In twin-twin transfusion syndrome (TTTS) and twin anemia-polycythemia sequence (TAPS) inter-twin blood transfusion is unbalanced, resulting in high mortality rates if left untreated. This guidance is for the management of these infants in order to prevent further complications.
3. Though the condition has been known . This disorder may result from postmaturity, diabetes in the mother, twin-to-twin transfusions, in which blood flows from one fetus to the other, or a low oxygen level in the fetus's blood.
