ObjectiveTo review a single-center case series of placenta percreta and to evaluate risk factors and the impact of surgical techniques used in previous cesarean delivery.MethodsThe present retrospective cohort study included pregnancies with placenta percreta managed between January 1, 2002, and March 31, 2017, at Saint Luc University Hospital, Brussels, Belgium. The data reviewed included demographics, outcomes, inter-pregnancy interval, and surgical techniques used for uterine closure in previous cesarean delivery. A cases series of non-accreta placenta previa was used as a control group.ResultsThere were 19 pregnancies included in the study. The most common ultrasonography signs in the study group were loss of the clear zone (14/17; 82%), placental lacunae (17/17; 100%), and subplacental hypervascularity (11/14; 79%). Median gravidity, parity, and number of previous cesarean deliveries were higher (P<0.05) and inter-pregnancy interval was longer (P<0.05) in the study group than the control group. There was no difference between the groups in the surgical techniques used for previous cesarean deliveries.ConclusionThe prenatal ultrasonography diagnosis of placenta percreta is accurate and facilitates optimal management by a specialized multidisciplinary team. Multicenter studies are required to further evaluate the impact of the surgical techniques used for prior cesarean delivery on the risks of placenta percreta in subsequent pregnancies.© 2017 International Federation of Gynecology and Obstetrics.
