Fetal Umbilical Vein Flow in the Classification of Fetuses with Growth Restriction

Objectives: To assess umbilical vein (UV) blood flow in fetal growth restriction (FGR) and pregnancy with small for gestational age (SGA) fetus. evaluate the predictive capacity of UV (QUV) discrimination SGA fetuses from FGR before after 32 weeks pregnancy. Methods: Sixty-five women a recent diagnosis or were enrolled underwent complete Doppler examination comprehending QUV. We collected (n = 34), early-FGR 9), late-FGR 22) fetuses. Results: diameter was lower early compared to SGA, while time-averaged maximum velocity (TAMXV) only early-FGR. QUV corrected estimated weight (cQUV) significantly SGA. The receiver operating characteristic (ROC) curves analysis cQUV showed significant weeks. Conclusions: evaluation allows distinguishing FGR. assessment should be taken into consideration future research new parameters differentiate
