| 摘 要： | 目的对比CDFI和CEUS对肝移植术后早期及晚期肝动脉血栓(HAT)的诊断价值。方法收集CDFI或临床疑诊肝移植术后HAT患者64例,分为早期HAT(<30天)和晚期HAT(≥30天)。对所有患者均行CEUS检查,观察肝动脉有无血流显示及其走行;以CDFI测量血流峰值、收缩期加速度时间、阻力指数、有无湍流及其峰值。以DSA和(或)CTA+临床+超声随访为参考标准,计算CDFI和CEUS诊断早期、晚期HAT的敏感度、特异度和准确率。结果对早期HAT 18例,CDFI和CEUS诊断HAT的敏感度、特异度、准确率分别为100%(6/6)、83.33%(10/12)、88.89%(16/18)和100%(8/8)、100%(10/10)、100%(18/18);对晚期HAT 46例,CDFI和CEUS诊断HAT的敏感度、特异度、准确率分别为0、100%(36/36)、78.26%(36/46)和100%(9/9)、97.30%(36/37)、97.83%(45/46)。结论 CEUS能直观显示肝动脉走行,诊断肝移植术后HAT的准确率明显优于CDFI,尤其对早期HAT更具确诊价值。
