Description

Chorionic villus sampling (CVS) is a form of prenatal diagnosis to determine genetic abnormalities in the fetus. It entails getting a sample of the chorionic villus (placental tissue) and testing it. It is generally carried out only on pregnant women over the age of 35 and those who have a higher risk of Down syndrome and other chromosomal conditions. The advantage of CVS is that it can be carried out 10-12 weeks after the last period, earlier than amniocentesis (which is carried out at 15-18 weeks). However, it is more risky than amniocentesis, with a 1 in 100 to 200 risk that it will cause a miscarriage.[ citationneeded ] The CVS procedure does have risks. There is a risk of infection and Amniotic Fluid leakage. The resulting Amniotic Fluid leak can develop into a condition known as Oligohydramnios which is low Amniotic Fluid Level.
