Prospect for vaginal delivery of growth restricted fetuses with abnormal umbilical artery blood flow.
BACKGROUND The best mode of delivery in cases of intrauterine growth restriction (IUGR) with umbilical artery blood flow changes is not well elucidated. OBJECTIVE To evaluate outcome in IUGR with umbilical artery blood flow changes planned for vaginal delivery after a negative oxytocin challenge test (OCT). METHODS In 84 term singleton pregnancies with suspected IUGR and no unanimous indica...
متن کاملReduced placental volume and flow in severe growth restricted fetuses
OBJECTIVES To evaluate placental volume and vascular indices in pregnancies with severe fetal growth restriction and determine their correlations to normal reference ranges and Doppler velocimetry results of uterine and umbilical arteries. METHODS Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, inc...
متن کاملIntracerebral regional distribution of blood flow in response to uterine contractions in growth-restricted human fetuses.
OBJECTIVE To explore middle cerebral artery (MCA) and anterior cerebral artery (ACA) blood flow responses to superimposed acute hypoxemia in growth-restricted fetuses with and without established brain-sparing flow during basal conditions. MATERIAL AND METHODS 47 term fetuses suspected of growth restriction were exposed to an oxytocin challenge test with simultaneous cardiotocography and Dopp...
متن کاملHemodynamic Impact of Absent or Reverse End-Diastolic Flow in the Two Umbilical Arteries in Growth-Restricted Fetuses
OBJECTIVE To determine if bilateral absent or reverse end-diastolic (ARED) flow in the two umbilical arteries (UAs) at the perivesical (PVC) segment represents a more severe degree of hemodynamic compromise than unilateral ARED flow at the PVC segment in singleton pregnancies complicated by intrauterine growth restriction (IUGR). METHODS This was a prospective observational study. One hundred...
متن کاملUterine and umbilical artery Doppler are comparable in predicting perinatal outcome of growth-restricted fetuses.
OBJECTIVE To compare umbilical and uterine artery Doppler in predicting outcome of pregnancies suspected of fetal growth restriction (FGR). DESIGN A prospective study included 353 singleton pregnancies complicated by an FGR fetus. SETTING University Hospital setting. SAMPLE Pregnancies suspected of FGR diagnosed by ultrasound fetal biometry during a 5-year period. MAIN OUTCOME MEASURE P...
