Abstract

OBJECTIVE

The objective of the study was to compare the 3-dimensional power Doppler (3DPD) of the uteroplacental circulation space in the first trimester between women who subsequently deliver growth-restricted vs normally grown neonates.

STUDY DESIGN

This was a prospective observational study of singleton pregnancies at 11-14 weeks' gestation. The 3DPD indices, vascularization index, flow index, and vascularization flow index were determined on a uteroplacental circulation space sphere biopsy with the virtual organ computer-aided analysis program. Growth restriction was defined as a birthweight less than the 10th percentile for gestational age and was evaluated using both population-based and customized birth curves.

RESULTS

Five hundred seventy-seven women were enrolled. Five hundred twenty-six were eligible for analysis using population centiles, and 497 were available for evaluation using customized centiles. There was no difference in the first-trimester 3DPD indices between patients with growth-restricted and normally grown neonates using either curve.

CONCLUSION

Three-dimensional power Doppler indices of the uteroplacental circulation space in the first trimester are similar between neonates who develop growth restriction and those who will grow normally.
