**1. Introduction**

Liver cirrhosis is the final stage of various chronic liver diseases. The concept is essentially morphological, defined as a diffuse alteration of hepatic architecture by the presence of necrosis, fibrosis and regenerative nodules. These disorders conduct to intrahepatic vascular changes and to the reduction of functional mass. Finally, the consequences are the development of portal hypertension and the occurrence of liver failure. (Ampurdanés S, 2002)

For many decades, alcohol was considered the leading cause of cirrhosis. But actually, viral hepatitis by viruses B (HBV) and C (HCV) are recognized as the most important sources. (Mandayam S) Another common cause is Nonalcoholic Fatty Liver Disease (NAFLD), followed by autoimmune diseases with or without cholestasis, among others.
