[Sonographic detection and consequences of prenatally recognizable abnormalities]

Four cases of a fetal malformation and the antenatal diagnosis by ultrasound are reported (omphalocele, hydronephrosis, hydrocephaly, esophagus atresia). In our clinic about 50% of all fetuses with a malformation presented one of the reported anomalies. The obstetric, neonatale and surgical cooperation is essential in the management of the delivery and will improve fetal outcome. Frequently associated malformations are discussed.
