摘要
目的探讨经静脉超声造影在诊断子宫剖宫产后瘢痕妊娠疑难病例中的应用价值。方法对常规超声显示孕囊与子宫剖宫产瘢痕关系密切,但不能做出明确鉴别诊断的24例患者行经静脉超声造影检查。根据最后的手术病理结果,比较常规超声及超声造影诊断的灵敏度、特异性、阳性预测值、阴性预测值、Youden指数及准确率。结果所有病例中,常规超声的诊断准确率为75.00%、灵敏度88.24%、特异性85.71%、阳性预测值93.75%、阴性预测值75.00%、Youden指数73.95%,而超声造影的诊断准确率为100%。超声造影修正常规超声诊断6例(25.00%),两种检查方法诊断准确率比较,差异有统计学意义(P<0.05)。结论超声造影能够提供更多、更准确的影像学信息,其诊断准确率高于常规超声,具有较好的临床价值。
Objective To explore the diagnostic values of contrast enhanced ultrasound(CEUS)on difficult cases of cesarean scar pregnancy.Methods CEUS was performed on 24 patients underwent ultrasound examination that revealed the relationship between gestational sac and cesarean scar was closed,but the images of US were atypical and the accurate differential diagnostic was hard to make.The diagnostic accuracy,sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV)and Youden index of conventional ultrasound and CEUS,according to the result of surgery and pathology were observed.Results The diagnostic accuracy of conventional ultrasound was 75.00%,Sensitivity was 88.24%,Specificity was 85.71%,PPV was 93.75%,NPV was 75.00%,Youden index was 73.95%,while the diagnostic accuracy of CEUS was 100%.CEUS corrected the diagnostic result of conventional ultrasound in 6 cases(25.00%).There was significantly difference of the diagnosis accurate rate between these two methods(P<0.05).Conclusion CEUS can provide more accurate diagnostic information.Its diagnostic accuracy is higher than that of conventional ultrasound,and it has great clinical value.
