Results and Conclusion: Pregnant women aged ≥35 accounted for the highest 45.5%. Women with a history of one-time cesarean section  accounted for  45%. The rate of placenta previa partial and placenta previa total is 45,5%. Color Doppler ultrasonography in the diagnosis of placenta accreta spectrum has sensitivity 77,8% specificity 85,71%.
