实时三维能量多普勒超声在凶险性前置胎盘产前诊断中的价值研究

Value of real-time 3D energy Doppler ultrasonography in prenatal diagnosis of pernicious placenta previa

目的探讨实时三维能量多普勒超声在凶险性前置胎盘(PPP)产前诊断中的价值。方法回顾性分析2019年1月至2020年12月该院收治的37例产后确诊为PPP孕妇的临床资料,以分娩情况及术后病理结果为“金标准”,对比常规彩色多普勒超声(彩超)与实时三维能量多普勒超声检查在PPP产前诊断中的价值。结果常规彩超检查诊断PPP符合率为89.2%(33/37),实时三维能量多普勒超声检查诊断PPP符合率为94.6%(35/37),二者诊断PPP符合率比较,差异无统计学意义(P>0.05);常规彩超检查诊断PPP合并胎盘植入符合率为65.0%(13/20),实时三维能量多普勒超声诊断PPP合并胎盘植入符合率为95.0%(19/20),二者诊断PPP合并胎盘植入符合率比较,差异有统计学意义(P<0.05)。结论实时三维能量多普勒超声检查能真实显示PPP合并胎盘植入部位的低速血流情况,对PPP合并胎盘植入的产前诊断具有重要价值。

Objective To investigate the value of real-time 3D energy Doppler ultrasound in the diagnosis of pernicious placenta previa(PPP).Methods The data of 37 pregnant women with definitely diagnosed PPP after delivery treated in this hospital from January 2019 to December 2020 were retrospectively analyzed.With the delivery situation and postoperative pathological results as the gold standard,the values of PPP prenatal diagnosis were compared between conventional color ultrasound and real-time three-dimensional energy Doppler ultrasound.Results The coincidence rate of conventional color ultrasound for diagnosing PPP was 89.2%(33/37),which of real-time 3D energy Doppler ultrasound was 94.6%(35/37).There was no statistically significant difference in the diagnostic coincidence rate between the two methods(P>0.05).The coincidence rate of conventional color ultrasound in the diagnosis of PPP complicating placenta implantation was 65.0%(13/20),which of real-time 3D energy Doppler ultrasound was 95.0%(19/20),and there was the statistically significant difference in the diagnosis coincidence rate of PPP complicating placenta implantation between the two methods(P<0.05).Conclusion Real-time 3D energy Doppler ultrasound can really display the low speed blood flow situation in the placenta previa site,and has the great value for the prenatal diagnosis of PPP complicating placenta implantation.
