【 摘 要 】

A retrospective study in 80 cases of canine hepatic cirrhosis was carried out at the Veterinary Pathology Laboratory of the Federal University of Santa Maria, Rio Grande do Sul, Brazil. Considering those cases in which the sex and age of the dogs were informed in the necropsy reports, males comprised 53.8% of the cases and 46.2% were females; while 50.0% of these dogs were aged, 48.6% were adults and 1.4% were puppies. The main observed clinical signs include ascites (39/80 [48.8%]), icterus (19/80 [23.8%]), anorexia (13/80 [16.2%]), neurological disturbances (12/80 [15.0%]), dyspnea (12/80 [15.0%]) and subcutaneous edema (10/80 [12.5%]). In 63 dogs for which there was a description of gross morphology in the necropsy reports, 76.2% had macronodular and 23.8% had micronodular cirrhosis. In 14 cases in which the histopathology of the liver was reviewed different degrees of fibrosis were observed: mild in 57.2%, moderate in 21.4%, or marked in 21.4%; in these cases there were no correlation with the degree of fibrosis and other associated histological changes such as lipidosis, biliary ducts hyperplasia, inflammation, bilestasis, hemosiderosis and random hepatocellular necrosis. Extra hepatic changes included ascites (39/63 [61.9%]), icterus (19/63 [30.2%]), status spongiosus (15/63 [23.8%]), hydrothorax (12/63 [19.0%]), subcutaneous edema (10/63 [15.9%]), portosystemic shunts (11/63 [17.5%]), gastric our duodenal ulceration (11/63 [17.5%]) and cholemic nephrosis (4/63 [6.3%]).
