[Results of invasive and pharmacosonographic studies in pregnancy (I)]

In prenatal diagnosis besides radiographic methods there is a growing trend towards the use of invasive diagnostic techniques. These techniques have proved to be suitable for early detection of genetically determined conditions, diseases, and malformations of different origin. Invasive examination techniques were applied to 1.104 cases of prenatal diagnosis at Humboldt-University, Berlin, School of Medicine (Charité), Department of Gynaecology and Obstetrics, from January 1st, 1985, up to September 30th, 1987. In this paper importance and possible applications of these methods have been reported.
