First-trimester Down's syndrome screening using nuchal translucency: a prospective study in patients undergoing chorionic villus sampling

Nuchal translucency measurement in first trimester Down syndrome screening.

(1) Approximately three in every four fetuses with Down syndrome have increased nuchal translucency (NT), which is a larger than normal build-up of fluid at the back of the neck. (2) The ultrasound measurement of NT between 11 and 14 weeks' gestation, in combination with the mother's age and the levels of placental biochemical markers in her blood, can be used to detect approximately 84% of fet...

Evaluation of Nuchal Translucency Measuremen in First Trimester Pregnancy

Background A significant number of pregnancies, particularly in women with previous histories of infertility, are associated with fetal abnormalities. Methods such as the nuchal translucency (NT) measurement enable us to identify more pregnancies with chromosomal abnormalities. MaterialsAndMethods This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestation, ...
