RESUMO

Chorionic villus sampling (CVS) has a promising future about early detection of fetal abnormalities. It has the potential to become a major tool in the prenatal diagnosis and therapy of genetic disorders. Villus samples can be analyzed by means of cytogenetic, biochemical or molecular technics. Information available at present indicates fetal loss rate should be in the same proportion than amniocentesis. CVS appears to be a reasonably safe and reliable method of prenatal diagnosis in the first trimester of pregnancy. This procedure is setting as fast as it is possible like an excellent alternative to amniocentesis.
