title: [Possibilities of the diagnosis of abnormalities within the scope of basic obstetrical ultrasound examination].
abstract: The possibility to diagnose slight masked malformations increased in the last years both by improving technical ultrasonic equipment and progressive personal experience of the examiners. With regard to time and technique it is impossible to treat fully all possibilities of ultrasonics, because the time-patient-ratio would be to enormous, the malformation rate would be to low and not any malformation is followed by an obstetric consequence. Additionally most of the malformations can be diagnosed or excluded only in determined gestational weeks. Therefore we present as a compromise a checklist which guarantees as well as examination of 8-10 patients per hour as a detection of the most important malformations. Abnormalities like double monsters, hydrocephalus, anencephaly, microcephalus, posterior and anterior tumors, thoracal and abdominal cysts, micromely and amely should not escape. Smaller abdominal cysts caused by filled intestines are very frequent. Controlling these findings, like looking for defects of extremities e.g. dub-feet is impossible, but not necessary, too, because of the lacking antenatal consequences.
