Chorionic Villi Biopsy is pronounced /kɔːrɪɒnɪk ˈvɪlaɪ baɪˈɒpsi/. The spelling of this medical term can be explained by breaking it down into its individual components. "Chorionic" refers to the chorion, which is a membrane that surrounds the developing embryo. "Villi" are tiny, finger-like projections found on the surface of the chorionic membrane. "Biopsy" is a medical procedure that involves removing a sample of tissue from the body for analysis. Therefore, Chorionic Villi Biopsy is a procedure that involves obtaining a sample of tissue from the chorionic membrane of a developing embryo for testing.
Chorionic Villi Biopsy is a medical procedure that involves the extraction of a small sample of tissue from the chorionic villi, which are tiny finger-like projections in the placenta. This diagnostic test is typically performed during early pregnancy, between the 10th and 13th week, to obtain information about the genetic makeup of the fetus and to evaluate any potential abnormalities.
During the procedure, a thin needle or catheter is inserted through the mother's abdomen or cervix, guided by ultrasound imaging to reach the placenta. A small sample of chorionic villi is then obtained by either suction or a small cut from the placenta. The collected tissue sample contains fetal cells and genetic material that can be analyzed in a laboratory setting.
Chorionic Villi Biopsy is primarily conducted to detect genetic disorders, such as chromosomal abnormalities like Down syndrome, or to identify genetic disorders that may run in families. It can also provide valuable information about the sex of the fetus and may be used for paternity testing.
Although Chorionic Villi Biopsy offers important genetic information, it carries a slight risk of complications, including miscarriage, infection, or potential damage to the fetus or placenta. Therefore, it is typically offered to pregnant women who have a higher risk for genetic disorders or those who have received abnormal results from other prenatal screening tests. Counseling and informed consent are essential before undergoing this procedure to ensure the potential risks and benefits are fully understood.
