Одним из самых распространённых и тяжелых осложнений монохориальной беременности является синдром фето-фетальной трансфузии (СФФТ). Частота встречаемости синдрома трансфузии у монохориальных диамниотических двоен составляет от 10 до 15%.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Проанализировать ангиоархитектонику плаценты при синдроме фето-фетальной трансфузии (СФФТ), определить ее особенности при благоприятном и неблагоприятном исходе после лазерной коагуляции плацентарных анастомозов (ЛКПА).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Сплошное проспективное, когортное, сравнительное исследование. Обследовано 90 беременных женщин с монохориальными диамниотическими двойнями: у 60 человек (основная группа) беременность осложнилась СФФТ, у 30 пациенток (группа сравнения) беременность характеризовалась нормальным течением; их новорожденные и последы. Основная группа была разделена на 2 подгруппы в зависимости от исхода ЛКПА с целью коррекции СФФТ: подгруппа 1 — благоприятный исход (n=50), подгруппа 2 — неблагоприятный исход (n=10).</p></sec><sec><title>Результаты</title><p>Результаты. Ангиоархитектоника плаценты при СФФТ при благоприятном исходе ЛКПА характеризуется наличием крупных артерио-венозных плацентарных анастомозов в совокупности с «центрально-центральным» и «центрально-краевым» вариантами прикрепления пуповин. Большее количество анастомозов регистрируется у монохориальных двоен с СФФТ и сосудистые рисунки с двумя и более артерио-венозными анастомозами («Тип В» и «Тип D»), в нашем исследовании данные виды ангиоархитектоники встречались чаще при неблагоприятном исходе лазерной коагуляции плацентарных анастомозов (ОШ=5,23 (95% ДИ 2,13; 12,8); p&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Ангиоархитектоника плаценты при синдроме фето-фетальной трансфузии при благоприятном исходе лазерной коагуляции плацентарных анастомозов характеризуется наличием крупных артерио-венозных плацентарных анастомозов в совокупности с «центрально-центральным» и «центрально-краевым» вариантами впадения пуповин. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. One of the most common and severe complications of monochorionic pregnancy is feto-fetal transfusion syndrome (FFTS). The incidence of transfusion syndrome in monochorial diamniotic twins ranges from 10 to 15%.</p></sec><sec><title>Objective</title><p>Objective. To analyze the angioarchitecture of the placenta in FFTS, to determine its features with a favorable and unfavorable outcome after laser coagulation of placental anastomoses (LPCA).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Continuous prospective, cohort, comparative study 90 pregnant women with monochorionic diamniotic twins were examined: in 60 people (the main group) the pregnancy was complicated by FFTS, in 30 patients (the comparison group) the pregnancy was characterized by a normal course; their newborns and afterbirths. The main group was divided into 2 subgroups depending on the outcome of LCPA in order to correct FFTS: subgroup 1 — favorable outcome (n=50), subgroup 2 — unfavorable outcome (n=10). </p></sec><sec><title>Result</title><p>Result. The angioarchitecture of the placenta in FFTS with a favorable outcome of LCPA is characterized by the presence of large arteriovenous placental anastomoses in combination with “central-central” and “central-marginal” variants of umbilical cord attachment. A larger number of anastomoses is recorded in monochorionic twins with FFTS and vascular patterns with two or more arteriovenous anastomoses (“Type B” and “Type D”), in our study they were more common with an unfavorable outcome of laser coagulation of placental anastomoses (OR = 5.23 (95%CI 2.13;12.8);p&lt;0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Angioarchitectonics of the placenta in feto-fetal transfusion syndrome with a favorable outcome of laser coagulation of placental anastomoses is characterized by the presence of large arteriovenous placental anastomoses in combination with “central-central” and “central-marginal” variants of umbilical cord confluence.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром фето-фетальной трансфузии</kwd><kwd>монохориальная диамниотическая двойня</kwd><kwd>хирургическая коррекция синдрома фето-фетальной трансфузии</kwd><kwd>перинатальные исходы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>twin-to-twin transfusion syndrome</kwd><kwd>monochorionic diamniotic twins</kwd><kwd>surgical correction of twin-to-twin transfusion</kwd><kwd>perinatal outcomes</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">Сергеева А.В., Каткова Н.Ю., Бодрикова О.И., Ковалише на О.В., Безрукова И.М., Покусаева К.Б.
