Increased fetal nuchal translucency at 11-14 weeks.
Nuchal translucency (NT) is the sonographic appearance of a subcutaneous collection of fluid behind the fetal neck. The measurement of fetal NT thickness at the 11-14-week scan has been combined with maternal age to provide an effective method of screening for trisomy 21; for an invasive testing rate of 5%, about 75% of trisomic pregnancies can be identified. When maternal serum free-beta human...
متن کاملCystic hygromas, nuchal edema, and nuchal translucency at 11-14 weeks of gestation.
OBJECTIVE To estimate the incidence of septations in fetuses with increased nuchal translucency (NT) thickness, and to investigate the relationship between the length and thickness of the translucency and whether the length or septations provide useful information concerning the fetal karyotype in addition to that provided by the NT thickness alone. METHODS We examined 386 fetuses with NT thi...
متن کاملDo early pregnancy ultrasound measurements correlate with fetal nuchal translucency at 11-14 weeks?
OBJECTIVE To assess whether extremes in nuchal translucency (NT) thickness measurements at 11-14 weeks of gestation are preceded by departures from normal in early ultrasound biometry or embryonic heart rate in euploid fetuses. METHODS This was a retrospective analysis of data from women with singleton pregnancies examined in early pregnancy between June 2002 and January 2003, who subsequentl...
متن کاملI-44: Increased Nuchal Translucency at 11-14 Weeks of Gestation As A Marker for Adverse Pregnancy Outcomes
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 کاملAnalysis of Quality of Nuchal Translucency Measurements
Objective: Quantitative analysis of the quality of nuchal translucency (NT) measurements. Methods: This is a retrospective single-center study. NT was measured according to the Fetal Medicine Foundation (FMF) criteria by 20 trained obstetricians (October 2003-November 2009). The performance of NT measurements was analyzed with regard to several quality control standards. Accuracy according to e...
