> Amniocentesis, early diagnosis of fetal abnormalities

In recent years, through the use of ultrasound and the application of genetic techniques, it is now possible to diagnose early any congenital abnormalities of the product of conception.

The amniocentesis test consists of taking, starting from the 16th week, a small amount; of amniotic fluid, that is; the liquid that surrounds and protects the fetus.  

In the amniotic fluid, it is possible to find the cell cutenee of the unborn child.

analysis of The chromosomes of such cells allows the early diagnosis of the sex and the numerous chromosomal abnormalities (but not all!) congenital or acquired, that appear at birth in the form of various diseases.

amniocentesis is a simple and painless, however, is the high cost, both for the risk of small for the mother and for the fetus, is reserved for selected cases are shown below:


  • All pregnant patients of age greater than 35 years   
  • the

  • pregnant women who have già children with chromosomal abnormalities   
  • the presence of chromosomal abnormalities in one of the parent   
  • the presence of Down’s Syndrome (mongolism) or other chromosome abnormalities in a close relative of one of the parents   
  • the

  • index of elevated risk highlighted by the bi-test, or from the tri-test   
  • the

  • fetal abnormalities detected ultrasonographically   

a few years &it is possible to use a new technique for very early diagnosis to be made, starting from the eighth week of pregnancy, called “chorionic villus sampling“, by means of which it is possible to diagnose certain fetal anomalies, congenital (for example, Cooley’s anaemia, which is a severe form of microcitemia).

The chorionic villus sampling consists of taking a small fragment of tissue, the chorionic, that is; of that tissue will becomeà the placenta.  The directions are almost the same as amniocentesis; being moderately more risky of the amniocentesis should be made only for cases of extremely selected.

its undeniable advantage is in the precocità of the diagnosis.

another examination that is performed for the screening of Down’s syndrome and has the advantage of being non-invasive, is the study of the “nuchal Translucency” , which consists in the measurement by ultrasound of the thickness of the subcutaneous tissue retronucale of the fetus. This examination, if associated with the bi-test, può reach a sensitivityà of the 95%.
