Background: A severe maternal complication known as placenta accreta, also known as an abnormally invasive placenta (AIP), carries a significant risk of substantial haemorrhage, peripartum hysterectomy, and potentially difficult surgery. This study aimed to focus on association of incidence of invasive placentation with previous deliveries circumstances. Patients and method: This Cross-sectional prospective the Faculty of Medicine at Zagazig University, Department of Obstetrics and Gynecology, from March 2022 until September 2022. A total of 170 pregnant women of different gravidity and parity with documented ultrasound of abnormally invasive placenta were enrolled. Result: there was a statistically significant positive correlation between numbers the frequency of placenta and the number of prior caesarean sections (more than two prior caesarean sections) accrete. In addition, we reported that the incidence of placenta accrete statistically significant increased among women previously delivered in non-tertiary center. We proved that there was a statistically significant negative correlation between inter-pregnancy interval (less than 1.5 years) and incidence placenta accrete. Bladder damage, which occurred in 5.9% of intraoperative complications in our study, was the most common one. On the other side, wound infection was the most common postoperative complication by a percentage of 2.9%. Conclusion: Cesarean section without medical cause or on maternal request should be avoided as possible as it is proved to be the major risk factor of placenta accrete.
