Abstract

A 3-year-old crossbreed dog (case 1) and a 3-month-old German Shorthaired Pointer (case 2) were presented for acute signs of encephalopathy. A portosystemic shunt (PSS) was suspected based on clinical context and laboratory exam results and was confirmed on computed tomography (CT) angiography in both cases. A left-sided azygos (case 1) and right-sided azygos (case 2) continuation of an interrupted caudal vena cava (CVC) and a situs ambiguous (SA) were also observed and considered as incidental findings. Both dogs underwent PSS surgical correction. Postsurgical follow-up imaging procedures suggested concomitant primary hypoplasia of the portal vein (PHPV) in both cases.

两只狗尾部腔静脉节段性发育不全、门-腔分流和坐骨不清的计算机断层扫描特征。

一只 3 岁大的杂交犬（病例 1）和一只 3 个月大的德国短毛猎犬（病例 2）因出现急性脑病症状而就诊。根据临床症状和实验室检查结果，怀疑是门静脉分流（PSS），两例病例均经计算机断层扫描（CT）血管造影证实。此外，还观察到左侧颧静脉（病例 1）和右侧颧静脉（病例 2）延续中断的尾腔静脉（CVC）以及坐位不清（SA），并将其视为偶然发现。两只狗都接受了 PSS 手术矫正。手术后的随访影像学检查显示，两例病例均伴有原发性门静脉发育不全（PHPV）。
