Relationship between arterial and venous Dopplar and perinatal outcome in pregnancy women with severe preeclampsia

Abstract

The aim of this study was to assess the relationship between abnormal arterial and venous Doppler finding and the perinatal outcome of fetuses in severe preeclamptic pregnancy Methods: Dopplar velocimetry of the umbilical artery(UA) and ductus venosus(DV) was performed in 32 pregnancy women who with severe preeclampsia. Groups based on the Dopplar examination were: 1 = no absent end diastolic velocity of umbilical artery[UA AEDV(-)] (n = 25, 67.6%), 2 = absent end diastolic velocity of the umbilical artery noted [UA AEDV(+)] but no reverse of ductus venosus[DV(-)] (n = 7, 18.9%), 3 = absent end diastolic velocity of umbilical artery [UA AEDV(+)] and reverse of ductus venosus [DV(+)] were both noted (n = 5, 13.5%). Apgar score at delivery, respiratory distress (RDS), intraventricular hemorrhage(IVH), necrotizing enterocolitis (NEC), send to intensive care unit (ICU) or not were recored. Results: There were no significant difference about maternal age, gestational age at delivery, maternal blood pressure, mode of delivery,baby body weight at delivery, Apgar score at delivery between three group. There were no significance difference about the perinatal outcome, including perinatal death(p = 0.56), respiratory distress syndrome(p = 0.28), intraventricular hemorrahge (p = 1.00), in three group. We could noticed higher incidence of the baby send to ICU in group 2 and 3 (p = 0.28). Conclusions: According to this study, higher incidence of the baby send to ICU in severe preeclamtic pregnant women who with abnormal dopplar finding at umbilical artery and ductus venosus. The timing of delivery of severe preeclamptic pregnancy before absent end diastolic velocity of UA is needed to think about it. But further research or more sample size is needed to confirm this finding.
