Abstract：Objective：Toinvestigatethecharacteristicsofroutineultrasoundperformanceinchildren with biliaryatresia （BA）and to improve the accuracy of ultrasound diagnosis of BA.Methods ：A retrospective analysis of ultrasound findings in 32children with BA was conducted，and theresults werecompared with surgical explorationand pathology. Results：Theroutine ultrasound imagesof the 32children withBA included thefollowingfindings：（1）Additionally，the triangularcord sign（TC）wasobserved in the hilarregionin9cases.（2）32casesof abnormal gallbladdermanifestations， of which5were missinggallbladder，and27casesof abnormal gallbladdercontraction（22casesofcombinedwith small gallladderdeflationand/orstiffandthickenedcystwall）.（3）Hepatoportalcystswere presentin1case.（4）Subpericardial blood flow was positive in 4 cases. （5） Hepatic artery widening wasdetected in5cases.（6）Hepatic hilar lymph node enlargement was foundin1case.（7）Liver enlargement was observed in11cases，spleen enlargement was notedinlcase.
