Conclusion
We found no large randomized controlled studies addressing
the optimal mode of delivery in women delivering a fetus in breech
presentation preterm. The available cohort studies indicate that CS
reduces neonatal mortality by 37% as compared to VD in preterm
breech delivery. This conclusion should carefully be interpreted,
concerning the lack of intention to treat analysis and other bias
that is inevitable in cohort studies. We have, however, summarized
the best available data on the subject. Further studies are
necessary, but a large randomized controlled trial is unlikely to
be performed in the near future.
