Background: Antenatal diagnosis of placenta accreta spectrum should be set up for planning location, timing and specialized staffing delivery to decrease maternal mortality and morbidity rate
Purpose: Evaluation of Doppler ultrasound in prediction of the diagnosis of placenta accreta in cases of placenta previa with previous history of uterine surgery.
Patients and Methods:The study included 120 cases diagnosed as placenta previa (after 28 weeks of gestation) with previous uterine surgery.The diagnosis of placenta accreta was regarded as positive when any two of these color Doppler criteria is present:(1) Diffuse or focal lacunar flow pattern. (2) Hypervascularity of the uterine–bladder interface with abnormal blood vessels linking the placenta to the bladder. (3) Markedly dilated vessels over the peripheral subplacental region with turbulent flow typified by high velocity (peak systolic velocity >20 cm/s) and low resistance waveform.(4) Cervical hypervascularity.
Results: The color Doppler ultrasonography examined that the sonographic diagnostic sensitivity in detecting the placenta accreta was 87.0% and specificity was 93.0%.
Conclusion: Doppler ultrasound has diagnostic efficacy and clinical utility in prediction of the diagnosis of placenta accreta spectrum.
