CVS Side Effects

Chorionic villus sampling (CVS) is a diagnostic test used to identify chromosome abnormalities during pregnancy. Indicators for testing include abnormal results during prenatal testing, a mother over the age of 35, abnormal chromosomal issues during a previous pregnancy or a family history shows either parent to be a carrier of a genetic disorder. A woman who undergoes CVS may experience some side effects.
  1. Cramping

    • Some women complain of mild cramping during the procedure with pain similar to menstrual cramps. As CVS is an invasive procedure, some mild discomfort and pinching may accompany the process. Feeling pressure is normal. However, if the pain becomes intense, tell the health-care professional performing the procedure.

    Spotting

    • Spotting is light bleeding experienced by some women during pregnancy. After the CVS procedure, a minimal amount of spotting is normal. During the test, a small amount of placenta material is removed for examination. This may result in residual blood from the site. This is not an indicator of a problem, unless the bleeding is significant. In a normal pregnancy, spotting may indicate possible miscarriage or fetal distress. Keep your physician apprised of any problems or fears you may experience.

    Infection

    • CVS involves the insertion of a catheter and other equipment into your body. While all equipment used during the procedure will be sterilized, infection is always a possibility. Call your doctor immediately if you experience fever, chills or leaking amniotic fluid. You should also keep your doctor apprised of symptoms such as worsening stomach pain.
