SOSA, Cristian; GOMEZ, Libardo; BERMUDEZ, Carlos  e  PEREZ-WULFF, Juan. Increased foetal nuchal translucency and reverse flow of the ductus venosus in congenital cardiopathy. Rev Colomb Obstet Ginecol [online]. 2008, vol.59, n.1, pp.57-61. ISSN 0034-7434.

Introduction: increased foetal nuchal translucency (NT) from 11 to 14 weeks’ gestation is a common phenotypicexpressionofchromosomeabnormality, including trisomy 21. Nevertheless, in the absence of aneuploidy, nuchal thickening is clinically relevant because it is associated with increased adverse perinatal result caused by a variety of foetal malformations, dysplasias, deformations, disruptions and genetic syndromes. The object of presenting this case was to show the importance of NT as a marker for different aneuploid pathologies when being above the 99^th percentile. Discussion: once the presence of aneuploidy has been eliminated, the risk of an adverse perinatal result does not become statistically reduced until nuchal measurement of translucency reaches 3.5 millimeters (99^th percentile). Risk increases exponentially as NT increases. Nevertheless, if the foetus survives, there is an increased risk of congenital cardiopathy occurring. Ultrasound at 20-22 weeks can reveal cardiac abnormality.
