Ductus 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...
متن کاملRelationship between nuchal translucency thickness and prevalence of major cardiac defects in fetuses with normal karyotype.
OBJECTIVE To define the prevalence of major cardiac defects according to nuchal translucency (NT) thickness at the 11 to 13 + 6-week scan in fetuses with normal karyotype. METHODS Specialist fetal echocardiography was carried in 6921 fetuses with normal or presumed normal karyotype at a median gestation of 20 (range 12-35) weeks. The indications for fetal echocardiography were increased NT th...
متن کاملIncidence of major structural cardiac defects in fetuses with increased nuchal translucency and normal karyotype
Background Nuchal translucency (NT) is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes NT thickness is increased. The aim of the study was to evaluate the incidence of major cardiac defects in relation to the fetal NT in chromosomall...
متن کاملCardiac defects in chromosomally normal fetuses with abnormal ductus venosus blood flow at 10-14 weeks.
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 کاملIncreased nuchal translucency in fetuses with a normal karyotype.
Sonographic assessment of nuchal translucency (NT) thickness has been recognized as an effective means of screening for trisomy 21 and other chromosomal abnormalities at 11–14 weeks of gestation. Up to 80% of aneuploid fetuses have increased NT, but this feature is also found in 5% of karyotypically normal fetuses at this stage of pregnancy (Snijders et al., 1998). As this screening test examin...
