[Prenatal and postnatal diagnosis of triploidy in man (author's transl)]

Prenatal amniocentesis, chromosome analysis, as well as clinical and pathologicoanatomic approaches are some of the ways by which to diagnose triploidy. The methods are described against the background of triploidy (karyotype 69 XXX) in a bipara, 24 years of age. Prenatal examination of hydramnion, particularly in cases with concomitant gestosis, should include amnion cell culturing for early detection of triploidy. Postnatal diagnosis, in response to typical malformation of the foetus and placenta, is possible, provided that thought is given to that aspect.
