Abstract: OBJECTIVE: To identify predictors of twin-to-twin transfusion syndrome (TTTS) and selective intra-uterine growth restriction (sIUGR) in monochorionic diamniotic twin pregnancies with moderate amniotic fluid discordance (mAFD). METHODS: Monochorionic twins with mAFD (n = 45; gestational age range 15-29 weeks) were assessed for severity of fluid discordance, fetal growth discordance and fetal cardiac dysfunction and followed longitudinally. A prediction algorithm was constructed for TTTS and sIUGR and validated in an unrelated cohort (n = 52). RESULTS: Cardiac dysfunction could not predict TTTS nor sIUGR. Twins with a fluid discordance >/= 3.1cm below 20 weeks of gestation had a risk of TTTS of 85.7%. Sensitivity for TTTS was nevertheless only 55%. Intertwin weight discordance >/= 25% had 63% sensitivity and 76% specificity for sIUGR without TTTS. CONCLUSION: Outcome of monochorionic diamniotic twins with mAFD remains unpredictable yet high and low risk subgroups for TTTS can be identified based on severity of fluid discordance and gestational age.
