Abstract
Occipito-posterior persistent presentation is a relatively rare obstetrical condition, occurring in 2 to 4.5% of deliveries. Failure of the occiput to spontaneously rotate has been associated with increased maternal and neonatal morbidity. We performed a retrospective study of 210 vaginal occiput posterior deliveries to investigate the influence of this position on maternal and fetal morbidity. Our results demonstrate that overall prognosis of occipito-posterior persistent presentation is good but less auspicious than occipito-anterior presentation on account of importance of perineal injuries and maternal and fetal infections. Forceps extraction in posterior presentation is criticized today. In our opinion, the vacuum extractor is the better instrument because it is less aggressive to maternal tissues and also because, in most cases, the fetal head rotates anteriorly after provoked flexion.
