Understanding CVS

Watch this informative video to learn more about Chorionic Villus Sampling and what to expect during the procedure.

What is CVS?

Chorionic Villus Sampling (CVS) is a prenatal diagnostic procedure that involves taking a small sample of cells from the placenta. These cells contain the same genetic material as the fetus and can be analyzed for genetic conditions and chromosomal abnormalities.

When is it performed?

  • Between 11-14 weeks of pregnancy
  • When there's an increased risk of genetic conditions
  • After abnormal screening test results
  • For advanced maternal age
  • When there's a family history of genetic disorders

What Can Be Detected?

1

Chromosomal Abnormalities

Conditions like Down syndrome and other chromosomal disorders.

2

Genetic Disorders

Single gene disorders like cystic fibrosis and sickle cell disease.

3

Metabolic Disorders

Inherited metabolic conditions and enzyme deficiencies.

What to Expect

During the Procedure

  • Ultrasound guidance for precise sampling
  • Local anesthesia for comfort
  • Small sample collection from the placenta
  • Continuous monitoring of the baby
  • Brief rest period after the procedure

After the Procedure

  • Detailed explanation of findings
  • Discussion of next steps
  • Follow-up care instructions
  • Support and counseling services
  • Access to test results
