Overall neonatal survival rate was 64.9% (135\/208) and 77.9% of pregnancies (81\/104) had at least one baby alive. For the recipient twin, the preoperative predictors of neonatal survival were umbilical artery (UA) pulsatility index (PI), cerebro\u2010placental PI ratio, UA end diastolic flow (EDF), ductus venosus a\u2010wave, right ventricular myocardial performance index (RV\u2010MPI) and CHOP score.
