【摘要】：目的:探讨完全性前置胎盘伴植入的彩超和核磁共振影像学特点,对比分析二者诊断胎盘植入的价值。方法:回顾性分析完全性前置胎盘怀疑伴胎盘植入患者33例,同时行彩色多普勒超声和核磁共振成像(MRI)检查,分析33例产妇彩超及MRI影像学资料特征,并与手术和(或)临床综合诊断结果比较,分析二者诊断胎盘植入的敏感性、特异性和准确性。结果:彩超和MRI对胎盘植入的诊断与手术或病理诊断金标准相比,Kappa值分别为0.687和0.680,两者与金标准有一致性。两种诊断方法比较Kappa值为0.79,诊断符合率一致(P0.01)。结论:彩超与核磁共振在产前诊断胎盘植入的准确性高,均可作为产前诊断的方法之一。
[Abstract]:Objective: To investigate the characteristics of ultrasonography and magnetic resonance imaging of complete placenta previa with implantation, compared the two diagnosis of placenta accreta. Methods: a retrospective analysis of complete placenta previa with suspected placenta implantation in 33 patients, at the same time by color Doppler ultrasound and magnetic resonance imaging (MRI) examination, analysis of 33 cases color Doppler ultrasound and MRI imaging features, and (or) compared with surgical and clinical comprehensive diagnosis results, the sensitivity analysis of the two diagnosis of placenta accreta, specificity and accuracy. Results: the color Doppler ultrasound and MRI of placenta implantation diagnosis and surgery or pathological diagnosis compared to the gold standard, the Kappa values were 0.687 and 0.680, two consistent with the gold standard. Two kinds of diagnostic methods are Kappa 0.79, the coincidence rate of diagnosis is consistent (P0.01). Conclusion: Color Doppler ultrasonography and MRI in the accuracy of prenatal diagnosis of placenta accreta were high, can be used for prenatal diagnosis One of the methods.

【正文快照】： 随着人流次数及剖宫产比例增加,完全性前置胎盘伴粘连、植入,尤其是疤痕子宫合并前置胎盘即凶险型前置胎盘日益成为产科的难治疾病之一。前置胎盘伴粘连、植入常导致难治性产后出血、休克、弥漫性血管内凝血(DIC),是孕产妇死亡的重要原因[1-2]。但胎盘粘连或植入产前诊断极其
