Abstract

Introduction: nuchal translucency (TN) is observed as a hypoechoic region on ultrasound in the posterior part of the fetal cervical spine, observable at week 11-14. The Nuchal Fold (PN) shows the thickness of the skin on the back of the fetus's neck.

 Clinical case:  It is a case of a 30-year-old patient, primigravida, with no relevant history. Fetus of 13.1 weeks, with TN of 4.6 mm ductus venosus presence of antegrade wave, retrograde tricuspid valve flow. Fetal DNA test, absence of aneuploidies. At 21.4 weeks PN 6.3 mm, rest of anatomical detail within normal parameters. After cesarean section, a phenotypically normal newborn was obtained.

Conclusion: Increased TN and PN are useful ultrasound markers in the screening of chromosomal and non-chromosomal abnormalities. It should be noted that these values by themselves do not indicate pathology, but they do demarcate a risk factor for abnormality, which should be considered for more exhaustive studies.
