P01.19: First-trimester screening by nuchal translucency measurement in an unselected Lebanese population

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...

First-trimester Down's syndrome screening by fetal nuchal translucency measurement in Taiwan.

BACKGROUND Fetal nuchal translucency (NT) measurement is now widely used in many Western countries as a screening tool for Down's syndrome during the first trimester. However, at present there is no data on its use in Taiwan. The purpose of the present study was to evaluate the efficacy of NT measurement in first-trimester Down's syndrome screening in Taiwan. METHODS We conducted a prospectiv...

Evaluation of Nuchal Translucency Measurement 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. MATERIALS AND METHODS This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestati...
