摘要
目的探讨彩色多普勒超声在产前诊断凶险性前置胎盘合并胎盘植入中的准确性及临床应用价值。方法选取2018年1月至2020年6月我院产科收治的90例凶险性前置胎盘孕妇,均实施经腹部彩色多普勒超声、经阴道彩色多普勒超声、磁共振成像(MRI)检查,比较上述三种检查方法的诊断结果。结果参照病理学诊断结果,经阴道彩色多普勒超声与MRI对凶险性前置胎盘合并胎盘植入的诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于经腹部彩色多普勒超声(P<0.05)。经阴道彩色多普勒超声与MRI对粘连性胎盘植入、植入性胎盘植入的诊断符合率均高于经腹部彩色多普勒超声(P<0.05)。结论经阴道彩色多普勒超声对产前凶险性前置胎盘孕妇的胎盘植入可进行灵敏、准确地诊断。
Objective To investigate the accuracy and clinical application value of color Doppler ultrasound in prenatal diagnosis of dangerous placenta previa complicated with placenta implantation.Methods A total of 90 pregnant women with dangerous placenta previa admitted in the obstetrics department of our hospital from January 2018 to June 2020 were selected and examined by transabdominal color Doppler ultrasound,transvaginal color Doppler ultrasound and magnetic resonance imaging(MRI),and the diagnosis results of the above three examination methods were compared.Results According to the pathological diagnosis results,the diagnostic sensitivity,specificity,accuracy,positive predictive value and negative predictive value of transvaginal color Doppler ultrasound and MRI for dangerous placenta previa with placenta implantation were higher than those of transabdominal color Doppler ultrasound(P<0.05).The diagnostic coincidence rates of transvaginal color Doppler ultrasound and MRI for adhesive placenta implantation and implantable placenta implantation were higher than those of transabdominal color Doppler ultrasound(P<0.05).Conclusion Transvaginal color Doppler ultrasound can make sensitive and accurate diagnosis for placenta implantation in prenatal women with dangerous placenta previa.
