P08.15: The role of uterine artery pulsatility index for prediction of outcome in pregnancies complicated by pre‐eclampsia

Abstract

newborn, umbilical artery power Doppler with zero or reverse enddiastolic blood flow (blood flow class IIIa/IIIb) or changes in venous duct blood flow. We collected data about pregnancy, prenatal ultrasound examinations and result of pregnancy. Results: 20 pregnancies were included. All women underwent caesarian section. Indication was severe maternal complication, worsening of power Doppler or deterioration of the fetus. 4 children died in postnatal period, 3 have some birth defects. Mean time of first ultrasound was 29+2g.w.11 fetuses had zero flow and 6 had reverse enddiastolic blood flow in umbilical artery. Mean estimated body weight was on 4.1th centile, mean pulsatile index in umbilical artery 2.39 (SD0.32) and cerebroplacental ratio 0.65 (SD0.18). Mean gestation week at delivery 29+5g.w, fetal body weight 891 g, Apgar score at 5th min 8, 10th min 9, arterial pH7.25 (SD1.69) and venous pH7.3 (SD1.63). Conclusions: Management of perinatal care of early onset IUGR with signs of blood flow redistribution is based on values of pulsatile index of umbilical artery, medial cerebral artery, venous duct and its pattern. Extreme or severe prematurity and maternal hypertensive complication are important factors.
