Chorionic villus tasting, or CVS, is a treatment in which a sample of chorionic villi is eliminated from the placenta for screening. Throughout pregnancy, the placenta offers oxygen and nutrients to the growing child and eliminates waste items from the infant's blood. The chorionic villi are wispy cellular forecasts that comprise the majority of the placenta and share the infant's hereditary makeup. Your healthcare service provider may suggest CVS for prenatal hereditary medical diagnosis early throughout your pregnancy.
Before the treatment, your healthcare supplier will utilize fetal ultrasound to reveal your infant's position on a screen. If the placenta remains in a beneficial position, your healthcare service provider may take the sample through your cervix. Your healthcare supplier will open your vaginal area with the speculum and place a thin, hollow tube, called a catheter, through your cervix.
When the catheter reaches the placenta, mild suction will be utilized to get rid of a little tissue sample. This is referred to as a transcervical chorionic villus tasting. If the placenta isn't plainly available through the cervix or you have a cervical infection, your healthcare service provider may take the sample through your stomach wall.
Assisted by ultrasound, your healthcare supplier will place a long, thin needle through your stomach wall and into your uterus. The tissue sample from the placenta will be withdrawn into a syringe, and the needle will be eliminated. This is called a transabdominal chorionic villus tasting. Your healthcare service provider may advise pelvic rest for about 24 hours after the treatment. Otherwise, you can typically resume your typical activities.
