Fetal ductus venosus Doppler as a predictor of pregnancy outcome

Background: The ductus venosus (DV) transports oxygenated blood to the developing heart and brain by avoiding hepatic circulation. Due anatomical location of DV, measurement DV flow velocity waveforms indirectly disclose cardiac functions health foetus, which represents pressure gradient between umbilical vein right atrium. aim this study was evaluate value pulstality index veins in early pregnancy prediction adverse outcomes. Methods: 50 pregnant women with a single viable foetus 13 24 weeks participated prospective cross-sectional from 2021 2022 at Tanta University Hospital. Results: PI normal group ranged 0.80-1.20 mean 0.90±0.130 abnormal 0.46-0.50 0.522±0.069. S/a ration 1.74-3.18 2.30±0.40 1.50-2.05 1.833±0.212. There statistically significant difference outcomes ultrasound findings (p<0.05). Conclusions: Numerous foetal disorders that might result cardiovascular deterioration other aberrant newborns can be managed clinically predicted perinatally using Doppler examination.
