Two dogs referred to Veterinary Medical Center, Chungbuk National University diagnosed as multiple extrahepatic portosystemic shunt were reported. The first dog was a 20-month-old, 8 kg, male Cocker spaniel with history of peritoneal effusion, diarrhea, anorexia and stunted growth. The second dog was a 3-year-old, 13.4 kg, male Jindo with a history of severe depression. Hematologic examination of first dog revealed mild microcytosis and nonregenerative anemia. All of 2 cases, serum chemical values showed increase of serum ammonia, ALP, r-GTP and glucose. In survey radiography, microhepatia was apparent. In the color Doppler ultrasonographic examination, the first dog revealed a dilated tortuous vein communicating with caudal vena cava was observed near the left kidney and the second dog revealed numerous shunting vessels ventral to L5 and L6. Transcolonic portal scintigraphy of the first dog confirmed the presence of portosystemic shunt. In intraoperative jejunoportography, the first dog showed single congenital extrahepatic portosystemic shunt and multiple acquired extrahepatic portosystemic shunts. The second dog showed multiple acquired extrahepatic portosystemic shunts. In these dogs, the presence of congenital and acquried portosystemic shunts and histopathologic findings were considered to represent a combination of multiple extrahepatic portosystemic shunts and noncirrhotic portal hypertension or portal vein hypoplasia.
