A prospective observational clinical comparative study was conducted. The main group consisted of 64 women with ВОН, with singleton (subgroup I1, n = 38) and multiple (dichoric diamniotic twins) pregnancies (subgroup I2, n = 26) following IVF, used low molecular weight heparins (LMWH). Control group: 35 pregnant women with singleton pregnancies (subgroup C1) and 35 with twins (subgroup C2) following IVF. Hemostasis was assessed by measuring APTT (activated partial thromboplastin time), PT (prothrombin time), TT (thrombin time), fibrinogen, antithrombin, protein C, protein S, protein C function (test РrоС Global); D-dimer; platelet aggregation with ristocetin, ADP (adenosine-5-diphosphate) and collagen, anti-Xa activity, thromboelastography, antiphospholipid antibodies and genetic thrombophilia.</p></sec><sec><title>Results</title><p>Results. Post-IVF pregnancy in patients with ВОН and the risk of thrombosis during controlled anticoagulant prophylaxis was accompanied by lowered incidence of complications compared with control group: impaired uteroplacental blood flow was observed in 7.8 % vs. 24.3 % (p &lt; 0.05), fetal growth restriction – in 3.1 % vs. 12.9 % (p &lt; 0.05), preeclampsia – in 6.3 % vs. 20.0 % (p &lt; 0.05), threat of pregnancy termination in the first trimester – in 14.1 % vs. 28.6 % (p &lt; 0.05), in the second trimester – in 7.8 % vs. 21.4 % (p &lt; 0.05). The controlled LMWH use was associated with favorable pregnancy course and outcome. Assessing dynamics of hemostasis parameters during anticoagulant and antiplatelet therapy allowed to substantiate the need to increase LMWH dose during pregnancy progression, to assess its adequacy and safety.</p></sec><sec><title>Conclusion</title><p>Conclusion. The increased hypercoagulation upon pregnancy progression requires monitoring the adequacy of anticoagulation therapy in risk groups, especially in post-IVF multiple pregnancies.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: оценить клиническое значение контроля за гемостазом при проведении антикоагулянтной терапии у пациенток с беременностью после экстракорпорального оплодотворения (ЭКО) и отягощенным акушерским анамнезом (ОАА).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено проспективное обсервационное клиническое сравнительное исследование. Основную группу составили 64 женщины с ОАА, с одноплодной (подгруппа И1, n = 38) и многоплодной (дихориальная диамниотическая двойня) беременностью (подгруппа И2, n = 26) после ЭКО, получавшие терапию низкомолекулярными гепаринами (НМГ). Контрольную группу составили 35 беременных с одноплодной беременностью (подгруппа С1) и 35 с двойней (подгруппа С2) после ЭКО. Исследования системы гемостаза включало определение АЧТВ (активированное частичное тромбопластиновое время), ПВ (протромбиновое время), ТВ (тромбиновое время), измерение уровня фибриногена, антитромбина, протеина С, протеина S, функции протеина С (test РrоС Global); D-димера; агрегации тромбоцитов с ристоцетином, АДФ (аденозин-5-дифосфата) и коллагеном; анти-Ха активности, тромбоэластографию, определение антифосфолипидных антител и генетической тромбофилии.</p></sec><sec><title>Результаты</title><p>Результаты. Беременность после ЭКО у пациенток с ОАА и риском тромбозов при проведении контролируемой антикоагулянтной профилактики сопровождалась меньшей частотой осложнений в сравнении с контрольной группой: нарушение маточно-плацентарного кровотока наблюдалось у 7,8 % против 24,3 % (p &lt; 0,05), задержка роста плода – у 3,1 % против 12,9 % (p &lt; 0,05), преэклампсия – у 6,3 % против 20,0 % (p &lt; 0,05), угроза прерывания в I триместре – у 14,1 % против 28,6 % (p &lt; 0,05), во II триместре – у 7,8% против 21,4% (p &lt; 0,05). Контролируемое применение НМГ было ассоциировано с благоприятным течением и исходом беременности. Оценка динамики показателей гемостаза на фоне терапии антикоагулянтами и антиагрегантами давала возможность обосновывать необходимость повышения дозы НМГ при развитии беременности, оценивать ее адекватность и безопасность.</p></sec><sec><title>Заключение</title><p>Заключение. Нарастание гиперкоагуляции по мере развития беременности требует контроля адекватности антикоагуляционной терапии в группах риска, особенно при многоплодной беременности после ЭКО.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гемостаз</kwd><kwd>противотромботическая терапия</kwd><kwd>низкомолекулярный гепарин</kwd><kwd>НМГ</kwd><kwd>экстракорпоральное оплодотворение</kwd><kwd>ЭКО</kwd><kwd>отягощенный акушерский анамнез</kwd><kwd>ОАА</kwd><kwd>одноплодная беременность</kwd><kwd>многоплодная беременность</kwd><kwd>беременность двойней</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemostasis</kwd><kwd>antithrombotic therapy</kwd><kwd>low molecular weight heparin</kwd><kwd>LMWH</kwd><kwd>in vitro fertilization</kwd><kwd>IVF</kwd><kwd>burdened obstetric history</kwd><kwd>ВОН</kwd><kwd>singleton pregnancy</kwd><kwd>multiple pregnancy</kwd><kwd>twin pregnancy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют об отсутствии финансовой поддержки</funding-statement><funding-statement xml:lang="en">The authors declare no funding</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mozes М., Bogokowsky Н., Antebi Е. et al.
