Background: Portosystemic deviation (PSD) is a congenital or acquired vascular anomaly that allows an abnormal bloodflow from the portal vein directly to the systemic circulation. This liver by-pass avoids hepatic metabolism of severaltoxins. Congenital PSDs are usually solitary and extra-hepatic, with a high incidence in pure-breed dogs. Acquired PSDsare usually multiple and occur as a consequence of portal hypertension. Surgery is the definitive treatment. Cliniciansand surgeons may present difficulties in the propaedeutic of animals with PSD. This paper aims at reporting a successfulsurgical treatment of a solitary extra-hepatic congenital PSD in a mixed-breed dog.Case: A 7-month-old mixed-breed dog, female, spayed, weighing 8 kg, was presented with a history of sudden syncopeafter feeding. Complementary exams revealed normocytic hypochromic anaemia, hypoalbuminemia and increased alanineaminotransferase and alkaline phosphatase. Abdominal ultrasound revealed an anomalous vessel inserted in the caudalcava vein, compatible with a congenital extra-hepatic PSD. Computed tomography revealed the anomalous vessel, with1,1 cm of diameter, originated from the cranial mesenteric vein and it inserted in the cranial margin of the caudal cavavein. A medical support was started with hydration, metronidazole, lactulose, probiotic and Hepatic diet. After 15 days thedog was submitted to surgery and a 5 mm ameroid constrictor ring was placed to gradually close the anomalous vessel.The dog recovered well and an abdominal ultrasound was repeated after 30 days, showing the ameroid constrictor ringring in the left cranial abdominal region, occluding the PSD close to its insertion in the caudal cava vein...(AU)
