A 5-month-old intact male Shiba Inu was presented with a history of neurological symptoms after meals. Based on medical history and clinicopathological findings, it was suspected that the patient had a portosystemic shunt (PSS). Computed tomography (CT) showed that the patient’s abdominal organs were reversed from left to right. The patient had PSS in addition to segmental aplasia of the caudal vena cava (CVC) with azygos continuation. Heterotaxy was diagnosed. Surgical treatment was performed by gradual shunt vessel ligation. The patient progressed well for 19 months after the first surgery, and the clinicopathological findings were normal and were maintained. This is a rare case report of a PSS with heterotaxy and segmental aplasia of CVC with azygos continuation treated surgically in a dog.
