Posterior placenta percreta: A rare case

Abstract

Background: Placenta accreta spectrum affects about 3 in 1000 pregnancies but the posterior accreta spectrum is a rare phenomenon with scarce literature available regarding risk factors. It is associated with delayed diagnosis and surgical complications. It is seen with lower number of prior caesarean deliveries relative to anterior location. Case Report: We hereby present a case of a 30-year-old Gravida 2 Para 1 Living 1 with previous 1 Caesarean section with 37-weeks 4 days gestation who was posted for repeat caesarean section in view of oligohydramnios with fetal growth restriction. Intra-operatively a posterior placenta precreta was diagnosed and a decision of hysterectomy was taken due to massive post-partum hemorrhage. The findings were confirmed on histopathological examination. Conclusion: Posterior placenta percreta is a rare phenomenon which leads to delayed diagnosis, surgical complications and increased morbidity and mortality. The risk factors and diagnostic guidelines have still not been established due to lack of available data. An adequate sample size will need to be studied to evaluate the etiopathology and diagnostic and treatment modalities to improve the maternal outcomes.
