摘　　要：本研究探讨彩色多普勒超声血流显像(CDFI)诊断胆道闭锁(BA)患儿的临床应用价值。选取持续性黄疸且诊断为BA患儿68例作为BA组,选取同期64例健康新生儿作为对照组。两组研究对象均接受CDFI检查,分析超声特征变化。结果显示,BA组胆囊形态异常率89.71%,左右肝管超声显示率100.00%,肝外胆管超声显示率100.00%,均高于对照组(P<0.05);门静脉平均流速(Vpv)、门静脉前后径(Dha)、门静脉阻力指数(RIha)、脾静脉阻力指数(RIspa)诊断BA患儿的AUC值分别为0.899、0.774、0.731、0.648。CDFI作为无创手段诊断BA患儿具有较高的临床实用价值,根据胆囊形态、血流参数等指标进行综合判断价值较高。This study explored the clinical application value of color Doppler flow imaging(CDFI)in the diagnosis of biliary atresia(BA).Sixty-eight infants with persistent jaundice and biliary atresia were selected as BA group,and 64 healthy newborns during the same period were selected as the control group.CDFI examination was performed on both groups to analyze the changes in ultrasonic characteristics.The results showed that the abnormality rate of gallbladder morphology in the BA group was 89.71%,the ultrasound display rate of the left and right hepatic ducts in the BA group was 100.00%,and the extrahepatic bile duct ultrasound display rate in the BA group was 100.00%,which were all higher than that of the control group(P<0.05).The AUC values of mean portal velocity(Vpv),anteroposterior diameter of portal vein(Dha),portal vein resistance index(RIha)and splenic vein resistance index(RIspa)were 0.899,0.774,0.731 and 0.648,respectively.CDFI has high clinical practical value as a non-invasive method for diagnosing children with BA,and it is of high value to make comprehensive judgments based on the gallbladder morphology and blood flow parameters.
