COMBINED APPLICATION OF FETAL NUCHAL TRANSLUCENCY THICKNESS AND NASAL BONES LENGTH IN PRENATAL IDENTIFICATION FOR DOWN SYNDROME AT 11-14 WEEKS OF GESTATION
Nuchal translucency thickness and nasal bones length were prospectively evaluated in 148 fetuses with Down syndrome at 11-14 weeks of gestation. The effectiveness of prenatal ultrasound screening for Down syndrome by combination of fetal nuchal translucency thickness and nasal bone length at 11-14 weeks of gestation was 86,5 %.
