title: [Nuchal cord and nuchal translucency measurements between 10th and 14th weeks of gestation].
abstract: Our objective was to determine the incidence of nuchal cord and it's possible influence on the nuchal translucency (NT) measurements between 10th and 14th week of gestation. One hundred fourteen singleton pregnancies were studied with transvaginal sonography. Nuchal translucency was measured according to the criteria published by Snijders et al. from the Fetal Medicine Foundation. Nuchal cord was detected with color Doppler flow mapping in 8 of 114 fetuses (7.01%). Mean cord thickness in these fetuses was 1.1 mm (range 0.5-1.4 mm). Mean nuchal translucency with and without umbilical cord were 1.67 mm (SD = 0.67; range: 0.5-3.6) and 1.59 mm (SD = 0.54; range: 0.5-3.0), respectively. The differences were statistically significant (p = 0.0146, Student's t-test for paired observations). We conclude that although relatively infrequent, nuchal cord might have influence on nuchal translucency measurements at the end of the Ist trimester.
