[Cesarean section of the second twin. Is this unusual mode of delivery justifiable?].

Within a ten-year period 1983-1992 eleven Caesarean sections were performed on the second twin after the first twin had been born vaginally. The reasons leading to this rather unusual mode of delivery are described here. Predominantly, multiple risk factors were present. One first twin and one second twin died in the early post natal period. In a comparative study of the literature, it is shown, that this, disputed mode of delivery has increased during the last twenty years and that, under special circumstances, it is a justifiable method of management of gemini deliveries.
