Congenital portosystemic shunts in foals are rare and only a small number of cases have been described. Detailed description of the course of the shunt is lacking in earlier reports. This is the first detailed description of a computed tomography angiography (CTA) displaying an extra-hepatic splenocaval shunt. A 1-month old colt showing increasing signs of dullness, ataxia, circling, lip-smacking and coordination problems was presented. Hyperammonemia was detected and abdominal CTA revealed an extra-hepatic portocaval shunt. During surgery, ligation of the abnormal vessel could not be achieved, and the foal was euthanized because of complications during surgery. CTA provided a detailed overview of portal vasculature. If a portosystemic shunt is suspected in a foal, CTA can be used to confirm the diagnosis and for surgical planning.
马驹先天性门体分流罕见，仅有少数病例被描述。早期报告缺乏对分流路径的详细描述。这是首次对显示肝外脾腔分流的计算机断层血管造影（CTA）进行详细描述。一匹1月龄的雄驹出现精神沉郁、共济失调、转圈、咂唇和协调障碍等症状加重。检测到高氨血症，腹部CTA显示肝外门腔分流。手术过程中，无法结扎异常血管，该马驹因手术并发症实施安乐死。CTA提供了门静脉系统的详细概况。如果怀疑马驹存在门体分流，CTA可用于确诊及手术规划。
