摘　　要：为评估先天性门体分流(CPSS)疾病对犬肝脏体积的影响及不同类型CPSS与犬肝脏体积的相关性,对来医院就诊的CPSS患犬病例进行回顾性分析。筛选出13例CPSS患犬病例,所有患犬均进行了腹部增强CT检查,记录CPSS类型,随机选取13条无肝脏相关疾病且肝脏影像正常的犬作为对照。使用定量CT技术在腹部增强CT延迟期所获得的多平面重建影像中的各个平面中渲染出肝脏影像,从而得到肝脏的容积重建影像,继而获得肝脏体积(V),记录每条犬肝脏体积(V)与体重(W)的比值(V/W)。结果:分别测得CPSS患犬平均V/W值为(18.57±4.52)cm^(3)/kg,对照组犬平均V/W值为(29.31±6.55)cm^(3)/kg,两者差异极显著(P<0.01);CPSS患犬中,肝内CPSS患犬平均V/W值为(23.50±5.90)cm^(3)/kg,肝外CPSS患犬平均V/W值为(17.09±2.99)cm^(3)/kg,两者差异显著(P<0.05)。以上结果表明,通过测量V/W值可对CPSS患犬肝脏进行评估,CPSS导致患犬肝脏体积显著减小,同时肝外CPSS对肝脏体积影响较肝内的影响更显著。To evaluate the effect of congenital portosystemic shunt(CPSS)on hepatic volume and the correlation between different types of CPSS and liver volume in dogs,a retrospective analysis was performed here on dogs with CPSS.Thirteen dogs with CPSS were selected and all of them underwent contrast-enhanced abdominal CT.CPSS types were accurately recorded in all dogs.Thirteen dogs without liver-related diseases and liver imaging abnormalities were randomly selected as control.The liver image was rendered on each plane of the CT multi-plan reconstruction images obtained in the delayed phase of abdominal contrast-enhanced CT.Then,the liver volume(V)was recorded through CT quantitative technology.The ratio(V/W)of hepatic volume(V)to body weight(W)of each dog was recorded,too.The results showed that the V/W ratio was(1857±452)cm^(3)/kg in the dogs with CPSS and(2931±655)cm^(3)/kg in the control group,and the difference was very significant(P<001).In the dogs with CPSS,the mean V/W was(2350±590)cm^(3)/kg in those with intrahepatic CPSS and(1709±299)cm^(3)/kg in those with extrahepatic CPSS,and the difference is significant(P<005).It was concluded that the liver of the dogs with CPSS could be evaluated by measuring their V/W value.CPSS caused a decrease in hepatic volume in dogs,and the effect of ex-trahepatic CPSS on hepatic volume was more significant than that of intrahepatic CPSS.
