A Single Center Experience on the Management of Placental Invasion Abnormalities

Abstract

Objective: The aim of this study is to investigate our management of placental invasion abnormalities. Methods:A retrospective study was conducted on patients admitted to a tertiary referral center with a diagnosis of placental invasion abnormalities between 2011 and 2015. Risk factors and perinatal outcomes associated with placental invasion abnormalities were identified. Results:The overall incidence of placental invasion abnormalities during the 5-year period was 8.3/10000 deliveries, which showed an increasing trend. Ultrasonography and magnetic resonance imaging correctly identified placental invasion abnormality in 36.7% and 68.7% cases, respectively. Majority of patients (55.1%) with adherent placenta were diagnosed at the time of delivery. Of these patients, 22.4% underwent hysterectomy, 83.8% required at least one of the additional surgical procedures and 55% were transfused at least four units of packed red blood cell. Conclusion:Since placental invasion abnormalities are associated with significant morbidity, delivery should be scheduled in a tertiary center with appropriate expertise and facilities.
