Survival time after portal vein shunt surgery needs to be judged according to the condition, treatment method, etc. Individual variability is relatively large and needs to be analyzed specifically. Portal vein hypertension surgery is a minimally invasive procedure that reduces the pressure in the portal vein and treats portal hypertension to reduce the risk of complications such as ascites, gastrointestinal bleeding, and portal vein thrombosis. After portal shunt surgery, it is necessary to continue to treat the primary disease to control the progression of the disease and to protect liver function. If the cirrhosis of the liver is stable and has not progressed any further, it does not affect life expectancy. However, if there is no further control of the primary disease after the operation and it continues to cause other complications, life expectancy will be affected. Therefore, it is still necessary to go to the hospital for regular checkups after portal shunt surgery to prevent further progression of the disease and to ensure the survival period.
