Contribution of ductus venosus Doppler in first-trimester screening for major cardiac defects.
OBJECTIVE To determine whether assessment of ductus venosus flow at 11-13 weeks' gestation improves the detection rate of cardiac defects achieved by screening with nuchal translucency (NT) thickness. METHODS Prospective first-trimester screening for aneuploidies, including measurement of fetal NT and assessment of ductus venosus flow. The performance of different combinations of increased fe...
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...

OBJECTIVE To assess a possible relationship between ductus venosus blood flow abnormalities and cardiac defects in chromosomally normal fetuses with increased nuchal translucency thickness at 10-14 weeks of gestation. METHODS Ductus venosus Doppler ultrasound blood flow velocity waveforms were obtained at 10-14 weeks' gestation immediately before fetal karyotyping in 200 consecutive singleton...
متن کاملDuctus venosus in the first trimester: contribution to screening of chromosomal, cardiac defects and monochorionic twin complications.
In the first trimester the ductus venosus can be easily identified with color Doppler and a ductus venosus waveform can be obtained by pulsed Doppler. At 11-13 weeks the prevalence of abnormal a-wave in the ductus venosus is inversely related to fetal crown-rump length and maternal serum pregnancy-associated plasma protein-A (PAPP-A), increases with fetal nuchal translucency (NT) thickness and ...
متن کاملretrograde ductus venosus atrio-wave as a specific predictor of perinatal mortality: a case report
as fetal compensation against hypoxemia progresses, the afterload on the heart and peripheral vascular resistance increases. eventually, the right heart fails, which is transmitted to the fetal venous system, causing decreased flow during late diastole or atrial contraction and increased resistance in the ductus venosus and inferior vena cava. the ductus has forward flow during atrial contracti...
