Risk factors for operative vaginal delivery after a previous instrumental delivery.

Objectives: The aim of the present study was to assess factors associated with a repeat operative vaginal delivery (OVD) in women with a previous history of OVD.

Methods: A single-centre retrospective observational study was performed in the maternity ward of the Angers University Hospital between 20/09/2010 and 01/04/2021. All the patients who underwent an OVD between 01/09/2010 and 31/10/2013 (delivery n°1, n = 1215) and who subsequently delivered up to the 01/04/2021 (delivery n°2, n = 652) were included.
