Objective: To examine the correlation between measurements of crown rump length (CRL), nuchal translucency (NT), and birth weight in dichorionic (DC) and monochorionic (MC) twin pregnancies. Methods: A retrospective analysis was performed on all twin term pregnancies delivered between 2001 and 2007 at the McGill University Health Center. Data collected included maternal age, CRL and NT measurement, results of glucose challenge test, birth weight and length, gestational age at delivery, and fetal gender. Results: The study population comprised 792 fetuses: 94 MC/DA and 698 DC/DA. Maternal age, gestational age at delivery, birth weight, and birth length were all significantly higher for the DC group. Male fetuses had significantly higher NT and higher birth weight than female fetuses. Discordance in CRL was found to correlate with discordance in birth weight in the entire study population (Pth percentile (>12%) predicted 14/40 pregnancies with birth weight discordance above the 90th percentile (>24%) [Pth percentile (>16%) predicted 5/21 pregnancies with birth weight discordance above the 95th percentile (>30%) [P Conclusion: In twin pregnancies, CRL discordance in first trimester can predict discordance of more than 25% in neonatal birth weight.
