[Increased nuchal translucency with normal karyotype].
Nuchal translucency (NT) measurement in first trimester screening between 11 and 14 weeks' gestation has now been clearly identified as a marker for aneuploidies and in particular for trisomy 21. Even in the absence of aneuploidy increased fetal nuchal translucency has been shown to be a marker for fetal heart malformations and numerous other fetal defects and genetic syndromes when the measure...
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...
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 کاملPregnancy outcome for fetuses with increased nuchal translucency but normal karyotype.
OBJECTIVE To investigate pregnancy outcome for fetuses with nuchal translucency (NT) ≥3.5 mm but normal karyotype in the Stockholm (Sweden) area. METHODS A retrospective population-based cohort study. From 2006 to 2012, fetal NT was measured in 55123 singleton pregnancies. There were 341 pregnancies with NT thickness ≥3.5 mm; 139 had a normal karyotype, 164 had an abnormal karyotype and 38 we...
متن کاملIncreased nuchal translucency in fetuses with a normal karyotype—diagnosis and management
The use of nuchal translucency (NT) in 1992 by Nicolaides et al was a major breakthrough in screening for chromosomal aneuploidies at the end of the first trimester. However, pathological conditions other than chromosomal aneuploidies are also associated with increased NT, which can also be detected in normal fetuses. This study sought to evaluate the causes of this ultrasound sign in a group o...
