Chorionic villus sampling after the first trimester.

The purpose of this article was to evaluate the association between late CVS(placental biopsy) and complications between sampling and delivery. Late chorionic villus sampling under ultrasound guidance was carried out in 2600 (86, 7%) cases in the second trimester and 400 (13, 3%) cases in the third trimester of pregnancy. Out of 3000 late CVS, 684 (22, 8%) were performed because of suspicious ultrasonographic findings. In the 500 patients between 13 and 16 weeks of gestation color Doppler was used to investigate the uteroplacental and fetal vessels before and after late chorionic villus sampling. There were only nine (0, 35 %) spontaneous abortions four to six weeks after late chorionic villus sampling. Late CVS is a safe method of prenatal diagnosis for high-risk couples and does not significantly affect the outcome of pregnancy.
