Evaluation of portal vein indices in cats with portosystemic shunts

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. The authors of this study used CT images to 1) compare the differences in PV-related indices between dogs and cats; 2) establish normal indices for cats; 3) compare the differences among three feline groups: cats without EHPSS, with asymptomatic EHPSS, and with symptomatic EHPSS; and 4) determine the usefulness of these indices for predicting symptomatic EHPSS in cats.
