Plain-English summary
An 18-month-old male Labrador retriever was brought to the vet because he had been experiencing chronic diarrhea and vomiting for two months. After some tests, the vet found that he had a rare condition called hepatic arteriovenous fistulae, which affects blood flow in the liver and can lead to serious complications. Although surgery was performed to address the issue, the dog continued to have problems with his portal vein and blood vessels, resulting in a cautious outlook for his recovery.

Abstract
An 18-month-old male Labrador retriever was referred for investigation of chronic intermittent diarrhoea and vomiting of two months duration. A diagnosis of hepatic arteriovenous fistulae was made. These are extremely rare hepatic vascular anomalies which confer arterial pressure to the portal vein. Liver atrophy, portal vein hypoplasia, portal hypertension and multiple acquired portosystemic collateral vessels are the main complications. Surgical excision is a challenge as resection of large lesions may be associated with significant blood loss. In this dog, persistence of portal vein hypoplasia and extensive collateral pathways following surgery led to a reserved prognosis.
