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...
متن کاملEvaluation 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...
متن کاملThe assessment of nuchal translucency and serum markers for down syndrome screening with ductus venosus Doppler measurements in the first trimester.
OBJECTIVE The aim of the study was to improve nuchal translucency (NT) and serum marker Down syndrome (Tri21) screening methods by including fetal ductus venosus (DV) Doppler measurements. MATERIAL AND METHODS A total of 213 pregnant women were screened consecutively by combining maternal age, fetal NT and maternal serum pregnancy associated plasma protein A (PAPP-A) and free β-human chorioni...

متن کاملSecond-trimester soft markers: relation to first-trimester nuchal translucency in unaffected pregnancies.
OBJECTIVE Genetic sonography following first-trimester combined screening appears to increase substantially detection rates for Down syndrome but it relies on the unproved assumption of independence between these tests. In this study we aimed to investigate the relationship between first-trimester nuchal translucency (NT) and a series of second-trimester soft markers and structural defects in u...
