Nuchal translucency: an ultrasound marker for fetal chromosomal abnormalities.
CONTEXT The literature shows an association between several ultrasound markers and chromosome abnormality. Among these, measurement of nuchal translucency has been indicated as a screening method for aneuploidy. The trisomy of chromosome 21 has been most evaluated. OBJECTIVE To define the best fixed cutoff point for nuchal translucency, with the assistance of the ROC curve, and its accuracy i...
متن کاملImpact of holoprosencephaly, exomphalos, megacystis and increased nuchal translucency on first-trimester screening for chromosomal abnormalities.
OBJECTIVES To examine the prevalence of alobar holoprosencephaly, exomphalos, megacystis and nuchal translucency thickness (NT) ≥ 3.5 mm, the incidence and types of chromosomal abnormalities associated with these conditions and their overall impact on the rate of invasive testing and performance of screening at 11-14 weeks. METHODS This was a prospective screening study for trisomies 21, 18 a...
متن کاملIs there an association between increased nuchal translucency and autism?
Methods The study included all singleton infants born in Denmark, who had routine first trimester screening between January 1st 2008 and March 31st 2012. Children were divided into three groups by NT thickness: NT > 99th percentile (group 1), NT 95th-99th percentile (group 2), and NT < 95th percentile (group 3). Follow-up was undertaken for all children at 2 to 6 years of age, depending on date...
متن کاملIncreased Nuchal Translucency and Pregnancy Outcome
BACKGROUND To study the outcome of cases with nuchal translucency (NT) ≥ 95th centile in the first trimester of pregnancy. METHODS This cross sectional study was performed at Iranian Fetal Medicine Foundation (FMF) between January 2009 and December 2011. Totally, 186 cases with NT≥ 95th centile who attended for the first trimester screening were studied. All cases with increased NT including ...
متن کاملOutcome of pregnancies with increased nuchal translucency
Methods A total of 1490 pregnant women were assessed for first trimester ultrasonography. They had routinely measured crown-rump length (CRL) and nuchal translucency (NT) for screening for Down syndrome between 11 and 14 weeks of gestation. Cases with a NT≥3 mm were counselled further regarding the risk of chromosomal abnormality and prenatal diagnosis by fetal karyotyping. A complete follow-up...
