The chorionicity-based evaluation of the perinatal risk in twin pregnancies after assisted reproductive technology (ART) is lacking. A retrospective review was performed of all twin pregnancies monitored prenatally and delivered at our hospital between 2010 and 2014. Chorionicity was diagnosed by ultrasound examination at first trimester and confirmed by postnatal pathology. Pregnancy and perinatal outcomes were prospectively recorded. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were calculated in a logistic regression model...

OBJECTIVES: The overwhelming numbers of twins following assisted reproductive technology (ART) are dichorionic twins, but monochorionic twins account for around 0.9% of post ART pregnancies. The data for post ART-monochorionic pregnancy outcomes are scarce due to the rarity of this condition. Hence, we evaluated the obstetric outcomes of monochorionic and dichorionic pregnancies conceived on ART. SETTINGS: University teaching hospital. STUDY DESIGN: A case-control study of monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) pregnancies conceived following ART treatment...

OBJECTIVE: To investigate the relation between first-trimester fetal growth discrepancy, as assessed by crown-rump length (CRL) at 11+0 to 13+6 weeks of gestation, and subsequent development of preeclampsia (PE) in dichorionic diamniotic (DCDA) twin pregnancies. The association between inter-twin CRL and birth weight (BW) discrepancy was also investigated. METHODS: This was a retrospective, case-control study of DCDA twin pregnancies. Inter-twin CRL discrepancy was calculated as 100×(larger CRL-smaller CRL)/larger CRL...

Advanced maternal age may be associated with adverse maternal and perinatal outcomes in singleton pregnancies. It is unclear whether a similar association exists for dichorionic twins. This objective of this study was to ascertain whether advanced maternal age was associated with increased perinatal morbidity and mortality in a 15 year retrospective review of dichorionic diamniotic (DCDA) twins delivered at Queen Charlotte's and Chelsea Hospital, a tertiary referral center in London, UK, between 1994 and 2008...

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 versus 3.5%, P < 0.001), the umbilical artery pH of <7.2 was similar (20 versus 13%, P > 0.05). Admission to neonatal intensive care unit (NICU) and neonatal mortality were also similar in both groups...
