    Abstract:
    Currently two genetic pulmonary disorders can be diagnosed before birth: alpha-1-antitrypsin deficiency and mucoviscidosis. For the latter there are two possible diagnostic techniques: first a study of the intestinal enzymes of the amniotic fluid, a reliable method only at the 18th week, and also a study of DNA markers (ADN) of the trophoblastic cells using molecular biological techniques: this can be performed from the 10th to 11th week of pregnancy but presupposes a family study in which there is already a subject suffering from the disorder. Foetal echocardiography enables various pulmonary abnormalities to be detected: pleural effusion, cyst, pulmonary hypoplasia and other disorders. This technique however has some limits, at least at present. Most often these severe malformations are revealed at birth such as respiratory distress or stillbirth. Adenomatous cystic malformations or congenital lobar emphysema, a posterior diaphragmatic hernia, and oesophageal atresia with oesophagotracheal fistula are the most frequent and are curable surgically.
