EP04.01: First trimester prediction of ventriculomegaly.

The ratio of choroid plexus to lateral ventricle area (PAVAR), choroid plexus to lateral ventricle length (PLVLR), choroid plexus to lateral ventricle diameter (PDVDR), choroid plexus area to biparietal diameter (PA/BPD) and choroid plexus area to head circumference (PA/HC) were measured at 11-13 + 6 weeks. Conclusions First trimester prediction of ventriculomegaly using fetal choroid plexus to ventricle ratios appears promising. PA/BPD ratio (AUC 0.76, 95% CI 0.63-0.89) and PA/HC ratio (AUC 0.75, 95% CI 0.63-0.87) had modest predictive capabilities, which were significantly lower compared to PAVAR (P = 0.003 and P = 0.001, respectively).
