Adverse perinatal outcomes in twins: comparison of intertwin fetal size discordance vs singleton and twin fetal growth charts.

ABSTRACT:

Objective

To compare the predictive performance of intertwin estimated fetal weight (EFW) discordance and EFW centile calculated according to either the Fetal Medicine Foundation (FMF) singleton or twin-specific fetal growth charts for adverse perinatal outcome in dichorionic and monochorionic twin pregnancies.

Methods

This was a retrospective multicenter cohort study of twin pregnancies managed between January 2013 and December 2023 at three tertiary fetal medicine centers in the UK, Italy and Belgium. Twin pregnancies in which an obstetric ultrasound exam was performed to obtain fetal biometry within 2 weeks before live birth or diagnosis of intrauterine fetal demise of one or both twins were included. Cases with anastomotic complications were excluded. The primary outcome
