[Ultrasonographic diagnosis of a combined malformation syndrome - hydrocephalus - evisceration and dysplasia of the extremities (author's transl)].

The article reports on the ultrasonographic criteria in a complex malformation syndrome (hydrocephalus, evisceration and phocomelia of the lower extremities). Additional examination methods which are suggested whenever there is a suspicion of foetal malformation, are described. The majority of severe congenital malformations can be discovered antenatally via thorough sonographic examination of the foetus in the longitudinal and transverse axes.
