The important pathogenesis of hepatic encephalopathy is

The important pathogenesis of hepatic encephalopathy includes abnormal portal-systemic shunt, other metabolic abnormalities, severe liver function disorders, etc. The specific analysis is as follows:

1. Abnormal portal-systemic shunt

due to abnormal portal-systemic shunt causes part of portal vein blood to enter systemic circulation without passing through liver, which may be accompanied by abnormal liver function and hepatic encephalopathy.

2. Other metabolic abnormalities

Due to congenital urea cycle disorders, elevated blood ammonia will occur, affecting liver function and leading to hepatic encephalopathy.

3. Severe liver function disorders

Due to chronic hepatitis B and alcoholic liver disease, it is easy to cause severe liver function disorders, leading to central nervous system dysfunction and hepatic encephalopathy.
