Liver Failure (Acute) in Dogs
Acute Hepatic Failure in Dogs
Acute hepatic failure is a condition characterized by the sudden loss of 70 percent or more of the liver's function due to sudden, massive, hepatic necrosis (tissue death in the liver).
Primary and secondary hepatobiliary disorders - those dealing with the liver, gallbladder, bile ducts or bile - are generally associated with variable hepatic necrosis. However, acute liver failure from severe hepatic necrosis is an uncommon phenomenon. Acute liver failure can affect the body through a number of system failures:
Acute liver failure is most often caused by infectious agents or toxins, poor flow of fluids into the liver and surrounding tissues (perfusion), hypoxia (inability to breathe), drugs or chemicals that are destructive to the liver (hepatotoxic), and excess exposure to heat. Necrosis (tissue death) sets in, with loss of liver enzymes and impaired liver function ultimately leading to complete organ failure.
Acute liver failure also occurs due to extensive metabolic disorders in protein synthesis (albumin, transport protein, procoagulant and anticoagulant protein factors), and glucose absorption, as well as abnormalities in the metabolic detoxification process. If this condition is not treated promptly, it can result in death.
Acute liver failure is diagnosed through a full blood workup (hematology), biochemistry analysis, urine analysis, biopsy (the removal and analysis of affected tissue), and ultrasound or radiology imaging.
