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

Procedure, part 2 - transcervical

Overview

If your surgeon uses a transcervical procedure, he opens your vagina with a speculum and eases a thin catheter through it and your cervix.

Your surgeon then moves the catheter to the chorionic villi with the guidance of an ultrasound. He checks the fetus' position on the ultrasound screen so he can maneuver the catheter within the uterus without harming the fetus.
