Special Considerations
- CVS may be associated with an increased risk for limb anomalies in the fetus. This risk appears to be very low (1 in 3,000) when CVS is performed after 10 weeks gestational age.
- After this test, if your blood is Rh negative, you may receive RhoGAM to avoid Rh incompatibility.
- Two to 4 days after the CVS, you will be scheduled for a follow-up ultrasound, to ensure that the fetus survived the procedure.
Report any signs that there may be complications of the procedure to your health care provider:
