The vast majority of hepatic hemangiomas are not serious. Because hepatic hemangiomas are benign tumors, they generally do not have a tendency to become malignant and grow relatively slowly on a daily basis. For some small hemangiomas, regular follow-up examinations are required, and hepatobiliary ultrasound is performed every six months to a year to assess the size and growth rate of the hepatic hemangioma. As long as the hepatic hemangioma does not increase significantly, or the overall size does not exceed 5 cm, no special treatment is needed. In addition, it may become relatively serious if rupture, excessive size or compression of organs occur.1. Rupture and bleeding of hepatic hemangioma: Spontaneous rupture of hemangioma is very rare, mainly seen after trauma, especially upper abdominal trauma, and some car accidents are common. This situation is very serious and needs to be treated by timely infusion, blood transfusion, or hemostasis surgery and arterial embolization. 2. Oversized hepatic hemangioma: Generally, if the hemangioma exceeds 10 cm or is located at the edge of the liver, it needs to be given treatment in time to avoid leading to adverse risks and symptoms, in addition, attention should also be paid to the possibility of the tumor being malignant. 3. Hemangioma compression: If the hemangioma in the left liver grows huge, it is easy to compress The growth of hemangioma in the left liver can easily compress the stomach, leading to abnormal eating, bloating, indigestion and other uncomfortable symptoms. Some hepatic hemangiomas may compress the lungs upward, leading to shortness of breath, difficulty in breathing and other uncomfortable symptoms. Other hepatic hemangiomas may compress the vena cava or hepatic vein, resulting in narrowing, occlusion, and obstruction of return flow, resulting in hepatomegaly, pain, ascites, and other serious symptoms. Some hepatic hemangiomas may compress the bile ducts and cause jaundice and poor bile excretion. These conditions are more serious and require prompt and appropriate treatment, including medication or surgery. However, in general, these adverse symptoms of hepatic hemangioma are relatively serious, but the probability of occurrence is not high. The vast majority of hemangiomas are relatively small and relatively speaking, hepatic hemangioma is not serious.
