Untreated hepatic hemangioma may cause physical discomfort and serious complications to the patient. Hepatic hemangioma is the most common benign tumor of the liver, which often occurs at the age of 30~50 years old and is more common in women. Hepatic hemangioma has no obvious symptoms, especially when it is small (<3cm). It is generally recommended that hepatic hemangioma <5cm and asymptomatic people can be closely followed up and observed. For those with hepatic hemangioma ≥5cm and symptoms, surgery is recommended to avoid serious consequences: 1. Somatic discomfort: The mass can be touched in the abdomen, abdominal distension and discomfort, nausea, vomiting, loss of appetite, lumbar discomfort, difficulty in swallowing, jaundice, splenomegaly and so on. 2.Serious complications: (1) Hemorrhage and rupture: intra-tumoral hemorrhage and rupture may occur when hepatic hemangioma grows up, which may cause shock and endanger life in serious cases. (2) Buga syndrome: giant hepatic hemangioma leads to occlusion of the adjacent inferior vena cava and hepatic vein and obstruction of venous return, which in turn leads to liver enlargement with pain, ascites, liver function abnormality and so on. (3) Kasabach-Merritt syndrome: after thrombus appears in the giant hepatic hemangioma, it causes thrombocytopenia, and coagulation abnormality occurs after a large amount of coagulation factors are consumed. Hepatic hemangioma is recommended to follow the doctor’s instructions for treatment to avoid serious consequences.
