Выводы. Длительная и сокращенная до 6 мес. ААТ имеет сравнимую эффективность в профилактике тромботических осложнений после эндоваскулярного закрытия ООО. При приеме ААТ наблюдается тенденция к увеличению риска развития кровотечений, вероятность которых повышается с длительностью лечения. Решение о продолжительности ААТ должно приниматься индивидуально на основании риска тромбообразования и кровотечений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. In order to prevent thrombotic complications after endovascular closure of patent foramen ovale (PFO), dual antiplatelet therapy (DAPT) is prescribed with a switch to acetylsalicylic acid monotherapy. These drugs increase the risk of bleeding, while early withdrawal of therapy can lead to recurrent ischemic stroke (IS) and transient ischemic attack (TIA). The effective and safe duration of DAPT has not been accurately established due to the small evidence base.</p></sec><sec><title>Aim</title><p>Aim. To compare the efficacy and safety of long-term and shortened antiplatelet therapy (AAT) in patients undergoing endovascular closure of PFO.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. 239 patients who underwent endovascular closure of PFO were included in the study. Clinical and anamnestic characteristics of the sample: 140 (58.58%) women, mean age 43.00 [35.00; 52.00] years, 173 (72.38%) patients had an IS and 66 (27.62%) TIA. Patients were taking APT according to two regimens. Prolonged in duration included DAPT (clopidogrel + acetylsalicylic acid) for 6 months with a switch to acetylsalicylic acid monotherapy for up to 5 years. Shortened duration included DAPT and acetylsalicylic acid monotherapy for up to 6 months. Patients were followed up for 38.23 [22.20; 48.67] months and were divided into 2 groups. The first group included 145 (60.70%) patients with prolonged duration of DAPT and the second group included 94 (39.30%) patients who were receiving DAPT according to the shortened duration regimen.</p></sec><sec><title>Results</title><p>Results. There were no differences between the groups of patients with prolonged and shortened duration of DAPT in terms of clinical and anamnestic and intraoperative characteristics, complication rate, early postoperative period and long-term follow-up. The pvalue ˃ 0.05 for all comparison parameters. The duration of follow-up for the group with prolonged DAPT duration was 38.65 [23.14; 48.43] months, 110 (75.86%) patients received clopidogrel for 6 months, acetylsalicylic acid for 60 months. During follow-up, there were 6 (4.35%) bleeding events, including 1 (0.72%) major bleeding event, 1 (0.72%) IS, and 1 (0.72%) TIA. The duration of follow-up for the group with shortened DAPT duration was 35.70 [21.43; 51.67] months (p = 0.4088). A total of 74 (78.72%) patients were received clopidogrel for 6 months (p = 0.8970), and 68 (72.34%) discontinued acetylsalicylic acid therapy 6 months after endovascular closure of the PFO. There was 1 (1.18%) minor bleeding and 1 (1.18%) IS during follow-up (p ˃ 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Prolonged duration and shortened to 6 months APT have comparable efficacy in preventing thrombotic complications after endovascular closure of the PFO. Administration of APT may risk of bleeding, the likelihood of which increases with the duration of treatment. The decision on the duration of APT should be made individually based on the risk of thrombosis and bleeding.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>двойная антиагрегантная терапия</kwd><kwd>эндоваскулярное закрытие открытого овального окна</kwd><kwd>открытое овальное окно</kwd><kwd>клопидогрел</kwd><kwd>ацетилсалициловая кислота</kwd><kwd>профилактика тромбообразования</kwd><kwd>криптогенный инсульт</kwd><kwd>транзиторная ишемическая атака</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endovascular closure of patent foramen ovale</kwd><kwd>dual antiplatelet therapy</kwd><kwd>clopidogrel</kwd><kwd>acetylsalicylic acid</kwd><kwd>cryptogenic stroke</kwd><kwd>transient ischemic attack</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">Geisler T., Jorbenadze R., Popov A.F., Mueller K.L., Rath D., Droppa M. et al.
