Cirrhosis is the caina end stage of the chronic hepatic injury caused by the infection, hepatotoxins copper and anticonvulsantsimmunologic injury chronic hepatitischronic cholestasis, fanina hypoxia [ 9 ].
Liver Biopsy and Histopathological Examination Liver biopsy is often required to definitely characterize the nature and severity of the hepatic disease. Despite ascitix advent of newer laboratory tests, imaging techniques, and ultrasound-directed fine-needle biopsy or aspiration, laparoscopy remains a valuable tool when appropriately applied in a diagnostic plan.
Resolution of skin lesions and long-term survival in a dog with superficial necrolytic dermatitis and liver cirrhosis. Dose, duration of exposure, and chemical composition of the agent contribute to how asitis is expressed by the host.
For this reason, a battery of tests must be used to diagnose the hepatobiliary affections.

Histopathological Features Diffuse hepatic necrosis is the primary histologic lesion asxitis consistently associated with acute hepatic failure [ 8 ]. Noncirrhotic Portal Hypertension Three unusual diseases of primarily young dogs, that is, acitis fibrosis, idiopathic hepatic fibrosis, and primary hypoplasia of portal vein might be grouped under this title. Ultrasonographic Features Sonographic features in cases of cirrhosis vary from multiple hepatic nodules from macronodular regeneration besides hyperechoic hepatic parenchyma and decreased liver lobe size [ 12 ] to diffuse hyperechoic bright but small liver with distended gall bladder and irregular contour [ 1314 ].
Effective Management Practices to Reduce Radiographic Features Radiographic appearance of cirrhosed liver varies with the stage and severity of the disease and a small, dense liver with an irregular nodular surface may be identified with or without pneumoperitoneograph most commonly in cirrhosis [ 7 ]. The liver plays a central role in the coagulation and fibrinolytic systems, and subtle abnormalities may be detected by assay of individual factor activities.
The clinicopathologic test results are typical of mild, moderate, or severe hepatocellular damage, suggested by high-serum ALT activity and variable increases in ALP activity [ 8 ]. Radiographic and ultrasonographic diagnosis of liver diseases in dogs and cats. National Center for Biotechnology InformationU. It is difficult fanina evaluate the entire liver as much of the liver is silhouetted by the diaphragm, stomach and right kidney [ 5 ].
