CHORIONIC VILLI BIOPSY

CHORIONIC VILLI BIOPSY – Purposes, Indications, Client Preparation, Procedure, Factors Affecting Diagnostic Results and Client Teaching (Maternal and Child Health Nursing)

Chorionic villi biopsy (CVB) can detect early abnormalities. Fetal cells are obtained by section from finger like projections around the embryonic membrane, which eventually becomes the placenta. The test is performed between the eighth and tenth weeks of pregnancy. After the tenth week, maternal cells begin to grow over the villi. The advantages of CVB over amniocentesis are that CVB may be performed earlier, and results can be obtained in a few days and not weeks. CVB can diagnose chromosomal and bio-chemical fetal disorders

PURPOSES

To detect chromosomal discharges
