[Perinatal problems in breech presentation].

543 cases of breech presentation at the 1st Clinic of Obstetrics and Gynecology of the University of Vienna were investigated. The rate of Cesarean section showed during the last years a distinct increase (1969 to 1973: 16,6%, 1974 to 1977: 27,9%, 1977: 39,7%). A significant decrease of perinatal mortality in cases of breech presentation was not observed. On the other hand an increase in Cesarean sections diminishes the rate of perinatal mortality. In this publication the findings concerning the obstetrical results using abdominal or vaginal delivery are compared. No significant difference in perinatal mortality could be found. A better result could only be achieved in cases of mature infants. Our point of view is, that at present the indication of Cesarean section for cases of breech presentation should be very liberal. On the other hand vaginal delivery in some cases is still of importance.
