Background Placenta accreta placenta is a condition in which placenta is adherent to the uterine wall because of myometrial invasion. Patients and methods In this prospective study, 60 pregnant women with placenta previa were enrolled at the Obstetrics Clinics of Menoufia University Hospitals in the period from January 2016 to December 2017. The placenta was scanned using gray-scale ultrasound and color Doppler. Placenta accreta index was formulated for each patient. Definitive diagnosis was made at delivery when the myometrium invasion by the placenta was seen. The hysterectomy specimens were sent for pathological confirmation of placental invasion. Data were collected and entered using Statistical Packages for the Social Science program for statistical analysis. Results Nineteen patients were found to have placenta accreta. All the parameters of placenta accreta index were statistically significant. The total score was significantly higher in accreta patients (P < 0.001). Receiver operating characteristic curve showed that score 4 was the best cut-off point to diagnose placenta accreta. The number of patients that had index above 4 was 18 patients. Seventeen patients of them were proved to have placenta accreta (P < 0.001). Conclusion Placenta accreta index score 4 can be used as a cut-off value for prediction of placental invasion in patients with placenta previa.
