摘　　要：目的　在婴儿期有多种引起黄疸的肝胆外科疾病,本研究通过术前对胆道闭锁、先天性胆总管囊肿等疾病声像图形态特点及血供的观察,探讨彩色多普勒超声显像在婴儿外科性黄疸鉴别诊断中的应用价值。方法　二维超声观察肝脏、胆囊及胆管的形态大小,彩色多普勒超声观察门静脉及肝动脉的血流并鉴别肝动脉及胆管结构。结果　手术治疗胆道闭锁 20 例,超声术前诊断18例;先天性胆总管囊肿16例,超声术前诊断16例。胆道闭锁术前超声显示肝脏肿大,胆囊细小且壁增厚,肝门部三角形高回声块,门静脉流速减慢,肝动脉流速增快,阻力指数增大。先天性胆总管囊肿超声显示胆总管部位囊性包块。结论　彩色多普勒超声对婴儿外科性黄疸常见病因的早期诊断、鉴别诊断与指导治疗均有重要的应用价值。Objective Surgical jaundice during infancy may be caused by different surgical conditions.The aim of this study was to assess the clinical value of color Doppler flow imaging (CDFI) in the pre-operative diagnosis of biliary atresia (BA) and choledocal cyst.Methods The morphology and size of liver, gallbladder and choledochal were observed by 2-D ultrasonography(US).CDFI for examing portal vein(PV) and hepatic artery(HPA).Results Twenty infants suspected of having biliary atresia and 16 infants with choledocal cyst were examined pre-operative.Diagnosis of BA and choledocal cyst was confirmed surgically and histologically.Small gallbladder,wall thickening and triangular cord sign were seen in BA . The velocity of PV was slow.The HPA appeared more prominent and the velocity was high .Conclusions It improves markedly the role of CDFI in the diagnosis, differentiation and opertive of different surgical jaundice.
