摘要
目的:描述胆道闭锁患儿的肝脏的超声多普勒表现,与非胆道闭锁患儿和正常婴儿比较。方法:回顾性分析50例为非感染性胆汁淤积黄疸患儿和25例对照组正常患儿的超声及彩色多普勒表现。结果:50例患儿中20例被证实为胆道闭锁、30例为非胆道闭锁。肝门区纤维块诊断胆道闭锁的敏感性、特异性、阳性预测值、阴性预测值分别为60%、96%、92%、79%。肝包膜下血流的敏感性、特异性、阳性预测值、阴性预测值分别为95%、93%、91%、96%。胆道闭锁病人的肝动脉内径平均值为(2.1±0.2)mm,明显大于非胆道闭锁病人((1.2±0.2)mm,P<0.001)和对照组((1.2±0.1)mm,P<0.001)。在胆道闭锁的病人中,约90%患儿其γ-谷氨酰转肽酶大于800 IU/L。结论:彩色多普勒检查肝包膜下血流是除常规超声外的检出胆道闭锁的有效补充。通过彩色多普勒检查,我们能预防胆道闭锁的诊断延误。
Objectives： To describe color Doppler uhrasonographic （US） findings in livers of neonates with biliary atresia （BA） and to compare them with US findings in livers of neonates with non-BA and control subjects. Methods： US and color Doppler US findings were retrospectively reviewed in 50 patients with neonatal cholestasis and 25 control subjects. Results： BA and non-BA were confirmed in 20 and 30 patients, respectively. In the diagnosis of BA, sensitivity, specificity, positive predictive value and negative predictive value of the triangular cord sign （TC sign） on US images were 60%, 96%, 92% and 79%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of hepatic subcapsular flow on color Doppler US images were 95%, 93%, 91% and 96%, respectively. Mean diameter of the hepatic artery in pa- tients with BA （（2.1±0.2）ram） was significantly larger than that in patients with non-BA （（1.2±0.2）ram, P〈0.001） and control subjects（（1.2±0.1） ram, P〈0.001）. In patients with biliary atresia, about 90% of children with its 7-GGT〉800 IU/L. Conclusion： The detection of BA can be supplemented by performing color Doppler US in addition to routine US, when evaluating hepatic subcapsular flow by using color Doppler US, we can potentially prevent delayed diagnosis of BA.
