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

Abstract

Poster abstracts 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 4.1 th 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 5 th min 8, 10 th 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.

Role of Doppler indices in prediction of perinatal outcome in preeclampsia

“…However the predictive value for the subsequent development of adverse perinatal outcome does not seem to be clinically relevant. 9 In our study we observed that bilateral uterine artery pulsatility index has got maximum specificity for both major and minor adverse outcome among other uterine artery indices.…”
