How is chorionic villus sampling performed?

Chorionic villus sampling (CVS) is performed by inserting a thin needle or catheter through the abdomen or cervix to collect a small sample of chorionic villi from the placenta. This sample is then sent to a laboratory for genetic analysis.

Chorionic villus sampling (CVS) is typically performed by inserting a thin tube or needle through the mother's abdomen or cervix to reach the placenta. A small sample of cells is then collected from the chorionic villi, which are tiny finger-like projections on the placenta. This sample is then sent to a laboratory for genetic testing. The procedure is usually guided by ultrasound to ensure proper placement of the needle and to monitor the fetus during the sampling process.

Chorionic villus sampling (CVS) is typically performed by a healthcare professional, often an obstetrician or a specially trained technician. The procedure involves the following steps:

1. The woman is usually lying down on an examination table.
2. The healthcare provider may use ultrasound to locate the position of the placenta and the chorionic villi, which are tiny finger-like projections on the placenta.
3. The healthcare provider then inserts a thin tube or a needle through the woman's abdomen or cervix to reach the chorionic villi.
4. A small sample of the chorionic villi is then collected using gentle suction or by directly aspirating tissue into a syringe.
5. The sample is then sent to a laboratory for genetic analysis.
6. After the procedure, the woman may be monitored for a short period to ensure there are no immediate complications.

It's important to note that the specific technique and approach may vary depending on the healthcare provider and the woman's individual circumstances. Additionally, risks and benefits should be discussed with a healthcare provider prior to undergoing chorionic villus sampling.
