"Chorionic villus" refers to tiny finger-like structures that grow from the placenta during pregnancy. They help provide oxygen and nutrients to the developing baby inside the womb. Full definition

Just like chorionic villus sampling (CVS), a procedure done in the first trimester, amniocentesis produces a karyotype — a picture of your baby's chromosomes — so that your caregiver can see for sure if there are problems.
Trisomy 16 or mosaic trisomy 16 can also be diagnosed during pregnancy through chorionic villus sampling (CVS) or amniocentesis.
If chorionic villus sampling shows a lethal trisomy but the embryo is alive, then it is likely that the embryo has reverted to disomy.
But sometimes people inherit 24 chromosomes from one parent and 22 from the other, and this can have important implications for interpretation of the results of antenatal tests such as chorionic villus sampling.
Only chorionic villus sampling and amniocentesis can definitely detect or rule out fetal genetic abnormalities, but these are invasive to the pregnancy and carry a risk of miscarriage.
Between the 11th and 14th weeks of pregnancy, mothers may be offered chorionic villus sampling (CVS), a test that involves removing and analysing cells from the placenta.
Diagnostic tests such as amniocentesis or chorionic villus sampling provide a «yes» or «no» answer but come with a small risk for miscarriage.
You may also be advised to have a further test carried out, Chorionic Villus Sampling (CVS) which checks for inherited conditions such as Cystic Fibrosis.
The American College of Obstetricians and Gynecologists (ACOG) now recommends genetic testing by either screening (NIPT) or diagnostic testing (amniocentesis or chorionic villus sampling), for every pregnant woman.
As early as the first trimester, doctors can take a sample of placental tissue (chorionic villus sampling, or CVS) to detect whether a baby has the genes that would lead to sickle cell anemia or sickle cell trait.
The two most common forms of genetic testing are amniocentesis or chorionic villus sampling (CVS).

RhoGAM, or Rh - immune globulin, is an injection given to Rh negative women during their 28th week of pregnancy and then again within 72 hours of birth, miscarriage, amniocentesis or chorionic villus sampling.
The trade - off is that there is a potential risk to your baby from the amniocentesis or chorionic villus sampling (CVS).
Chorionic villus sampling examines fetal cells collected from the placenta — specifically, from these tiny fingerlike spidery things called chorionic villi.
Week 11: Chorionic Villus Sampling (CVS), the diagnostic test for chromosomal disorders such as Down syndrome, is usually performed between weeks 10 and 12.
If successful, this would reduce the need for invasive procedures such as amniocentesis and chorionic villus sampling but still enable women to find out accurate information regarding their baby's health early in pregnancy.

The daughters of the disomic cell then formed the body of the embryo, while the remaining trisomic cells formed the chorionic villus.
At the moment, prenatal diagnosis for a small number of genetic conditions is usually done from fetal cells that doctors capture from fluid in the womb (amniocentesis) or a snippet of placental tissue (chorionic villus sampling).
