Chorionic villus sampling - series—Procedure, part 2 - transabdominal

Procedure, part 2 - transabdominal

Overview

If your surgeon uses the transabdominal procedure, it will be very similar to amniocentesis. They insert a needle through your abdomen and uterus to the chorionic villi. As with the transcervical procedure, your surgeon uses ultrasound to determine the fetus' position to help guide the needle safely to the chorionic villi.
