The portal vein, short for portal vein, is a major blood vessel in the liver that functions to collect venous blood from organs including the stomach, intestines, and spleen. Nutrients from digested food must flow through the portal vein into the liver for detoxification, synthesis, and decomposition before they can be used by the body. When there is a lesion in the liver or portal vein, the portal vein resistance increases and the pressure increases, resulting in portal hypertension, which causes symptoms such as splenomegaly, ascites, and vomiting of blood. The reason why portal hypertension is treated clinically as a special disease is that there are many causes of portal hypertension, and so far, no single method can solve all the problems. I personally believe that portal hypertension must be treated individually, using minimally invasive methods to reduce the invasion and blow to patients as much as possible, and our experience shows that minimally invasive individualized treatment has more advantages than traditional dissection, and ten years follow-up patients have obtained a much better prognosis.
