Chorionic villus sampling: 10 years of experience in a University referral center.

In our study the risk of miscarriage in the CVS group was not significantly different from that the expected patient specific risk (3.2% vs 3%, p = 0.7). The procedure-related risk of miscarriage was 0,2%, similar to the rates describe in the literature. An accurate risk of pregnancy loss should be used when counseling women for CVS to allow an informed decision.
