Amniocentesis and chorionic villus sampling for prenatal diagnosis.

BACKGROUND A major disadvantage of second trimester amniocentesis is that the result is usually available only after 18 weeks' gestation. Chorionic villus sampling (CVS) and early amniocentesis can be done between 9 and 14 weeks and offer an earlier alternative. OBJECTIVES The objective was to assess comparative safety and accuracy of second trimester amniocentesis, early amniocentesis, trans...

Amniocentesis and Chorionic Villus Sampling

Prenatal Genetic Diagnosis through Chorionic Villus Sampling

Chor ion ic v i l l us sampl ing (CVS) i s a technique for prenatal diagnosis of the fetal karyotype through cytogenetic analysis, and of Mendelian inherited diseases through molecular or biochemical analysis. Because the sampling technique can be performed in the first-trimester of pregnancy and diagnostic results can be obtained earlier than with amniocentesis, it has been utilized by clinici...

Invasive Prenatal Diagnosis: Chorionic Villus Sampling

Chorionic villus sampling (CVS) is the method of choice for first trimester invasive prenatal diagnosis. In expert hands, it is nowadays considered as safe as amniocentesis and has the advantage of an earlier diagnosis. In this review, we des cribe the technique of the procedure, its indications and contra indications and the requirements concerning adequate training and optimum clinical practi...
