Measurement of fluid found behind the fetal neck

It's a sonographic measurement of the translucent space in the tissue at the back of the baby's neck.

Babies with chromosomal abnormalities tend to accumulate more fluid at the back of their neck during the 1st trimester, causing this clear space to be larger than average.

A Useful marker that helps screen Preeclampsia

MAP is dependent on other characteristics, most importantly maternal weight and chronic hypertension, and for its effective use in risk assessment and screening, these covariates need to be taken into account.

Measured by transabdominal/transvaginal sonography

Uterine artery Doppler flow studies during the 11th and 14th week of pregnancy are important in the prediction of preeclampsia and intrauterine growth restriction in pregnant women as well as in the prevention.

Helps in forming the blood vessels

As pregnancy progresses, PlGF levels rise and peak around 26-30 weeks’ gestation. If the levels do not rise this may indicate a problem with the placenta, which is associated with preeclampsia. In preeclampsia, levels of PlGF can be abnormally low.

Associations: Decreased Levels = High-risk probability of Preeclampsia
