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 کاملA mixture model of ductus venosus pulsatility index in screening for aneuploidies at 11-13 weeks' gestation.
OBJECTIVE To assess the value of ductus venosus pulsatility index for veins (DV PIV) in screening for aneuploidies at 11-13 weeks' gestation. METHODS Fetal DV PIV was measured in singleton pregnancies undergoing first-trimester screening for aneuploidies. In euploid (n = 44,756) and aneuploid (202 cases of trisomy 21, 72 cases of trisomy 18 and 30 cases of trisomy 13) fetuses, DV PIV was best...
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 کاملScreening for chromosomal abnormalities at 10-14 weeks: the role of ductus venosus blood flow.
OBJECTIVE To assess the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for chromosomal abnormalities at 10-14 weeks of gestation. METHODS Ductus venosus flow velocity waveforms were obtained immediately before fetal karyotyping in 486 consecutive singleton pregnancies at 10-14 weeks of gestation. All cases were screened for chromosomal defects by a co...
