ФФТС V стадии (наступила внутриутробная гибель плода с многоводием), при исследовании у живого плода выявлены признаки анемии тяжелой степени (максимальная систолическая скорость кровотока в средней мозговой артерии (МССК СМА) – 1,77 МоМ – множитель медианы), водянка, нулевой диастолический кровоток в артерии пуповины. На первом этапе была выполнена амниоредукция в объеме 2500 мл, затем трансфузия 20 мл отмытых эритроцитов. Гемоглобин плода нормализован (45–134 г/л, 0,39–1,17 МоМ), гемодинамика стабилизирована. В течение 2 сут у плода сохранялась анурия, и диагностировано геморрагическое поражение центральной нервной системы. Беременность прервана по медицинским показаниям. Все нарушения подтверждены морфологически, выявлена дискордантность плодов по кариотипу. Клиническое наблюдение свидетельствует, что допплерометрия с оценкой МССК СМА плода позволяет определить анемию плода при ФФТС, демонстрирует большие компенсаторные возможности сердечно-сосудистой системы плода, что позволяет рассчитывать на успех лечения тяжелой анемии даже при критических состояниях кровотока, и показывает важность полноценного морфологического и генетического исследования при неблагоприятном исходе беременности для понимания и правильной оценки выбранной акушерской тактики.</p></abstract><trans-abstract xml:lang="en"><p>Twin-to-twin transfusion syndrome (TTTS) Stage V is a severe complication of monochorionic multiple pregnancy associated with a high risk of severe anemia in the surviving co-twing, cerebral hemorrhage or ischemic stroke and fast intrauterine fetal death of this co-twin.</p><p>A 27-year-old pregnant patient D., admitted with the diagnosis: second pregnancy, 21 weeks 1 day, TTTS Stage V (intrauterine death of the hydropic donor twin), underwent ultrasound evaluation of the surviving fetus, which demonstrated signs of severe anemia (peak systolic velocity in the middle cerebral artery [MCA-PSV] 1.77 MoM), hydrops, and absent end-diastolic flow in the umbilical artery). The first step was amnioreduction of 2500 ml, followed by fetal transfusion of 20 ml.. Fetal hemoglobin levels were  normalized (45–134 g/L, 0.39–1.17 MoM), and hemodynamics  was stabilized. Despite this, the fetus developed persistent anuria for 48 hours, and hemorrhagic central nervous system injury was diagnosed. The pregnancy was terminated for medical reasons. All abnormalities were confirmed morphologically, and karyotypic discordance between the twins was identified.</p><p>The clinical case demonstrates that Doppler assessment of fetal MCA-PSV allows reliable detection of anemia in TTTS, highlights the significant compensatory capacity of the fetal cardiovascular system that may permit successful treatment of severe anemia even under critical hemodynamic conditions, and emphasizes the importance of comprehensive morphological and genetic evaluation following an adverse pregnancy outcome to ensure correct interpretation of obstetric management decisions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>монохориальная двойня</kwd><kwd>анемия плода</kwd><kwd>внутриутробное переливание крови плоду</kwd><kwd>трисомия 16</kwd><kwd>пренатальная диагностика</kwd><kwd>ультразвуковая диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>monochorionic twins</kwd><kwd>single intrauterine fetal death</kwd><kwd>fetal anemia</kwd><kwd>cerebral injury</kwd><kwd>trisomy 16</kwd><kwd>prenatal diagnosis</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">Костюков К.В., Гладкова К.А., Сакало В.А., Шмаков Р.Г., Тетруашвили Н.К., Гус А.И.
