Chorionic Villus Sampling

Chorionic villus sampling is a prenatal diagnostic procedure performed between 10 and 13 weeks of gestation to detect genetic and chromosomal conditions. The procedure involves collecting a small sample of placental tissue (chorionic villi), which contains the same genetic material as the fetus. Chorionic villus sampling offers early, definitive results for conditions such as Down syndrome and other inherited disorders. The procedure can be performed either transabdominally or transcervically, depending on the location of the placenta. Chorionic villus sampling is typically recommended for individuals with increased risk, including abnormal screening results, advanced maternal age, or a family history of genetic conditions. Although generally safe, chorionic villus sampling carries a small risk of complications, including miscarriage, making informed patient counseling essential. As prenatal testing options evolve, chorionic villus sampling remains a valuable tool for early diagnosis and decision-making. This activity reviews the indications, contraindications, risks, techniques, and utility of the procedure. Participants gain insights into patient selection, risk assessment, counseling strategies, and potential complications. The activity also highlights the role of the interprofessional team in ensuring safe, informed, and coordinated prenatal care.
