Ultrasonic growth pattern of fetuses with chromosomal aberrations

A retrospective analysis of the ultrasonic growth patterns of two 13-15 trisomies, two 18-trisomies and eight 21-trisomies is presented. The patterns were examined by serial cephalometry, abdominometry and head-to-abdomen circumference measurements. Early and symmetric growth retardation was revealed by ultrasonography and later confirmed by postnatal pediatric examinations in the 13-15 trisomies and 18-trisomies. In the 21-trisomies, fetal growth was normal.
