Chorionic villus sampling (CVS)

A procedure similar to amniocentesis, except that cells are taken from the chorionic membrane for testing. These cells, called chorionic villus cells, eventually become the placenta. The samples are collected either through the abdomen, as in amnio, or through the vagina. CVS can be done earlier in the pregnancy than amnio, but carries a somewhat higher risk.

Mentioned in: Amniocentesis, Cri Du Chat Syndrome, Fragile X Syndrome, Lesch-Nyhan Syndrome, Nail-Patella Syndrome, Patau Syndrome, Prenatal Surgery, Retinoblastoma, Von Willebrand Disease

chorionic villus sampling (CVS)

Etymology: Gk, L, shaggy hair, exemplum

the sampling of placental tissues for prenatal diagnosis of potential genetic defects. The sample is obtained through a catheter inserted into the cervix. One of the main advantages of having this test instead of amniocentesis is that it can be done earlier in pregnancy. Also called chorionic villus biopsy (CVB). Compare amniocentesis.
