Embryonic growth discordance and early fetal loss: the STORK multiple pregnancy cohort and systematic review.
STUDY QUESTION Is there an association between discordance in embryonic growth and fetal loss at the time of the 11-14-week scan in twin pregnancies? SUMMARY ANSWER Regardless of the chorionicity, crown rump length (CRL) discordance at 7(+0)-9(+6) weeks is predictive of subsequent single fetal demise in the first trimester. WHAT IS KNOWN ALREADY Previous small studies have reported a variab...
متن کاملCrown-rump length discordance and adverse perinatal outcome in twins: analysis of the Southwest Thames Obstetric Research Collaborative (STORK) multiple pregnancy cohort.
OBJECTIVE Evidence for the role of first-trimester ultrasound in predicting outcome in twin pregnancies is conflicting. The aim of this study was to determine the association between crown-rump length (CRL) discordance and adverse perinatal outcome in twin pregnancies. METHODS This was a retrospective study of all twin pregnancies of known chorionicity from a large regional cohort over a 10-y...
متن کاملWeight discordance and perinatal mortality in twins: analysis of the Southwest Thames Obstetric Research Collaborative (STORK) multiple pregnancy cohort.
OBJECTIVES The degree of actual intertwin birth weight (BW) or ultrasound estimated fetal weight (EFW) discordance that justifies elective delivery is yet to be established. The main aim of this study was to ascertain the performance of BW and ultrasound EFW discordance in the prediction of perinatal loss in twin pregnancies. METHODS This was a retrospective study of all twin pregnancy births...

The nested nature of the sets of measurements obtained for each fetus and pairs of twins within each pregnancy means that the analysis of fetal growth in twin pregnancies is particularly suited to the application of multilevel modelling. The term ‘multilevel modelling’ describes a mixed effects approach in which sets of measurements within each individual and/or individuals within groups form a...
متن کاملPatterns of Second- and Third-Trimester Growth and Discordance in Twin Pregnancy: Analysis of the Southwest Thames Obstetric Research Collaborative (STORK) Multiple Pregnancy Cohort.
INTRODUCTION This study investigates patterns of intertwin size discordance in dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twin pregnancies. MATERIAL AND METHODS Ultrasound measurements of twin pregnancies, from 14 weeks to term, were collected by 9 hospitals over a 10-year period. This analysis considers the modelled and observed levels of discordance in abdominal circu...
