What is Chorionic Villus Sampling in Pregnancy?

Chorionic villus sampling (CVS) is a prenatal diagnostic procedure performed during early pregnancy to gather genetic information about the developing fetus. It involves the extraction of a small sample of tissue from the placenta, known as chorionic villi, for genetic testing. These villi contain genetic material that is representative of the fetus, allowing for the detection of chromosomal abnormalities and genetic disorders.

The procedure of Chorionic villus sampling in pregnancy is typically recommended between 10 to 13 weeks of gestation, offering an earlier alternative to amniocentesis for prenatal genetic testing. Chorionic villus sampling in pregnancy is often suggested for pregnant individuals who have an increased risk of genetic conditions or chromosomal abnormalities, such as advanced maternal age, a family history of genetic disorders, or abnormal results from other prenatal screening tests.

During Chorionic villus sampling in pregnancy, a thin needle or catheter is carefully inserted either through the abdomen (transabdominal CVS) or the cervix (transcervical CVS) to reach the chorionic villi. A small sample of tissue is then extracted and sent to a laboratory for genetic analysis. Results from the genetic testing can provide valuable insights into the health and development of the fetus, helping expectant parents make informed decisions about their pregnancy and potential medical interventions.

While Chorionic villus sampling in pregnancy offers the advantage of early detection of genetic conditions, it’s essential to weigh the benefits against the risks associated with the procedure. Your healthcare provider will discuss these considerations with you and help you determine whether Chorionic villus sampling in pregnancy is the right choice for your prenatal care.

Why is CVS Performed?

Chorionic villus sampling in pregnancy is performed for various reasons, primarily to detect genetic abnormalities or chromosomal disorders in the developing fetus. Here are some specific reasons why Chorionic villus sampling may be recommended:

• Advanced Maternal Age: Women who are 35 years or older at the time of delivery have an increased risk of having a baby with chromosomal abnormalities, such as Down syndrome. Chorionic villus sampling is often recommended for older mothers to assess the genetic health of the fetus.
• Family History of Genetic Disorders: If either parent has a known genetic disorder or there is a family history of certain genetic conditions, Chorionic villus sampling in pregnancy may be recommended to determine if the fetus has inherited the disorder.
• Abnormal Prenatal Screening Test Results: If other prenatal screening tests, such as non-invasive prenatal testing (NIPT) or ultrasound, indicate a higher risk of chromosomal abnormalities or genetic conditions, Chorionic villus sampling in pregnancy may be performed to confirm the results and provide more detailed genetic information.
• Previous Child with Genetic Disorder: If a previous child was born with a genetic disorder or chromosomal abnormality, Chorionic villus sampling in pregnancy may be recommended for subsequent pregnancies to assess the risk of recurrence.
• Parental Carrier Screening: In cases where both parents are carriers of a genetic condition, Chorionic villus sampling in pregnancy can be used to determine if the fetus has inherited the condition.
• Parental Anxiety or Concerns: In some cases, parents may opt for Chorionic villus sampling in pregnancy due to personal or familial anxiety about the possibility of genetic conditions, even in the absence of specific risk factors.

Overall, the decision to undergo Chorionic villus sampling in pregnancy is based on a combination of factors, including maternal age, medical history, family history, and individual preferences. It’s essential for expectant parents to discuss their concerns with their healthcare provider to make an informed decision.

Procedure for Chorionic Villus Sampling

The procedure for chorionic villus sampling in pregnancy involves several steps and typically takes place in a medical facility specializing in prenatal testing.

• Preparation: Before the procedure begins, you’ll have an opportunity to discuss any questions or concerns with your healthcare provider. It’s essential to inform them of any medications you’re taking, allergies you have, or medical conditions you’re experiencing. You may also receive instructions on fasting or emptying your bladder before the procedure, depending on the method chosen for chorionic villus sampling in pregnancy.
• Positioning: You’ll be asked to lie down on an examination table, typically in a gynecological or ultrasound room. Depending on the method of chorionic villus sampling in pregnancy chosen (transcervical or transabdominal), you may be positioned differently. For transcervical CVS, you’ll likely lie on your back with your feet in stirrups, similar to a pelvic exam. For transabdominal CVS, you’ll lie on your back, and your abdomen will be exposed.
• Ultrasound Guidance: Before the chorionic villus sampling in pregnancy procedure begins, your healthcare provider will use ultrasound imaging to locate the placenta and assess its position relative to your cervix or abdominal wall. This helps ensure accurate placement of the catheter or needle during the procedure and minimizes the risk of complications.
• Sample Collection: Once the placenta’s position is confirmed, your healthcare provider will proceed with collecting a sample of chorionic villi tissue. For transcervical CVS, a thin tube called a catheter is gently inserted through the cervix and guided to the placenta under ultrasound visualization. A small amount of tissue is then suctioned into the catheter and removed for analysis. In transabdominal CVS, a needle is inserted through the abdomen and guided to the placenta under ultrasound guidance. A sample of chorionic villi is then obtained by withdrawing the needle.
• Post-Procedure Monitoring: After the sample is collected, you may be monitored for a short period to ensure there are no immediate complications, such as bleeding or cramping. Your healthcare provider may perform a brief ultrasound to confirm the procedure’s success and check for any signs of distress.
• Aftercare: Following the chorionic villus sampling in pregnancy procedure, you may experience mild cramping or discomfort, similar to menstrual cramps. Your healthcare provider may recommend resting for the remainder of the day and avoiding strenuous activity. It’s essential to follow any post-procedure instructions provided by your healthcare provider and report any unusual symptoms or concerns promptly.

Overall, the chorionic villus sampling in pregnancy procedure typically takes around 30 minutes to complete, although this may vary depending on individual circumstances. Your healthcare provider will discuss the results of the CVS test with you once they become available and provide guidance on any further steps or follow-up care that may be necessary.
