Background: Massive obstetric hemorrhage is still one of the leading cause of pregnancy related death and placenta previa accreta remain one of the major predisposing factors. With the increasing rate of cesarean delivery the incidence of both placenta previa and accreta is steadily increase so we anticipate more cases of placenta previa accreta in our obstetric practice. Diagnosis can be achieved by ultrasound in the majority of cases. Aim of the study: To determine the accuracy of trans-abdominal Doppler U/S in diagnosing of placenta previa accreta in patients with previous cesarean sections and comparing with intraoperative finding Patient and Methods: The study included 80 pregnant women who had under gone previous cesarean section at Obstetrics and Gynecology department of Al-Yarmouk teaching hospital and were diagnosed to have partial or total placenta previa in the current pregnancy were subjected to trans-abdominal Doppler ultrasound examination after 28th week of gestation to determine the possibility of placenta accreta in comparison with intra operative finding. Results: The result of the 80 placenta previa cases, twenty-six women exhibited characteristic color Doppler imaging patterns highly specific for placenta accreta. One of them had false positive color Doppler imaging, and twenty-five confirmed at cesarean section to have placenta accreta. Of the 54 women with negative color Doppler imaging results, two of them had placenta accreta both of them were posterior placenta previa. The sensitivity of color Doppler imaging in the diagnosis of placenta previa accreta was 92.6%, specificity was 98.1%, the positive predictive value was 96.2% and negative predictive value was 96.3% Conclusion: Color Doppler U/S provides an opportunity for early and accurate diagnosis of placenta accreta
