CLD/Cirrhosis - CLD/Cirrhosis - DefinitionDefinition
The word cirrhosis, derived from the Greek term The word cirrhosis, derived from the Greek term ‘‘kirrhos,’’ refers to a diffuse process in the liver ‘‘kirrhos,’’ refers to a diffuse process in the liver characterized by the development of extensive characterized by the development of extensive fibrosis and replacement of the normal hepatic fibrosis and replacement of the normal hepatic architecture by structurally abnormal nodules of architecture by structurally abnormal nodules of fibrotic tissue. fibrotic tissue.
This structural change in the hepatic architecture This structural change in the hepatic architecture eventually leads to functional changes that are eventually leads to functional changes that are characterized collectively as the syndrome of characterized collectively as the syndrome of chronic liver failure (CLF). chronic liver failure (CLF).
Presence of these changes for more than 6 months Presence of these changes for more than 6 months distinguishes CLF from acute liver failuredistinguishes CLF from acute liver failure
