Abnormal placentation – A survey of 173 cases

Aims: The purpose of this study was to identify incidence, risk factors and perinatal outcome of women with placenta accreata/increta/percreta (using the clinical and histological definition) and partial retention of the placenta. Methods: Case-controll study of 173 cases in a population of 7978 deliveries from 07/2000–06/2007. A multivariate analysis was performed. Results: The incidence of complete retention with a positive histology was 1.3%. Significant risk factors were: Previous caesarean section (O.R. 1.978, p=0.049), previous abortion (O.R. 1.758, p=0.025), previous retention of the placenta (O.R. 7.502,…
