A two-stage observational study was conducted, consisting of sequential retrospective and prospective phases. In the retrospective phase, data from 50 patients with ACVEs that had occurred during pregnancy, in the early postpartum period, or outside gestation were analyzed; 30 clinically healthy pregnant women were included in control group. Based on the retrospective data, a prognostic model for cerebrovascular risk stratification had previously been developed; in the present study, this model was used solely as a tool to identify high-risk patients. In the prospective phase, 45 pregnant and reproductive-age women with ACVEs history or a high risk of their development, as identified by the above model, as well as 30 clinically healthy pregnant women, were examined. All patients underwent an extended clinical and hemostasiological evaluation, including assessing genetic thrombophilia, natural anticoagulant deficiencies, antiphospholipid antibodies (aPL), homocysteine levels, metalloproteinase ADAMTS-13 activity, anti-ADAMTS-13 antibodies, as well as parameters of the vWF/ADAMTS-13 axis.</p></sec><sec><title>Results</title><p>Results. In the retrospective phase, inherited and acquired forms of thrombophilia were detected significantly more often in patients with ACVEs than in control group, 84.0 % versus 6.7 % cases, respectively. Pattern of cerebrovascular events was featured with ischemic stroke diagnosed in 58.0 % patients, whereas cerebral venous thrombosis – in 42.0 % cases. In prospective group, genetically determined thrombogenic abnormalities were detected in 35.6 % patients, criterial aPLs were detected in 28.9 %, hyperhomocysteinemia – in 15.6 %, reduced ADAMTS-13 activity – in 11.1 %, anti-ADAMTS-13 antibodies – in 26.7 %, and elevated von Willebrand factor levels – in 28.9 %. Combined thrombophilia was identified in 35.6 % patients in the prospective group, suggesting the multifactorial nature of prothrombotic predisposition.</p></sec><sec><title>Conclusion</title><p>Conclusion. Latent thrombophilic conditions are frequently detected in pregnant and reproductive-age women with ACVEs history, as well as in patients at ACVE high risk, and often have a combined pattern involving both genetically determined and acquired hemostatic disorders. These findings substantiate a need for extended clinical and hemostasiological assessment in this category of patients at the stage of pregnancy planning and during pregnancy to improve risk stratification and individualize prevention of thrombotic complications.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: оценить распространенность и структуру скрытых тромбофилических состояний у беременных и женщин репродуктивного возраста с отягощенным цереброваскулярным анамнезом, а также у пациенток высокого риска развития острого нарушения мозгового кровообращения (ОНМК), выделенных с использованием ранее разработанной прогностической модели, на основании комплексного клинико-гемостазиологического анализа.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено двухэтапное обсервационное исследование с последовательно реализованными ретроспективным и проспективным этапами. На ретроспективном этапе проанализированы данные 50 пациенток с ОНМК, перенесенным во время беременности, в раннем послеродовом периоде или вне гестации; контрольную группу составили 30 клинически здоровых беременных. На основании данных ретроспективного этапа ранее была разработана прогностическая модель стратификации цереброваскулярного риска, которую в настоящем исследовании использовали только как инструмент для выделения пациенток высокого риска. На проспективном этапе обследованы 45 беременных и женщин репродуктивного возраста с ОНМК в анамнезе или высоким риском его развития, выделенных с использованием указанной модели, а также 30 клинически здоровых беременных. Всем пациенткам выполнено расширенное клинико-гемостазиологическое обследование, включавшее определение генетических форм тромбофилии, дефицитов естественных антикоагулянтов, антифосфолипидных антител (АФА), уровня гомоцистеина, активности металлопротеиназы ADAMTS-13, антител к ADAMTS-13 и показателей оси vWF/ADAMTS-13. </p></sec><sec><title>Результаты</title><p>Результаты. На ретроспективном этапе исследования у пациенток с ОНМК значимо чаще выявлялись наследственные и приобретенные формы тромбофилии по сравнению с контрольной группой – у 84,0 % против 6,7 % соответственно. В структуре цереброваскулярных событий ишемический инсульт диагностирован у 58,0 % пациенток, церебральный венозный тромбоз – у 42,0 %. В проспективной группе генетически детерминированные тромбогенные нарушения обнаружены у 35,6 %, критериальные АФА – у 28,9 %, гипергомоцистеинемия – у 15,6 %, снижение активности ADAMTS-13 – у 11,1 %, антитела к ADAMTS-13 – у 26,7 %, повышение уровня фактора фон Виллебранда – у 28,9 %. У 35,6 % пациенток проспективной группы установлена сочетанная тромбофилия, что свидетельствует о многофакторном характере протромботической предрасположенности.</p></sec><sec><title>Заключение</title><p>Заключение. У беременных и женщин репродуктивного возраста с отягощенным цереброваскулярным анамнезом, а также у пациенток высокого риска развития ОНМК скрытые тромбофилические состояния выявляются часто и нередко имеют сочетанный характер, включая как генетически детерминированные, так и приобретенные нарушения системы гемостаза. Полученные данные обосновывают необходимость расширенного клинико-гемостазиологического обследования данной категории пациенток на этапе планирования и ведения беременности для более точной стратификации риска и индивидуализации профилактики тромботических осложнений.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инсульт</kwd><kwd>острое нарушение мозгового кровообращения</kwd><kwd>беременность</kwd><kwd>тромбофилия</kwd><kwd>антифосфолипидные антитела</kwd><kwd>АФА</kwd><kwd>ADAMTS-13</kwd><kwd>гемостаз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stroke</kwd><kwd>acute cerebrovascular accident</kwd><kwd>ACVE</kwd><kwd>pregnancy</kwd><kwd>thrombophilia</kwd><kwd>antiphospholipid antibodies</kwd><kwd>aPL</kwd><kwd>ADAMTS-13</kwd><kwd>hemostasis</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">Miller E.C., Yaghi S., Boehme A.K. et al.
