Acute liver failure is difficult to cure. Acute liver failure is a short-term disease with massive necrosis of liver cells and severe impairment of liver function, accompanied by symptoms of coagulation disorders, ascites and hepatic encephalopathy, which is characterized by rapid progression of the disease and high mortality rate. Acute liver failure is difficult to be cured completely, if the condition permits, liver transplantation and artificial liver treatment can achieve a better effect, but after the liver transplantation surgery may have a series of complications, and the transplanted liver may have a certain degree of rejection of the body, so it is difficult to cure acute liver failure completely. Once acute liver failure is detected, it needs to be treated immediately to avoid delaying the condition.
