The patient was non-clinical for PSVA, but her pre-anesthetic bloodwork was consistent with PSVA. On presentation to CUHA, the patient was bright, alert and responsive with normal general physical examination. Transcolonic nuclear scintigraphy and Computed Tomography with angiography were performed to diagnose portosystemic shunt. An exploratory laparotomy was performed to confirm multiple, acquired extrahepatic shunts secondary to portal hypertension. An ovariohysterectomy was performed after ensuring that the anomalous vessels were not associated with the reproductive tract. Surgical biopsies of the liver and small intestine were performed for histopathology which confirmed noncirrhotic portal hypertension and inflammatory bowel disease. Post-operative management entailed medical management for the hepatic and intestinal diseases with frequent visits to the primary care veterinarian and monitoring of alanine aminotransferase.DogsCongenital hepatic diseaseAtypical acquired Portosystemic shuntsPortal hypertensionCase Studiesdissertation or thesis
