One patient had a cranial mesenteric artery-to-mesenteric vein fistula with multiple acquired extrahepatic portosystemic shunts. The second patient had both cranial and caudal mesenteric artery-to-mesenteric vein fistulas and multiple acquired extrahepatic portosystemic shunts.<\/jats:p>\n<jats:p><jats:bold>TREATMENT AND OUTCOME<\/jats:bold> Both patients underwent minimally invasive coil embolization of the mesenteric arterioportal fistulas, with complete occlusion confirmed by means of angiography at procedure completion. Clinical outcome approximately 1 year after treatment was assessed as fair to good because of recurrence of clinical signs that required medical management in 1 dog and some persistent serum biochemical abnormalities.<\/jats:p>\n<jats:p><jats:bold>CLINICAL RELEVANCE<\/jats:bold> Outcome for the 2 patients described suggested that coil embolization may be a feasible and effective minimally invasive technique for the treatment of mesenteric arterioportal fistulas in dogs. However, further investigation of the potential for chronic hepatic disease in patients with a history of acquired portosystemic shunts is warranted.<\/jats:p>","DOI":"10.2460\/javma.251.11.1306","type":"journal-article","created":{"date-parts":[[2017,11,20]],"date-time":"2017-11-20T15:57:43Z","timestamp":1511193463000},"page":"1306-1312","source":"Crossref","is-referenced-by-count":7,"title":["Minimally
