Increased nuchal translucency in fetuses with a normal karyotype.
Sonographic assessment of nuchal translucency (NT) thickness has been recognized as an effective means of screening for trisomy 21 and other chromosomal abnormalities at 11–14 weeks of gestation. Up to 80% of aneuploid fetuses have increased NT, but this feature is also found in 5% of karyotypically normal fetuses at this stage of pregnancy (Snijders et al., 1998). As this screening test examin...
متن کاملComparative Assessment of Ultrasound Placental Findings in Small for Gestational Age and Normal-Weight Fetuses
Background Small for gestational age (SGA) refers to newborns whose birth weight is less than the 10th percentile for gestational age. The aim of this study was to provide a comparative assessment of ultrasound placental findings in SGA and normal-weight fetuses in singleton pregnant women. Materials and Methods In...
متن کاملIncreased nuchal translucency in fetuses with a normal karyotype—diagnosis and management
The use of nuchal translucency (NT) in 1992 by Nicolaides et al was a major breakthrough in screening for chromosomal aneuploidies at the end of the first trimester. However, pathological conditions other than chromosomal aneuploidies are also associated with increased NT, which can also be detected in normal fetuses. This study sought to evaluate the causes of this ultrasound sign in a group o...
متن کاملPregnancy outcome for fetuses with increased nuchal translucency but normal karyotype.
OBJECTIVE To investigate pregnancy outcome for fetuses with nuchal translucency (NT) ≥3.5 mm but normal karyotype in the Stockholm (Sweden) area. METHODS A retrospective population-based cohort study. From 2006 to 2012, fetal NT was measured in 55123 singleton pregnancies. There were 341 pregnancies with NT thickness ≥3.5 mm; 139 had a normal karyotype, 164 had an abnormal karyotype and 38 we...
متن کاملBlood Parameters in Human Fetuses with Congenital Malformations and Normal Karyotype
The acid-base balance (pH, pCO2, bicarbonate concentration) and the oxygenation level of the fetuses (pO2, SaO2) were evaluated on umbilical venous blood (UVB), taken by cordocentesis. At the same time, the glucose, lactate, free fatty acid, aceto-acetate, betahydroxybutyrate and cholesterol concentrations were measured, being essential biochemical constituents in relation to the nutritional st...
