Safe operative vaginal delivery requires a careful assessment of the clinical situation.~During the pushing efforts, the complexity of the delivery can lead to choose between an operative vaginal delivery attempt and a caesarean section straightaway. An emergency caesarean section for failed operative vaginal delivery is associated with a higher fetal and maternal morbidity, compared to a successful operative vaginal delivery and to a caesarean section straightaway.~The objective of this study was to develop a risk score of failed vacuum extraction leading to an emergency caesarean section.~This score could be an objective tool to help the obstetricians to choose between a vacuum extraction attempt and a caesarean section straightaway.~The investigators included patients who benefited from a vacuum extraction attempt in the Regional Teaching Hospital of Besançon (France) between January 2010 and December 2015. Patients were separated into two groups : the vacuum extraction failure group and the vacuum extraction success group.~The investigators selected maternal, fetal and labor characteristics which could influence success or failure of the vacuum extraction and compared them between the two groups.~The score was developed with the characteristics which significantly influence the vacuum extraction failure.
