Measurement of fetal nuchal translucency thickness by three-dimensional ultrasound.
OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...
متن کاملPathophysiology of increased nuchal translucency: a review of the literature.
First-trimester nuchal translucency (NT) measurement is a widely used technique to determine the risk of fetal aneuploidy. The aim of this review was to explore the different hypotheses on the aetiology of increased NT. Using a computerized database (PubMed), articles on the aetiology of first-trimester NT were retrieved. Furthermore, the cited references of the studied articles were used to fi...
متن کامل[Increased fetal nuchal translucency thickness and normal karyotype: prenatal and postnatal follow-up].
OBJECTIVE The aim of this study was to evaluate pregnancy and postnatal outcomes of fetuses with increased nuchal translucency thickness (NT) and normal karyotype. METHODS Two hundred seventy five fetuses with increased NT were examined with karyotyping analysis, serial ultrasound scans, echocardiography and postnatal clinical and genetic evaluation at the Fetal Medicine Unit - Department of ...
متن کاملIncreased 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 کاملIncreased Fetal Nuchal Translucency Thickness and Normal Karyotype: Prenatal and Postnatal Outcome
Nuchal translucency (NT) is the assessment of the amount of fluid behind the neck of the fetus, also known as the nuchal fold. An anechoic space is visible and measurable sonographically in all fetuses between the 11th and the 14th week of the pregnancy (Figure 1). Underlying patho‐ physiological mechanisms for nuchal fluid collection under the skin include cardiac dysfunc‐ tion, venous congest...
