Abstract:
Objective To evaluate the values of prenatal surveillances of ultrasonography in twin pregnancies with amniotic fluid discordance. Methods Two hundred and seventy cases of diamniotic twins were included. Both postnatal outcomes and prenatal amniotic fluid discordant variations were analyzed,and the incidences of amniotic fluid discordance were compared between the monochorionic-diamniotic(MCDA)and dichorionic-diamniotic (DCDA) gruop. Results Twenty four cases of twins with amniotic fluid discordance were found in the study. The incidence of amniotic fluid discordance in MCDA group was much higher than that in DCDA group (28.9% vs 5.6%, P ＜0. 001 ) ,and 24 cases of twin-to-twin transfusion syndrome (TTTS) were diagnosed in the former group and none were found in the latter group. Downward tendency of amniotic fluid discordance was shown in non-TTTS cases of MCDA group. Compared with TTTS cases, the postnatal outcomes of non-TTTS cases with amniotic fluid discordance were much better in MCDA group ( P ＜0.001 ). Conclusions TTTS and MCDA twins with amniotic fluid discordance may overlap each other in the early stage. Serial surveillances of ultrasonography are necessary for prenatal differentiating twin pregnancies complicated by amniotic fluid discordance,and providing strong support to clinical treament.
