Fetal ductus venosus pulsatility index and diameter during 20-30 weeks gestation.
OBJECTIVE To present normal range of the pulsatility index and the smallest diameter in the ductus venosus in normal fetuses throughout gestation. MATERIAL AND METHOD This was a prospectively cross-sectional study. Three measurements were made for the ductus venosus diameter and the pulsatility index in each fetus during fetal quiescence. Statistical Package for the Social Sciences 14.0 softw...
متن کاملEffect of fetal gender on ductus venosus pulsatility index and diameter at gestational age 17-37 weeks.
OBJECTIVE Recent findings have suggested that ductus venosus blood flow in the first trimester may be influenced by fetal gender. The aim of the present study was to investigate further the influence of fetal gender on ductus venosus (DV) pulsatility index (PI) and diameter at gestational age 17-37 weeks. MATERIAL AND METHOD This was a cross-sectional study. Three measurements were made for e...
متن کاملDuctus venosus pulsatility index measurement reduces the false-positive rate in first-trimester screening.
OBJECTIVE To investigate if ductus venosus (DV) pulsatility index for veins (PIV) and a-wave measurements can increase the accuracy of first-trimester Down syndrome screening in a high-risk population. METHODS The database of our fetal medicine unit was searched for all cases at increased first-trimester Down syndrome risk. Multivariable logistic regression was used to construct a prediction ...
متن کاملMonitoring of fetuses with intrauterine growth restriction: longitudinal changes in ductus venosus and aortic isthmus flow.
OBJECTIVES To explore in growth-restricted fetuses the sequence of changes in aortic isthmus and ductus venosus blood flow in relation to other arterial Doppler parameters commonly used to evaluate fetal wellbeing. METHODS Umbilical and middle cerebral arteries, ductus venosus and aortic isthmus were explored serially by means of pulsed Doppler in a cohort of singleton small-for-gestational a...
متن کاملDuctus venosus Doppler in fetuses with cardiac defects and increased nuchal translucency thickness.
OBJECTIVE To examine the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for major cardiac defects in chromosomally normal fetuses with increased nuchal translucency (NT) thickness at 11 + 0 to 13 + 6 weeks' gestation. METHODS Ductus venosus blood flow velocity waveforms were obtained immediately before chorionic villus sampling for fetal karyotyping i...
