Hepatic hemangioma is a relatively common benign tumor of the liver, clinically cavernous hemangioma is the most common, with a natural population autopsy detection rate of 0.35-7.3%, accounting for 5-20% of benign liver tumors. In recent years, with the improvement of people’s awareness of health checkups and the advancement of various imaging diagnostic techniques, the detection rate of asymptomatic small hemangiomas has increased significantly, which often brings many problems and anxiety to patients, and we hope the following introduction can give patients some comfort. 1.Where do hepatic hemangiomas come from? Hepatic hemangioma is also known as hepatic sponge hemangioma, and as the name suggests, most of the tumor is filled with diffuse sponge-like blood vessels. The exact cause of hemangioma is not very clear, but it may be due to congenital malformation of the terminal blood vessels of the liver, or it may be related to diet or hormonal drugs. Hepatic hemangiomas can be solitary or multiple and have a slow course, often over years or even decades, with a large number of collagen fibers forming in the center. Therefore, most of the hepatic hemangiomas tend to be stable and do not require external intervention. 2.Can hepatic hemangioma grow or rupture suddenly? Hepatic hemangioma is a benign disease and will not become malignant, and most of them develop slowly. The common understanding that hemangiomas can rupture and bleed is actually extremely rare. Strictly speaking, hemangiomas do not rupture on their own. If an external force can cause a tumor to rupture, then for that area of liver tissue, even without a hemangioma, that force can cause the liver to rupture. Not to mention that we have the rib cage for protection. Of course the large superficial hemangioma will be relatively easy to crack in the case of high impact force such as combat or car accident injury. 3.Does hepatic hemangioma cause discomfort? Many middle-aged women find hemangiomas because they have pain or discomfort when they go to the hospital for physical examination. But in fact, hemangioma below 5cm usually does not produce any symptoms. Only when the hemangioma grows significantly and presses on the stomach, duodenum and other adjacent organs does it cause symptoms such as upper abdominal discomfort, bloating, belching and abdominal pain. Therefore, patients with small hemangioma of the liver combined with physical discomfort need to exclude biliary tract and gastrointestinal diseases. 4.Do I need surgery for hepatic hemangioma? For most people, after the diagnosis of hemangioma, only regular ultrasound examination is needed, once every six months, to dynamically observe the change of its size, and if it does not increase significantly, it can be medically observed. However, if the hemangioma is larger than 5cm, or if the hemangioma is prone to rupture or has obvious stomach discomfort (mass or mass pressure symptoms), surgery is recommended to remove it. 5.What kind of surgery should I choose for hepatic hemangioma? If the hemangioma is less than 10cm, minimally invasive treatment (laparoscopic), radiofrequency or microwave treatment are recommended. 6.What about multiple hemangiomas? The principle of handling multiple hemangiomas is not essentially different from that of single hemangioma, and multiple hemangiomas can be considered to be removed at the same time during the surgery. However, if the combined hemangioma is very small (within 2cm), our treatment principle is considered according to the degree of trauma: if it is on the surface of the liver, active treatment, and close observation is sufficient if it is deep in the parenchyma. 7.Does hepatic hemangioma recur? It is likely that many patients with hepatic hemangioma who are followed up after surgery will also have a relatively small hemangioma detected by ultrasound. Most of these small lesions are not related to the original resected tumor. The source of these small lesions is probably the change of some small blood vessels in the liver itself, so follow-up observation is sufficient.
