Prenatal Diagnosis, Sampling of Chorionic Villi
Prenatal diagnosis with application of the Amniotic fluid (Amniocentesis: AC) and chorionic villi sampling {CVS) is a general aspect of application in Human Genetics which facilitate the diagnosis of different Genetic defects, enclosing chromosomal abnormalities and Genosomopathies. Diagnosis of Genetic defects for AC and CVS is between 16-20th and 8-12th weeks of gestation respectively. Allica...
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...

Methods such as the nuchal translucency (NT) measurement enable us to identify more pregnancies with chromosomal abnormalities. MaterialsAndMethods This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestation, ...

BACKGROUND To study the outcome of cases with nuchal translucency (NT) ≥ 95th centile in the first trimester of pregnancy. METHODS This cross sectional study was performed at Iranian Fetal Medicine Foundation (FMF) between January 2009 and December 2011. Totally, 186 cases with NT≥ 95th centile who attended for the first trimester screening were studied. All cases with increased NT including ...
متن کاملchromosomally and anatomically normal fetuses with increased first trimester nuchal translucency conceived by icsi
nuchal translucency (nt) measurements in the first trimester screening between 11 and 14 weeks’ gestation are regarded as a clear marker for aneuploidies. the presence of a thickened nt, even if the karyotype is normal, can be associated with structural abnormalities. having an abnormal screening of nt, parents and physicians could face dilemma over abortion particularly in a case of ivf/icsi f...
