Buga syndrome is a group of diseases characterized by obstruction of the hepatic and inferior vena cava veins, leading to portal hypertension and impaired inferior vena cava reflux. Clinical symptoms may include enlarged liver and spleen, ascites, varicose veins in the esophagogastric fundus, as well as lower limb edema, hyperpigmentation, lower limb ulcers and other symptoms. In daily life, attention should be paid to a reasonable diet and adequate nutrition, and care should be taken to avoid excessive activity and overwork, which may lead to liver function damage. The prognosis of Buga syndrome is poor. Therefore, patients should go to the hospital for examination and treatment in time, and choose the appropriate treatment method under the guidance of doctors. At the same time, patients who have not been hospitalized for treatment should also be vigilant and pay attention to observe their own situation.
