Congenital portosystemic shunts were definitively diagnosed in 62 dogs over a period of 15 years. Maltese and Australian Cattle Dogs were significantly overrepresented, accounting for 14 and 13 cases, respectively. Maltese invariably had a single extrahepatic shunt derived from the left gastric or gastrosplenic vein, whereas Cattle Dogs usually had large intrahepatic shunts involving the right liver lobes. The clinical syndromes resulting from anomalous portosystemic communications were indistinguishable in the 2 breeds. Fasting blood ammonia concentration was elevated in 20 of 22 dogs tested, providing a minimally invasive and effective means of diagnosis. Complete or partial shunt attenuation was performed successfully in all 9 Maltese and in 2 of 6 Cattle Dogs in which it was attempted.
在15年的时间里，共确诊了62例犬先天性门体分流。马尔济斯犬和澳大利亚牧牛犬的比例明显过高，分别有14例和13例。马尔济斯犬总是有一个源于胃左静脉或胃脾静脉的单一肝外分流，而牧牛犬通常有涉及右肝叶的大型肝内分流。这两个品种因异常门体循环导致的临床综合征并无差异。在22只接受检测的犬中，有20只空腹血氨浓度升高，这提供了一种微创且有效的诊断方法。在所有9只马尔济斯犬以及6只尝试进行手术的牧牛犬中的2只中，成功进行了完全或部分分流减影术。
