Abstract Objective: To evaluate the potential value of uterine arcuate artery blood-flow parameters in diagnosing placenta previa complicated with placenta accreta. Methods: 64 pregnant women in the third trimester with placenta previa who underwent ultrasound examination in the Third Affiliated Hospital of Zhengzhou University from January 2016 to January 2017 were adopted. All cases underwent uterine arcuate artery Doppler velocimetry to measure the peak systolic maximum velocity(PSV), resistance index(RI) and pulsatility index(PI). The patients were divided into two groups according to the operation results. Statistical analysis of PSV, RI and PI were performed to confirm the optimum boundary points of the indices. Results: The PSV of uterine arcuate artery was higher(P＜0.001) while RI and PI was lower(P=0.01, P=0.03) in the placenta accreta group compared to previa alone. The difference was statistically significant(P＜0.05). The diagnostic accuracy of PSV of uterine arcuate artery was high while RI and PI was moderate and the optimum boundary points was 39.33 cm/s, 0.385 and 0.51. Conclusion: The PSV, RI, PI of the uterine arcuate artery is of definite value in the diagnosis of placenta previa complicated with placenta accreta.
