Aim: Placenta accreta spectrum (PAS) are major risk factor for obstetric hemorrhage, which is a major cause of fetomaternal mortality and morbidity especially in developing countries. It is aimed to investigate the characteristics, incidence, maternal and fetal outcomes of placenta previa cases with and without PAS. Additionally we intended to analyze the clinical features, risk factors of placenta previa cases presenting with PAS. Material and Methods: A retrospective cohort study was conducted to analyze the pregnancies of placenta previa with and without PAS. Written and electronic maternally-linked medical records between January 2005 and December 2014 were reviewed. Placenta previa diagnosis was confirmed ultrasonographically and PAS were defined clinically as placental adherence to the uterus without easy separation Results: A total of 11351 deliveries were analyzed between January 2005 and December 2014. 387 patients were diagnosed to have placenta previa. Multiple pregnancies were detected in 11 of 387 previa cases and those were excluded. The incidence of placenta previa was 3.41‰ in our institution. The number of gravida ≥4 increased the risk of PAS 1.56 folds, ≥2 previous cesarean section (C/S) 9.74 folds, ≥3 abortus 3.83 folds, gestational hypertension (GHT) by 29.72 folds and gestational diabetes (GDM) 2.49 folds. According to logistic regression analysis ≥3 abortus, ≥2 previous C/S, and GTH were statistically significant. Conclusion: Incases of placenta previa, ≥3 abortion, ≥2 previous C/S and GHT were the most important risk factors in terms of developing PAS. We should consider strict evaluation of placenta previa cases with these risk factors for PAS development during pregnancy may have a decreasing effect on maternal-neonatal morbidity and mortality.
