Plain-English summary
Two cats were brought in with large amounts of fluid in their bellies, which was suspected to be due to high blood pressure in the portal vein (portal hypertension). A special type of scan (CT) showed that both cats had an unusual connection between an artery and the portal vein outside the liver, leading to a diagnosis of extrahepatic arterioportal fistula. This condition is rare in cats, and this is the first time it has been reported. The specific treatment for these cases wasn't detailed, but understanding the diagnosis is crucial for managing their health.

Abstract
Two cats presented with large volume ascites and the cause was suspected to be portal hypertension. On contrast CT they both showed enhancement of the main portal vein during the arterial phase and an anomalous connection between the celiac artery and extrahepatic portal vasculature, prompting a diagnosis of extrahepatic arterioportal fistula. An extrahepatic arterioportal fistula is a connection between any artery and the portal vein outside the liver and, to our knowledge, this is the first report in cats.
