Two calves and two foals presented with episodic clinical signs of diffuse central nervous system disease. Portosystemic anomalies were tentatively diagnosed based on the history, clinical signs and increased serum concentrations of blood ammonia and total serum bile acids with normal concentrations of liver derived enzymes. one calf died before intraoperative contrast portography, whereas the other calf and both foals had marked clinical improvement after intensive medical therapy. Surgical correction was attempted in these three animals and was successful in one foal. A right paracostal celiotomy was superior to a ventral median approach for exposure to the portal vascular system and shunt access.
两头犊牛和两匹小马驹出现了弥漫性中枢神经系统疾病的间歇性临床症状。根据病史、临床症状以及血氨和血清总胆汁酸浓度升高而肝脏衍生酶浓度正常，初步诊断为门体循环异常。一头犊牛在术中造影门静脉造影前死亡，而另一头犊牛和两匹小马驹在强化药物治疗后临床症状明显改善。对这三只动物尝试进行手术矫正，其中一匹小马驹手术成功。右侧肋旁剖腹术在暴露门静脉血管系统和分流通道方面优于腹正中入路。
