Nuchal translucency in multiple pregnancies.
AIM To evaluate the prevalence of increased nuchal translucency (NT) in multiple pregnancies and its relation to fetal karyotype and pregnancy outcome. METHODS We measured fetal nuchal translucency (NT) in 6,338 women pregnant from 10+3 to 13+6 weeks by ultrasound and evaluated the prevalence of NT=95th centile in 115 multiple pregnancies, including 100 pairs of twins (70 dichorionic and 30 m...
متن کاملOutcome of pregnancies with increased nuchal translucency
Methods A total of 1490 pregnant women were assessed for first trimester ultrasonography. They had routinely measured crown-rump length (CRL) and nuchal translucency (NT) for screening for Down syndrome between 11 and 14 weeks of gestation. Cases with a NT≥3 mm were counselled further regarding the risk of chromosomal abnormality and prenatal diagnosis by fetal karyotyping. A complete follow-up...
متن کاملDown Syndrome Screening in Pregnancies Conceived after Assisted Reproductive Technologies
Over the last three decades, prenatal screening for Down syndrome and other chromosomal abnormalities has become routine during antenatal care. Down syndrome screening has changed from the second to the first trimester of pregnancy because of the higher detection rate and earlier diagnosis. Second-trimester screening, based on the combination of maternal serum human chorionic gonadotropin (hCG)...
متن کاملFirst trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction.
BACKGROUND Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) ...
متن کاملFirst-trimester serum marker distribution in singleton pregnancies conceived with assisted reproduction.
OBJECTIVE To evaluate marker distribution of free beta-human chorionic gonadotrophin (fbeta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in singleton pregnancies conceived by assisted reproduction techniques (ART). METHODS In vitro fertilization (IVF) (n = 203) and intracytoplasmic sperm injection (ICSI) (n = 192) cases from a database of 14 645 first-trimester combined tests (over...
