In monochorionic (identical) twin pregnancies, two fetuses share a placenta. Selective intrauterine growth restriction (sIUGR) can occur if the placenta is not evenly apportioned between the twins. Because the placenta provides nourishment necessary for the growth and development of the twins, if there is an imbalance present, one twin may become malnourished. In severe cases of sIUGR, the fetuses share a circulatory system. Abnormal blood flow through the umbilical artery may endanger the survival of the restricted growth twin. Treatment options for sIUGR include surgically removing linked blood vessels and separation of the circulatory system.
