A total of 132 women with the aggravated obstetrical history were examined: Group 1 – 42 patients with the history of placenta previa; Group 2 – 60 pregnant women diagnosed with placenta previa in the current pregnancy; Group 3 – 30 pregnant women with the history of placenta previa and the same abnormality in the current pregnancy. The control group included 120 women with no abnormalities in their obstetric history and with normal location of placenta during the current pregnancy. All patients were assessed for the antiphospholipid antibodies using an enzyme immunoassay. The presence of genetic forms of thrombophilia was tested (with polymerase chain reaction and three pairs of oligonucleotide primers) for the following mutations: the C677T mutation in the 5,10-methylenetetrafolate reductase gene, the prothrombin mutation in the G20210A gene, mutations in the Leiden factor V gene, polymorphism 675 4G/5G in the gene of the inhibitor of plasminogen activator type 1, polymorphism 455G/A in the fibrinogen gene.</p></sec><sec><title>Results</title><p>Results. The thrombophilia spectrum in patients with placenta previa during the current pregnancy and those with abnormal placenta location in the past did not significantly differ from each other. However, in patients with both abnormal placental locations in the past and the present pregnancy, there was a greater occurrence of both genetic and acquired forms of thrombophilia. In the control group, much fewer cases of either genetic or acquired thrombophilia were found.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained results suggest a connection between thrombophilia and the abnormal location of placenta. Women with the abnormal placenta location either in the past or during the current pregnancy should be routinely tested for the genetic markers of thrombophilia and for hemostasis abnormalities.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель исследования</title><p>Цель исследования: установление патогенетической связи между патологическим расположением плаценты и наличием генетических и приобретенных форм тромбофилии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 132 пациентки с отягощенным акушерским анамнезом: 1 группа – 42 пациентки с предлежанием плаценты в анамнезе; 2 группа – 60 беременных с выявленным предлежанием плаценты во время настоящей беременности; 3 группа – 30 беременных с предлежанием плаценты в анамнезе и во время настоящей беременности. Контрольную группу составили 120 женщин без отягощенного акушерского анамнеза и с нормальным расположением плаценты во время настоящей беременности. Всем пациенткам проводили определение уровня антифосфолипидных антител методом иммуноферментного анализа, исследование генетических форм тромбофилии путем проведения полимеразной цепной реакции с использованием трех пар олигонуклеотидных праймеров: мутации C677T в гене 5,10-метилентетрафолатредуктазы, мутации протромбина в гене G20210A, мутации в гене фактора V Leiden, полиморфизма 675 4G/5G в гене ингибитора активатора плазминогена 1 типа, полиморфизма 455G/A в гене фибриногена.</p></sec><sec><title>Результаты</title><p>Результаты. Спектр тромбофилии у пациенток с предлежанием плаценты во время настоящей беременности и аномалией локализации плаценты в анамнезе не отличался в значительной степени; однако в группе пациенток, у которых аномальное расположение плаценты было и в анамнезе и во время настоящей беременности, отмечалось большее распространение как генетических, так и приобретенных форм тромбофилии. В контрольной группе отмечено существенно более редкое распространение как генетических, так и приобретенных форм тромбофилии.</p></sec><sec><title>Заключение</title><p>Заключение. На основании полученных данных можно высказать предположение о наличии связи между тромбофилией и аномалиями локализации плаценты. Обследование на наличие генетических форм тромбофилии и оценка параметров гемостаза должны быть обязательными компонентами обследования женщин с аномалиями расположения плаценты в анамнезе и во время текущей беременности.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аномалии локализации плаценты</kwd><kwd>тромбофилия</kwd><kwd>нарушения гемостаза</kwd><kwd>профилактика осложнений беременности</kwd><kwd>низкомолекулярный гепарин</kwd><kwd>ведение беременности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>abnormal placental location</kwd><kwd>thrombophilia</kwd><kwd>hemostasis disorders</kwd><kwd>prevention of pregnancy complications</kwd><kwd>low molecular weight heparin</kwd><kwd>pregnancy management</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">Медянникова И.В.
