This pathology rate tends to increase also due to higher number of pregnancies achieved via in vitro fertilization (IVF). In this regard, we decided to find out the key risk factors for developing this pathology, identify new international data on placentation abnormalities, ART impact on this disease, since ART have been increasingly used to achieve pregnancy in women, both in Russia and abroad. Recent studies have proven the unique morphological structure of the placental hematopoietic barrier in post-IVF women as well as an increased incidence of placentation abnormalities, placenta accreta and premature abruption in comparison with spontaneous pregnancy.</p></abstract><trans-abstract xml:lang="ru"><p>Аномалии плацентации после применения вспомогательных репродуктивных технологий (ВРТ) являются актуальной проблемой в акушерстве во всем мире в связи с осложнениями, связанными с патологией: кровотечение во время беременности, послеродовое кровотечение, увеличение числа кесаревых сечений, перинатальная и материнская заболеваемость и смертность. Патология имеет тенденцию к увеличению, в том числе и в связи с ростом количества беременностей, наступивших при помощи экстракорпорального оплодотворения (ЭКО). В связи с этим нами было решено выяснить ключевые факторы риска патологии, найти новые мировые данные об аномалиях плацентации, влияния ВРТ на данную акушерскую нозологию в связи с увеличивающимся их использованием для наступления беременности у женщин как в России, так и в мире. В последних исследованиях доказано различное морфологическое строение плацентарного кроветворного барьера у женщин после ЭКО, а также увеличенная частота аномалий плацентации, врастания плаценты и ее преждевременной отслойки в сравнении с самостоятельно наступившей беременностью.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аномалии плацентации</kwd><kwd>экстракорпоральное оплодотворение</kwd><kwd>ЭКО</kwd><kwd>вспомогательные репродуктивные технологии</kwd><kwd>ВРТ</kwd><kwd>врастание плаценты</kwd><kwd>отслойка плаценты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>placentation abnormalities</kwd><kwd>in vitro fertilization</kwd><kwd>IVF</kwd><kwd>assisted reproductive technologies</kwd><kwd>ART</kwd><kwd>placenta accreta</kwd><kwd>placental abruption</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">Доброхотова Ю.Э., Боровкова Е.И., Куликов И.А. и др.
