Severe IUGR with an estimated fetal weight barely reaching 239g at 21WG (usually approx 500g is expected at this term). All biometric parameters < 3rd percentile.
Pathological umbilical Doppler with reversed diastolic flow.
Middle cerebral artery Doppler remained normal, indicating a relative vasodilation to preserve brain from damage: vascular redistribution, with a cerebro-placental ratio < 1, RI MCA / RI umbilical <1.
Ductus venosus Doppler : A wave is flat, which reflects increased filling pressure in the right atrium.
Bilateral uterine Dopplers showed protodiastolic notch (not shown), which is a non relevant finding at this stage with obvious abnormal umbilical Doppler.
Placenta had a round shape with poor basal surface area and echoic aspect.
