1131: Growth velocity in monochorionic and dichorionic twins - results of the multicenter ESPRiT Twin Study

The NICHD Fetal Growth Study quantifies mean weekly singleton fetal weight gain after 30 weeks gestation at 200g. We sought to determine the comparable growth velocity pattern in monochorionic and dichorionic twins. Viable twin pregnancies without congenital anomalies or twin-twin transfusion syndrome were analyzed. Fetal biometry was measured every 2 weeks from 16 weeks gestational age for monochorionic and 20 weeks for dichorionic pregnancy....
