Abstract

Twins achieved through in-vitro fertilisation often undergo a viability ultrasound at 6-9 weeks of gestation. The presence of inter-twin crown-rump length discordance at this stage is not an uncommon finding; however the clinical significance of this is unknown. We analyzed 218 dichorionic twin pregnancies, producing two live fetuses > 24 weeks gestation, to determine whether inter-twin discordance (> or = 85th centile) in the mid-first trimester was associated with birthweight discordance (> 20%), or small for gestational age (< 10th centile). The incidence of birthweight discordance and small for gestational age infants were determined, with no increased risk found for the discordant popul..
