A detailed analysis of the literature and clinical case of pregnancy management in a patient with AT-III deficiency, pulmonary embolism and habitual history of miscarriage has been performed and presented. Patients with AT-III deficiency are at high risk for developing thrombotic and obstetric complications even despite using therapeutic doses of anticoagulants. Indications for use and modes of administration of AT-III concentrate have not been currently defined clearly. Monitoring therapy with low molecular weight heparin is largely complicated because a test for determining anti-Xa activity is AT-III-dependent. In addition to standard methods for controlling antithrombotic therapy, we used tests characterizing the dynamic blood clot parameters: thromboelastography and thrombin generation test. The peak risk resulting in both thrombotic and hemorrhagic complications in such patients occurs during period of labor and the postpartum period, when a change in the regimen of anticoagulant therapy is required with its temporary withdrawal and additional administration of AT-III concentrate.</p></abstract><trans-abstract xml:lang="ru"><p>Работа посвящена проблеме ведения беременности при наиболее тромбогенной генетической тромбофилии - дефиците антитромбина III (AT-III). Проведен детальный анализ литературы и представлен разбор собственного клинического случая ведения беременности у пациентки с дефицитом AT-III, тромбоэмболией легочной артерии и привычным невынашиванием беременности в анамнезе. Пациентки с дефицитом AT-III относятся к группе высокого риска по развитию тромботических и акушерских осложнений, даже несмотря на терапевтические дозы антикоагулянтов. Показания к применению и режимы введения концентрата AT-III в настоящее время четко не определены. Контроль терапии низкомолекулярным гепарином в значительной степени затруднен, так как тест на определение анти-Ха активности является AT-III-зависимым. Помимо стандартных методов контроля антитромботической терапии, мы использовали тесты, характеризующие динамические параметры сгустка: тромбоэластограмму, тест генерации тромбина. Наибольший риск с точки зрения как тромботических, так и геморрагических осложнений у таких больных представляет период родов и послеродовый период, когда требуется изменение режима антикоагулянтной терапии с временной ее отменой и дополнительное введение концентрата AT-III.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дефицит антитромбина III</kwd><kwd>беременность</kwd><kwd>низкомолекулярный гепарин</kwd><kwd>концентрат антитромбина III</kwd><kwd>ривароксабан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antithrombin III deficiency</kwd><kwd>pregnancy</kwd><kwd>low molecular weight heparin</kwd><kwd>antithrombin III concentrate</kwd><kwd>rivaroxaban</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">Di Minno M.N., Ambrosino P., Ageno W. et al.
