The role of ultrasound examination in the first trimester and at 16 weeks' gestation to predict fetal complications in monochorionic diamniotic twin pregnancies

Of the MCDA twin pregnancies classified as high risk on the combined first trimester and 16 weeks assessment (n = 41), 73% had a complicated fetal outcome with a survival rate of only 69%. In contrast, of the pregnancies classified as low risk (n = 154), 86% had an uneventful fetal outcome with a survival rate of 95%.
