Single umbilical artery at 11-14 weeks' gestation: relation to chromosomal defects.
OBJECTIVE To determine the possible association between single umbilical artery (SUA) at 11-14 weeks of gestation and the incidence of chromosomal abnormalities. METHODS Color flow imaging of the fetal pelvis was used to determine the number of umbilical arteries in 717 fetuses immediately before chorionic villus sampling for karyotyping at 11-14 weeks' gestation. RESULTS Single umbilical a...
متن کاملUmbilical cord diameter at 11-14 weeks of gestation: relation to chromosomal defects.
OBJECTIVE To determine the potential value of measuring umbilical cord diameter (UCD) at 11-14 weeks of gestation in screening for chromosomal defects. METHODS The UCD was measured in 1323 fetuses immediately before chorionic villus sampling for karyotyping at 11-14 weeks of gestation. In the group of chromosomally normal fetuses, regression analysis was used to determine the association betw...
متن کاملAbsent nasal bone at 11-14 weeks of gestation and chromosomal defects.
OBJECTIVE To examine the association between absence of the nasal bone at the 11-14-week ultrasound scan and chromosomal defects. METHODS Ultrasound examination was carried out in 3829 fetuses at 11-14 weeks' gestation immediately before fetal karyotyping. At the scan the fetal crown-rump length (CRL) and nuchal translucency (NT) thickness were measured and the fetal profile was examined for ...
متن کاملPlacental volume measured by three-dimensional ultrasound at 11 to 13 + 6 weeks of gestation: relation to chromosomal defects.
OBJECTIVE To determine the potential value of measuring the placental volume at 11 to 13 + 6 weeks of gestation in screening for chromosomal defects. METHODS The placental volume was measured using three-dimensional ultrasound in 500 consecutive singleton pregnancies immediately before chorionic villus sampling for fetal karyotyping at 11 to 13 + 6 (median, 12) weeks of gestation. RESULTS T...
متن کاملMegacystis at 10-14 weeks of gestation: chromosomal defects and outcome according to bladder length.
AIMS To examine the prevalence of chromosomal defects and outcome of fetuses with megacystis at 10-14 weeks of gestation. METHODS At the 10-14-week scan fetal megacystis was defined by a longitudinal bladder diameter of 7 mm or more. In 145 such fetuses the fetal karyotype and pregnancy outcome were examined in relation to the longitudinal diameter of the fetal bladder. RESULTS Chromosomal ...
