[Screening for chromosomal anomalies of the fetus between 11-14 gestational weeks. Review of literature].
The aim of the review is to provide an up-to-date overview of the possibilities for prenatal screening for chromosomal fetal anomalies between 11-14 weeks of gestation. A specific ultrasound marker in the first trimester, known as fetal nuchal transluceny [NT], is described. The usefulness of fetal NT as a screening tool for chromosomal anomalies, some structural anomalies, rare genetic syndromes and adverse pregnancy outcome is discussed.
