Based on medical records, dogs were assigned to disease categories: (1) liver disease; (2) non\u2010hepatic neoplasia; (3) pancreatitis; (4) infectious disease; (5) immune\u2010mediated disease; (6) other; (7) multiple diseases. Different categories were compared for the prevalence of portal vein thrombosis. Outcome was evaluated in dogs with and without portal vein thrombosis. Ultrasound reports were reviewed to determine the detection of thrombosis on ultrasound.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010eight dogs (13%) had portal vein thrombosis. The pancreatitis category contained the highest percentage of portal vein thrombosis among different categories (eight of 19; 42%). There was a similar outcome between dogs with and without portal vein thrombosis. Of 21 dogs with portal vein thrombosis that had ultrasound performed, ultrasound detected thrombosis in four of 21 (19%) cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Clinical Relevance<\/jats:title><jats:p>In this study, portal vein thrombosis prevalence was higher in dogs with pancreatitis compared to dogs with liver disease, non\u2010hepatic neoplasia and other abdominal or systemic disease. The portal system should be carefully evaluated with imaging in dogs with pancreatitis. As compared to ultrasound, CT angiography is the imaging method of choice for detection of portal vein thrombosis in dogs.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jsap.13315","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T13:15:47Z","timestamp":1615295747000},"page":"562-569","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Prevalence of portal vein thrombosis detected by computed tomography angiography in dogs"],"prefix":"10.1111","volume":"62","author":[{"given":"L.
