Fetal outcomes in first trimester pregnancies with an indeterminate ultrasound.
BACKGROUND Pregnant women commonly present to the Emergency Department (ED) for evaluation during their first trimester. These women have many concerns, one of which is the viability of their pregnancy and the probability of miscarriage. STUDY OBJECTIVES We sought to determine fetal outcomes of women with an indeterminate ultrasound who present to the ED during the first trimester of pregnanc...
متن کاملProspective first-trimester screening for trisomy 21 in 30,564 pregnancies.
OBJECTIVE This study was undertaken to evaluate the performance of a 1-stop clinic for first-trimester assessment of risk (OSCAR) for trisomy 21 by a combination of maternal age, fetal nuchal translucency (NT) thickness, and maternal serum-free ss- human chorionic gonadotrophin (hCG) and pregnancy-associated plasma protein-A (PAPP-A). STUDY DESIGN OSCAR was carried out in 30,564 pregnancies a...
متن کاملSecond-trimester soft markers: relation to first-trimester nuchal translucency in unaffected pregnancies.
OBJECTIVE Genetic sonography following first-trimester combined screening appears to increase substantially detection rates for Down syndrome but it relies on the unproved assumption of independence between these tests. In this study we aimed to investigate the relationship between first-trimester nuchal translucency (NT) and a series of second-trimester soft markers and structural defects in u...
متن کاملFirst trimester risk assessment for trisomy 21 in twin pregnancies combining nuchal translucency and first trimester biochemical markers.
OBJECTIVE The aim is to describe the performance of first-trimester combined risk assessment in twin pregnancies. METHODS Maternal serum free beta-human chorionic gonadotrophin and pregnancy-associated plasma protein A (PAPP-A) were determined at 8 to 12 weeks and fetal nuchal translucency (NT) was measured at 11 to 13+6 weeks. The individual risk was estimated for each fetus using the combin...
متن کاملFirst trimester maternal serum placenta growth factor (PIGF)concentrations in pregnancies with fetal trisomy 21 or trisomy 18.
Placenta growth factor (PIGF), an angiogenic factor belonging to the vascular endothelial growth factor family, pregnancy-associated plasma protein A (PAPP-A) and free beta-human chorionic gonadotrophin (beta-hCG) were measured in maternal serum from 45 pregnancies with trisomy 21, 45 with trisomy 18 and 493 normal controls at 10-13 completed weeks of gestation. In the normal pregnancies matern...
