Abstract

Importance: The portal vein to aorta (PV/Ao) ratio is used to assess the clinical significance of extrahepatic portosystemic shunt (EHPSS). Previous studies using computed tomography (CT) were conducted in dogs but not in cats.

Objective: This study aimed to establish normal reference values for PV indices (PV/Ao ratio and PV diameter) in cats and determine the usefulness of these for predicting symptomatic EHPSS.

Methods: This study included 95 dogs and 114 cats that underwent abdominal CT. The canine normal (CN) group included dogs without EHPSS. The cats were classified into feline normal (FN, 88/114), feline asymptomatic (FA, 16/114), and feline symptomatic (FS, 10/114) groups. The PV and Ao diameters were measured in axial cross-sections.

Results: The group FN had a higher PV/Ao ratio than the group CN (p < 0.001). Within the feline groups, the PV indices were in the order FN > FA > FS (both p < 0.001). The mean PV diameter and PV/Ao ratio for group FN were 5.23 ± 0.77 mm and 1.46 ± 0.19, respectively. The cutoff values between groups FN and FS were 4.115 mm for PV diameter (sensitivity, 100%; specificity, 97.7%) and 1.170 for PV/Ao ratio (90%, 92.1%). The cutoff values between group FA and FS were 3.835 mm (90%, 93.8%) and 1.010 (70%, 100%), respectively.

Conclusions and relevance: The results demonstrated significant differences in PV indices between dogs and cats. In cats, the PV/Ao ratio demonstrated high diagnostic performance for symptomatic EHPSS. The PV diameter also performed well, in contrast to dogs.

对患有肝外门静脉分流猫的门静脉指数进行计算机断层扫描评估。

重要性：门静脉与主动脉（PV/Ao）比值用于评估肝外门静脉分流（EHPSS）的临床意义。以前使用计算机断层扫描（CT）进行的研究都是在狗身上进行的，但没有在猫身上进行过：本研究旨在确定猫的肝门静脉指数（PV/Ao 比值和 PV 直径）的正常参考值，并确定这些指数对预测无症状 EHPSS 的有用性：这项研究包括 95 只接受腹部 CT 检查的狗和 114 只猫。犬正常（CN）组包括无 EHPSS 的犬。猫被分为猫正常组（FN，88/114）、猫无症状组（FA，16/114）和猫有症状组（FS，10/114）。在轴向横截面上测量了 PV 和 Ao 的直径：结果：FN 组的 PV/Ao 比值高于 CN 组（P < 0.001）。在猫科动物组中，PV 指数依次为 FN > FA > FS（均 p < 0.001）。FN 组的平均 PV 直径和 PV/Ao 比率分别为 5.23 ± 0.77 mm 和 1.46 ± 0.19。FN 组和 FS 组之间的临界值分别为 PV 直径 4.115 毫米（敏感性 100%；特异性 97.7%）和 PV/Ao 比值 1.170（90%，92.1%）。FA组和FS组之间的临界值分别为3.835毫米（90%，93.8%）和1.010（70%，100%）：结果表明，狗和猫的 PV 指数存在明显差异。在猫中，PV/Ao 比值对有症状的 EHPSS 具有很高的诊断性能。PV 直径的表现也很好，这与狗的情况相反。
