Incidence 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 کاملEvaluation of Nuchal Translucency Measuremen in First Trimester Pregnancy
Background A significant number of pregnancies, particularly in women with previous histories of infertility, are associated with fetal abnormalities. Methods such as the nuchal translucency (NT) measurement enable us to identify more pregnancies with chromosomal abnormalities. MaterialsAndMethods This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestation, ...

Background: To evaluate the association of increased fetal nuchal translucency( NT) and adverse pregnancy outcomes. Materials and Methods: In a prospective study, 2221 women who were conceived after Assisted Conception were investigated by sonography independent of multiplicity between 11 and 13 weeks' gestation. We performed 2899 NT examinations during the study period(21 March 2010 to 21...
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...
