The normal value of portal pressure is 1.27-2.36 kPa. If the portal pressure exceeds 2.36 kPa, it is considered to be a manifestation of portal hypertension. Portal hypertension is commonly seen in middle-aged men and may be caused by capillary hemangioma, portal cavernous hemangioma, non-hepatopathic splenomegaly, thrombosis, increased venous pressure, various intrahepatic lesions, constrictive pericarditis, chronic right heart failure, tricuspid valve insufficiency, and may present with symptoms such as splenomegaly, ascites, vomiting of blood, and varicose veins of the abdominal wall, and in severe cases, lead to splenomegaly, vascularization, and hepatic pathology and even gastrointestinal bleeding, which can be life-threatening. You can go to the hospital for blood test, urine test to determine the cause of the disease, according to the clinical manifestations combined with ultrasound, X-ray to determine the use of methods to reduce the pressure of portal varicose veins, and if necessary, surgical treatment. Patients should pay attention to regular diet, chewing and swallowing slowly to avoid damage to the esophagus causing bleeding.
