Portal vein 10mm alone cannot diagnose early cirrhosis, it should be combined with other manifestations and examination results of the patient. Portal vein internal diameter is one of the indicators for analyzing the pathogenesis of portal hypertension and liver function, and the normal value of portal vein internal diameter is usually 6-10mm, so when only the value of portal vein internal diameter of 10mm is obtained, cirrhosis can not be diagnosed in general, and it is necessary to diagnose it together with other test results. In the case of portal hypertension, which causes the inner diameter of the portal vein to widen to more than 10mm or the value to widen exponentially, it can be considered whether it is a simple physiological widening or the presence of liver diseases such as liver viral infections, hepatic schistosomiasis, cirrhosis, and other liver diseases. The specific diagnosis should be combined with other manifestations of liver disease to make a comprehensive judgment before taking therapeutic measures. If the portal vein is physiologically widened, no special treatment is needed. If the portal vein internal diameter is widened due to cirrhosis or other causes, treatment should be based on the cause of the disease. In order to avoid the occurrence of cirrhosis, it is recommended to go to the hospital for regular checkups, and primary diseases need to be treated in time to prevent further deterioration of the disease. In daily life, you should quit drinking, eat reasonably, pay attention to rest, avoid staying up late. Medications should be taken under the guidance of a physician, do not take medication on your own.
