Chorionic villus sampling is an office procedure. Sufficient tissue is removed 98% of the time. Your doctor will use ultrasound to guide a catheter, a long thin tube, through the cervix to the growing placenta. Gentle suction is used to removed a small amount of tissue. If there is an obstruction to the cervix, or tests returned positive for vaginal infections, a needle will be passed through the abdomen just above the pubic bone. Your doctor will use a local anesthetic for this procedure. In both cases, discomfort is similar to a pelvic exam with a speculum.
