超声评分法联合增强型血流显示技术在凶险型 前置胎盘合并胎盘植入中的应用.

Objective　To analyze the application value of ultrasound scoring combined with enhanced flow in dangerous placenta previa（ PPP） combined with placenta accreta， in order to improve the ultrasonic diagnosis accuracy of PPP combined with placenta accreta. Methods　From January 2017 to June 2019，60 cases of pregnant and lying-in women with suspected PPP combined placental implantation in the Second People's Hospital of Yunnan Province were studied. Two-dimensional， ultrasound scoring and e-flow examination methods were routinely used in all pregnant women for the classification of PPP combined with placental implantation. Clinical surgery and pathological results were used as the gold standard for comparison， and the diagnostic efficacy of ultrasound scoring， e-flow and ultrasound scoring combined with e-flow for PPP combined with placental implantation was compared. Results　Among 60 pregnant women with suspected PPP combined with placental implantation， the sensitivity of ultrasound scoring combined with e-flow was higher than that of ultrasound scoring （P < 0.05） . The accuracy of ultrasonic scoring combined with E-flow was higher than that of ultrasonic scoring combined with e-flow （P < 0.05）. The diagnostic efficiency of ultrasound scoring combined with e-flow in PPP with placental implantation was higher than that of single ultrasound scoring or e-flow. Conclusion　Ultrasound scoring combined with E-flow has a higher diagnostic efficiency in the diagnosis of PPP combined with placental implantation. It is a combined examination method to promote the value and can provide guidance for clinical treatment. [ABSTRACT FROM AUTHOR]
