摘　　要：目的探讨超声技术在凶险性前置胎盘中的诊断价值。方法选择凶险性前置胎盘患者73例,年龄24~37岁,平均年龄28.80岁。均给予超声、MRI检查,结合病理诊断结果,比较两种检查方式诊断凶险性前置胎盘的准确率及胎盘植入的效能。结果凶险性前置胎盘73例,其中胎盘植入44例。超声诊断凶险性前置胎盘的准确率为82.19%,与MRI检查(86.30%)比较,差异无统计学意义(P> 0.05);共有44例合并胎盘植入,胎盘植入发生率为60.27%;超声诊断凶险性前置胎盘合并胎盘植入的灵敏度、特异度、阳性预测值和阴性预测值低于MRI检查(72.73%vs 90.91%、66.67%vs 89.74%、71.11%vs 90.91%、68.42%vs 89.74%;P均> 0.05);胎盘植入患者胎盘后间隙全部或部分消失、胎盘附着处子宫肌层较薄、胎盘内旋涡流形成比例分别明显高于无胎盘植入患者(75.00%vs 20.51%、61.36%vs 23.08%、63.64%vs 25.64%;P=0.000、0.000、0.001)。结论超声在凶险性前置胎盘诊断中有较好的应用价值,值得临床使用。Objective To explore diagnostic value of ultrasound in sinister placenta previa. Methods A total of 73 patients with sinister placenta previa were enrolled, which aged 24-37 years old with mean age of 28.80 years old. All patients performed ultrasound and MRI, and the diagnosis accuracy of sinister placenta previa as well as effectiveness of placenta accreata were detected according to the results of pathological diagnosis. Results There were 73 cases of sinister placenta previa, 44 of whom had placenta implantation. There was no statistically significant difference in accuracy of ultrasound diagnosis of sinister placenta previa(82.19 %) and MRI(86.30 %)(P > 0.05);the incidence of 44 cases with placenta implantation was 60.27 %;The sensitivity, specificity, positive predictive value and negative predictive value of ultrasound in diagnosis of sinister placen-ta previa combined with placenta implantation were significantly lower than those of MRI(72.73 % vs 90.91 %, 66.67 % vs89.74 %, 71.11 % vs 90.91 %, 68.42 % vs 89.74 %;P > 0.05);In placenta implantation patients, the posterior placenta space disappears completely or partially, the myometrium at placenta attachment was significantly thinner and proportion of intrapla-cental vortex formation were significantly higher than those of non-placenta implantation patients(75.00 % vs 20.51 %, 61.36 %vs 23.08 %, 63.64 % vs 25.64 %;P = 0.000, 0.000, 0.001). Conclusion It is demonstrated that ultrasound shows good application value in diagnosis of sinister placenta previa, which is worthy of clinical application.
