A 4 yr old spayed female mixed-breed dog presented with a 2 yr history of recurring increases in liver enzymes. Two congenital portosystemic shunts (PSSs) were identified using computed tomography (CT) angiography, which included a portoazygous and portorenal extrahepatic shunt. Double right renal veins were also identified. The shunts were successfully identified and attenuated with cellophane banding. Multiple congenital PSS is a rare phenomenon, but should be considered during exploratory laparotomy for PSS and in dogs with poor response to surgical attenuation of a single PSS. CT proved to be a crucial part of accurate diagnosis and surgical planning for this dog with multiple congenital PSS.
一只4岁已绝育的雌性混种犬，有2年肝酶反复升高的病史。通过计算机断层扫描（CT）血管造影术发现了两个先天性门体分流（PSS），其中包括一个奇静脉门体分流和一个肾外门肾分流。还发现了双右侧肾静脉。通过玻璃纸结扎成功识别并减轻了分流。多发性先天性PSS是一种罕见现象，但在对PSS进行剖腹探查时以及对单个PSS手术减轻效果不佳的犬只中应予以考虑。CT被证明是对这只患有多发性先天性PSS的犬进行准确诊断和手术规划的关键部分。
