Usually, hepatitis progressing to cirrhosis will cause obstruction of portal venous return, resulting in venous stasis, splenomegaly and splenic portal vein widening, which can be improved after drug and surgical treatments. 1. If the cause of liver damage is treated, such as antiviral drugs such as lamivudine, abstaining from alcohol, and stopping the drugs currently used for liver damage, liver function can be restored to a certain extent, and the enlarged liver and spleen can be narrowed accordingly. 2. If the lesion is of long duration and improper treatment leads to ineffective recovery of liver function and evolves into cirrhosis, then surgical treatment such as appropriate drainage of ascites, weaning or shunt operation is recommended. When the pressure is lowered, the lumen of the portal vein can also be moderately constricted. Hepatitis causes impaired liver function, resulting in portal vein blood entering the liver is blocked, which leads to portal hypertension, causing splenomegaly and widening of the splenic vein, at this time the patient is recommended to go to a regular hospital in a timely manner for treatment, follow the doctor’s advice, so as not to delay the condition.
