Patients with decompensated cirrhosis are not necessarily life-threatening; decompensated cirrhosis is advanced cirrhosis. This kind of cirrhosis has a relatively short survival period of 5 years, usually 20%, so cirrhosis is a relatively difficult to treat and the mortality rate is relatively high, usually must be actively prevented. Cirrhosis can be caused by a variety of reasons, may be due to hepatitis B, hepatitis C or other drug hepatitis transformation, so we must pay attention to the cause of the examination. For example, patients with hepatitis B should use antiviral drugs for a long period of time, such as entecavir, lamivudine, telbivudine and so on. Usually must regularly check liver function, alpha-fetoprotein, liver imaging, if liver function abnormalities, also need to give liver protection drugs to protect the liver treatment.
