متن کاملScreening for trisomy 21 in monochorionic twins by measurement of fetal nuchal translucency thickness.
OBJECTIVE To determine whether in screening for trisomy 21 by measurement of fetal nuchal translucency (NT) thickness in monochorionic twin pregnancies it is preferable to use the higher, smaller or average NT. METHODS We retrospectively examined 769 monochorionic twin pregnancies that had undergone NT screening. The selection criteria were that first, in each pregnancy both fetuses were aliv...
