352: Ultrasound prediction of growth abnormalities in fetuses with gastroschisis


      To determine if 1) mean abdominal circumference (AC) of fetuses with gastroschisis are smaller from published normative values and whether 2) diagnosis of AC < 5th percentile is supported by postnatal diagnosis of small for gestational age (SGA).

      Study Design

      This was a retrospective review of pregnancies complicated with gastroschisis between 2000 and 2008. AC was classified as < 5th percentile or > 5th percentile on the final sonogram prior to delivery. Intrauterine growth restriction (IUGR) was defined as EFW < 10th percentile. SGA was defined as neonatal birthweight < 10th percentile.


      Three hundred sixty eight ultrasound observations, performed in 74 fetuses with gastroschisis, were used for analysis. Mean AC of fetuses with gastroschisis were between the 5th and 50th percentile for gestational age. Of the 30 (40.5%) patients with AC measurements < 5th, 15 (50%) were SGA at delivery. Eleven of the 74 fetuses (15%) were classified as IUGR and all were SGA postnatally.
