Advanced Maternal Age – Risks and Precautions
With CVS, a small sample of cells (called chorionic villi) is taken from the placenta where it attached to the wall of the uterus. Chorionic villi are tiny parts of the placenta; therefore they have the same genes as the baby. This test is 98% accurate, but can carry a slightly higher risk of miscarriage than amniocentesis, since the procedure is done in early pregnancy.
We are in a time that allows for the use of the snooze button on the biological clock, which gives women a little “extra” time.
Amniocentesis is a procedure where a sample of fluid is removed from the amniotic sac for analysis and evaluation. During this procedure, fluid is removed by placing a long needle through the abdominal wall into the amniotic sac. The amniocentesis needle is typically guided into the sac with the help of ultrasound imaging. Once the needle is in the sac, a syringe is used to withdraw the clear amber-colored amniotic fluid, which looks a bit like urine.
Both of these tests, CVS and amniocentesis, let couples know if the fetus will have genetic abnormalities, and will help them make informed decisions regarding their pregnancy.
It is amazing how far science has come. There was a time when once you were a certain age, it was said that your biological clock had ticked out and your time for having a baby had passed. We are in a time that allows for the use of the snooze button on the biological clock, which gives women a little “extra” time. Every pregnancy comes with risks, but with a little information and dedication to your health, the payoff can be amazing.
