The Pre-Twin Screen Consortium proposal for fetal structural anomalies evaluation across all three trimesters in twin pregnancies.

ABSTRACT:

Purpose

In singleton pregnancies, routine ultrasound examinations in each trimester improves the diagnosis of fetal abnormalities and their management. In this study, we examine twin pregnancies and report on the detection of fetal anomalies in each trimester and postnatally as well as on the type of anomalies and their prevalence.

Methods

This prospective multicenter study enrolled pregnant women with dichorionic (DC) and monochorionic diamniotic (MCDA) twins at gestational weeks (GA) 11 + 0 to 13 + 6 in six medical centers (two in Germany, and one each in Spain, Canada, Italy, and Israel). Pregnancies were dated by the crown-rump length of the larger twin. Detailed scans were performed according to the guidelines of the International Society of Ultrasound in Obstetrics and
