Monochorionic Diamniotic Twin Pregnancies: Natural History and Risk Stratification

摘要: About 30% of monochorionic twin pregnancies are complicated by twin-to-twin transfusion syndrome (TTTS), isolated discordant growth, anemia-polycythemia sequence, congenital defects or intrauterine demise. 15% will be eligible for invasive fetal therapy, either fetoscopic laser treatment TTTS ultrasound-guided umbilical cord coagulation a severe defect in one growth with imminent demise the growth-restricted twin. Ultrasound examination first and early second trimester can differentiate twins at high risk adverse outcome from those likely to uneventful, which may useful patient counselling planning care.
