[目的]探讨彩色多普勒超声在儿童先天性肝外门体静脉分流(CEPS)中的诊断价值.[方法]回顾性分析经超声诊断并经多螺旋CT或外科手术证实的 7 例CEPS患儿的超声声像特征.[结果]7 例患儿均经CT或外科手术证实,其中Ⅱ型 6 例,Ⅰb型 1 例,4例合并先天性心脏病.彩色多普勒超声能够敏感地发现异常血流并对血流方向、流速等指标进行测定,诊断准确率高,且结果与CT结果或手术所见相符.[结论]彩色多普勒超声作为一种快速、简单的检查手段,能清晰显示肝外门-体静脉分流之起源及走行,可作为CEPS检查的首选方法.“,”[Objective]To investigate the diagnostic value of color Doppler ultrasound in pediatric patients with congenital extra-hepatic portosystemic shunt(CEPS).[Methods]The ultrasonographic features of 7 chil-dren with CEPS diagnosed by ultrasound and confirmed by multi-helix CT or surgery were analyzed retrospec-tively.[Results]All the 7 cases were confirmed by CT or surgical operation were diagnosed as 6 cases with typeⅡ,1 case with type Ib and 4 cases with congenital heart disease.Color Doppler ultrasound can detect the ab-normal blood flow sensitively and determine the direction and velocity of blood flow.The diagnostic accuracy is high and the results are consistent with the results of CT or surgery.[Conclusion]As a rapid and simple meth-od,color Doppler ultrasound can clearly show the origin and route of extrahepatic portal-systemic venous shunt.It can be used as the first choice for CEPS.
