EP19.16: Prediction of fetal macrosomia using two‐dimensional and three‐dimensional ultrasound.

The projection of the EFW at the time of delivery was performed by using Yudkin's chart percentiles and the gestation-adjusted projection (GAP) method. A significant correlation between the EFW percentile and the birthweight percentile was found both for the 2D-US-EFW centile (0.654, r SP 2 sp 0.430, p <0.001) and the 3D-US-EFW centile (0.678, r SP 2 sp 0.460, p <0.001) as well as for the 2D-US-EFW-GAP and the 3D-US-EFW-GAP (0.600, r SP 2 sp 0.360, p <0.001 and 0.629, r SP 2 sp 0.396, p <0.001, respectively). Similarly, a non-significant difference in the accuracy of the prediction of birthweight > 4000 grams (AUC 0.788, 95% CI 0.716-0.859 for 2D-US-EFW vs AUC 0.802, 95% CI 0.723-0.880 for 3D-US-EFW, p 0.72) and > 4500 grams (0.828, 95% IC 0.720-0.936 for 2D-US-EFW vs 0.858, 95% IC 0.759-0.956 for 3D-US-EFW, p 0.71) with the GAP method could be demonstrated.
