June 2005 | Volume 2 | Issue 6 | e195 | e198 As mothers get older and assisted conception becomes more common in developed countries, the incidence of multiple births—primarily of nonidentical siblings, but also of identical ones—has dramatically increased. Multiple pregnancies are high-risk pregnancies, with preterm delivery and monochorionicity (shared placenta) the major problems. Consequent...

OBJECTIVE Discordance in nuchal translucency measurements in monochorionic diamniotic twin pregnancies was assessed as predictor of Twin-to-Twin Transfusion Syndrome. STUDY DESIGN A total of 61 monochorionic diamniotic twins were enrolled. Nuchal translucency (NT) and crown-rump-length (CRL) discordance was calculated as the percentage of delta NT and CRL (absolute difference NT/CRL fetus 1 a...

Umbilical cord entanglement has been reported to occur in monoamniotic twins. However, it can occur in diamnionic twins due to rupture of the intertwin-dividing membrane, and is a cause for concern. A 31-year-old nullipara visited our hospital at 28+3 weeks gestation. A monochorionic diamniotic twin gestation was diagnosed ultrasonographically by visualizing a thin intertwin-dividing membrane a...

We examined the prevalence of specific perinatal complications of monochorionic-diamniotic twin pregnancies in cases without any abnormal findings until the second trimester of pregnancy. This was a retrospective cohort study performed at a tertiary perinatal center in Tokyo, Japan. There were 88 cases of uncomplicated monochorionic-diamniotic twin pregnancies at 28 weeks of gestation. In five ...

The outcomes of 60 sets of monochorionic diamniotic (MCDA) twins were compared with 218 sets of dichorionic diamniotic (DCDA) twins. The caesarean section rates for MCDA were similar to those for DCDA twins (56.6 versus 53.6%, P > 0.1). Although the number of babies with 5-minute Apgar score of <7 was significantly higher for vaginally delivered MCDA twins compared with that of DCDA twins (12 v...

Monochorionic twins are usually monozygotic and thus usually have the same sex. A case of monochorionic diamniotic twins following IVF/ICSI and laser treatment of the zona pellucida ("assisted hatching") is presented in which partial embryo amalgamation appears to have occurred. Discordant sex between the twins was suspected on detailed antenatal ultrasound at 13 + 3 weeks gestation and was con...

Background: Monochorionic twin gestations are at increased risk of a variety of pregnancy complications which can be minimized by early antepartum diagnosis and management. This study is to assess the influence of chorionicity in twin pregnancies on perinatal outcome. Materials and Methods: A prospective study was conducted at, Institute of maternal and child health Calicut over a period of one...

congenital varicella syndrome encompasses a broad spectrum of malformations present in children of mothers who developed chickenpox during the fi rst 20 weeks of gestation. we report a case of a monochorionic diamniotic twin pregnancy, with maternal exposure to chickenpox during the thirteenth week of gestation, which produced one symptomatic and one healthy child.
