Abstract
Portosystemic shunt (PSS) was diagnosed in 43 dogs by mesenteric portogram from January, 2002 to June 2007 in Haemaru referral animal hospital. PSS was found in various breeds including Maltese, Miniature Schnauzer and Yorkshire Terrier and there was no predisposition in gender. In laboratory parameters, mean cell volume was lower than normal value in single shunt and alanine aminotransferase was higher than normal range in multiple shunts with clinical significance. Cystic calculi were found in over 50% dogs with PSS and even in 70.8% dogs with single shunt. In 81% dogs with PSS, extrahepatic single shunt such as portocarval type and portoazygous type was identified. Extrahepatic multiple shunt and intrahepatic single shunt were observed in 4 dogs, respectively. Gradual attenuation using ameroid constrictor was applied to 35 dogs with extrahepatic single shunt and the prognosis of these dogs were good except two dogs, which showed poor prognosis because of acquired multiple PSS and renal disease unrelated with PSS, respectively.
