[The development of children born by vaginal or abdominal breech delivery (author's transl)].

The early and late development of children born by the breech either by vaginal breech delivery or by caesarean Section is compared. The early and late morbidity of the two groups is discussed in detail. Considering the recently published data by Hagberg (6) theinterpretation of findings classified as secondary morbidity is very dificult. There are numerous especially antenatal factors which interfere with the interpretation. The conclusion is presented that it is a present not possible to make a definite statement on the value of vaginal or Caesarean Section delivery in breech presentation. It is still considered to be safe to do Caesarean Section delivery in breech presentation. It is still considered to be safe to do Caesarean Sections in breech presentations on an individualized basis.
