Monochorionic twin pregnancies are associated with a range of complications, including:
- Twin-to-Twin Transfusion Syndrome (TTTS): This occurs when blood flows unequally between the twins through shared blood vessels in the placenta. One twin receives too much blood (recipient twin), while the other receives too little (donor twin). This can lead to serious health issues for both twins. - Selective Intrauterine Growth Restriction (sIUGR): One twin may experience restricted growth due to unequal sharing of the placenta. - Twin Anemia-Polycythemia Sequence (TAPS): A form of TTTS where one twin becomes anemic and the other polycythemic without the classical signs of TTTS. - Congenital Anomalies: The risk of congenital anomalies is higher in monochorionic twins compared to dichorionic twins. - Preterm Birth: Monochorionic twins often require early delivery due to complications, increasing the risk of preterm birth and associated neonatal complications.
