Nuchal translucency in normal fetus and its variation with increasing crown rump length (CRL) and gestational age.
BACKGROUND Nuchal translucency (NT) is the fluid collection behind the fetal neck which can be measured by ultrasound at 11-14 weeks of gestation. Increase in the nuchal translucency thickness is associated with various congenital anomalies. OBJECTIVE To study the relationship between nuchal translucency thickness, crown rump length and gestational age in normal fetus. METHODS Prospective a...
متن کاملNuchal translucency thickness and crown rump length discordance for the prediction of outcome in monochorionic diamniotic pregnancies.
BACKGROUND Ultrasonographic features of the underlying hemodynamic changes in twin-twin transfusion syndrome (TTTS) may be present at the first trimester scan. AIMS To investigate the value of intertwin discordance in nuchal translucency (NT) thickness and crown-rump length (CRL) to predict TTTS and other adverse outcomes. STUDY DESIGN Cohort study. SUBJECTS One hundred and thirty-five un...
متن کاملNuchal translucency and gestational age.
Professor Wald and his team (Wald et al., 2004) have remodelled the already modelled SURUSS data (Wald et al., 2003a) to claim, firstly, that their results are now similar to those of the multicentre study co-ordinated by the Fetal Medicine Foundation (Snijders et al., 1998), and, secondly, that the gestation of choice for nuchal translucency (NT) measurement is 10 weeks. The latest modelling e...
متن کاملNuchal translucency in multiple pregnancies.
AIM To evaluate the prevalence of increased nuchal translucency (NT) in multiple pregnancies and its relation to fetal karyotype and pregnancy outcome. METHODS We measured fetal nuchal translucency (NT) in 6,338 women pregnant from 10+3 to 13+6 weeks by ultrasound and evaluated the prevalence of NT=95th centile in 115 multiple pregnancies, including 100 pairs of twins (70 dichorionic and 30 m...
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...
