The significance of ultrasound diagnosis for the detection of fetal malformations will be demonstrated in 66 cases. The group includes hydrocephaly, anencephaly, microcephaly, synostosis praematura, cleft of the face, spina bifida, omphalocoele, Potter's syndrome, Down's syndrome, Klinefelter's syndrome, Vrolik's syndrome, triploidy, adenomatoide cystic malformation of the lungs, malformation of the heart and the limbs. Typical echographic findings are demonstrated. In regard to normal fetuses, head and trunk measurements will be analysed. Suspicious symptomes for the presence of malformations will be mentioned and also difficulties for the diagnosis of anencephaly and hydrocephaly. Furthermore typical findings in early pregnancy failure resulting from malformation are discussed.
