Left liver atrophy after cure of hepatitis A. First of all, it is necessary to clarify whether the etiology of liver atrophy is caused by hepatitis A. After identifying the etiology of the liver atrophy, the cause of the liver atrophy will be treated according to the cause. Generally speaking, 85% of patients with hepatitis A fully recovered from clinical manifestations and biochemical indexes within 2-3 months, and almost all of them fully recovered by 6 months.HAV infection will not become a chronic disease, and patients with hepatitis A will not be re-infected after cured of the infection, but hepatitis recurrence may occur. Liver atrophy is now generally referred to as liver failure, and the term “liver atrophy” is rarely used in clinical practice. The incidence of fulminant hepatic failure is less than 1% in the course of hepatitis A. Fulminant hepatic failure, which is characterized by severe acute liver injury with encephalopathy and impaired synthetic function, occurs most often in patients over 50 years of age and in patients with other liver diseases such as hepatitis B or C. The treatment should be generalized to treat fulminant hepatic failure. For treatment, patients with fulminant liver failure should generally be referred to a treatment center capable of performing liver transplantation.
