[Fetography and amniography in prenatal diagnosis of genetic disorders]

68 patients were transfered to the prenatal diagnosis. Both the alpa-fetorotein-estimation and the fetography or amniography were performed in 13 patients. The indication for fetography is the exclusion of neural tube defects and other serious visible defects. The amniography can especially carried out in the prenatal diagnosis of defects of intestinal tract. A program is proposed to the prenatal detection of neural tube defects: 1. Examination of all of the pregnacies with ultra sonic B scan. 2. At suspicions ultra sonic B scan and after birth of a child with neural tube defect alpha-fetoproteinestimation at the 16th week of pregnancy and fetography at the 24th week of pregnancy.
