The incidence of twin pregnancies has increased and currently accounts for 1.8% of all deliveries. 47.5% of twins are born prematurely (vs. 6% for singletons) of which 9.9% before 32SA. Caesarean section rates are also higher than for singletons (53.7% vs 19.2%) and 31.8% of caesarean sections are performed before delivery.

The optimal mode of delivery for preterm twins remains controversial. The latest recommendations for clinical practice emphasize that it is not appropriate to recommend one mode of delivery rather than another in the case of twin pregnancies at any term.

In view of all these elements, we wished to carry out a retrospective study at the Montpellier University Hospital in order to compare the neonatal outcome of preterms twins according to their mode of delivery : planned vaginal delivery versus planned cesarean delivery.
