chorionic villus sampling
Quick Summary
Chorionic villus sampling (CVS) is a prenatal diagnostic test performed between the 8th and 12th week of gestation. It involves taking a small sample of villi from the chorion, the outer embryonic membrane, to analyze fetal cells for chromosomal abnormalities.12
The procedure can be done through the abdomen or vagina, using ultrasound guidance. A thin catheter is inserted into the uterus to extract the villi sample.1
CVS allows for earlier detection of potential fetal issues compared to amniocentesis, enabling earlier pregnancy termination if necessary. However, it carries a slightly higher risk of fetal loss and potential concerns about limb reduction, though reports on the latter are inconclusive. The abbreviation for chorionic villus sampling is CVS.123

diagnostic tests are amniocentesis and chorionic villus sampling (CVS). In amniocentesis, a thin needle is inserted through the abdomen and uterus and into the amniotic sac. A small sample of amniotic fluid, which is rich in fetal cells, is then collected. The procedure typically is performed between 15 and 17…
