A 4-month-old, female Maltese dog was referred with continuous heart murmur. Patent ductus arteriosus was diagnosed via radiography and echocardiography. The patient was untreated because of client’s refusal. After 13 months, the dog was referred again with seizure and salivation. Laboratory examination revealed increased liver enzymes, hyperammonemia and decreased total cholesterol and total protein. Microhepatica was identified on abdominal radiography. CT angiography showed a shunt vessel that originated from the portal trunk to the prehepatic caudal vena cava and patent ductus arteriosus connecting proximal descending aorta with the main pulmonary artery. No portal vasculature toward liver is observed after shunt vessel. The patient was diagnosed as concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia. In human, cardiac malformations are frequently observed in patients with congenital extrahepatic portosystemic shunt with portal vein aplasia. This report described concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia in a dog.
