Abstract Objective The aim of this study is to explore the effectiveness of cervical cerclage in order to delay the delivery interval after delivery of the first fetus in dichorionic twin pregnancies. Study Design: Records of 11 twin pregnancies where delayed delivery was experienced for retained fetus(es), were collected retrospectively. Cases with cervical cerclage placed after the first delivery were evaluated as the cerclage group and cases without cerclage placement were evaluated as the non-cerclage group. Results The median duration of the delay 25.4 ± 8.1days (range, 4–50) in the cerclage group and 7.7 ± 2.0 days(range, 3–17) in the non-cerclage group (P = 0.045). Average gain birthweight of the second fetus in the cerclage group was 408.0 ± 160.2 g and 93.3 ± 25.5g in the non-cerclagegroup(P = 0.061). But other parameters were not different between the two groups. Conclusions Cervical cerclage after the first delivery is associated with a longer inter-delivery interval without increasing the risk of intrauterine infection.

AbstractObjective. The aim was to determine the chorionic and amniotic types in multifetal pregnancies with transvaginal ultrasonography at very early stage of gestation.Study design. Twenty-one spontaneous multifetal pregnancies were scanned transvaginally before 8 weeks' gestation (four of them from 4th week). The chorionic and amniotic type was determined ultrasonographically. All twin gestations had postpartum pathologic evaluation of the placenta and histologic determination of the chorionic and amniotic type.Results. Ultrasonographic evaluation of the 21 pregnancies demonstrated 20 twin and 1 triplet gestation. Four of the twin pregnancies were monochorionic-diamniotic. Triplet was monochorionic-triamniotic (spontaneously aborted in 8th week of gestation). In all 20 twin pregnancies, transvaginal ultrasonography correctly predicted the chorionic and amniotic type before 8 weeks of gestation.Conclusion. Transvaginal ultrasonography allows a reliable, simple and rapid determination; the dichorionic twin pregnancy in 4 weeks, monochorionic in 5 weeks, and differentiation of mono-or diamniotic in 7 weeks of gestation.
