Regarding the surgical risk of hemangioma, the risk is determined by the site where the hemangioma arises and the patient’s general condition. If the patient is an elderly person with many underlying diseases, such as hypertension, coronary heart disease, renal insufficiency or kidney failure, or abnormal liver function, the risk of surgery in this case will be higher. If the patient is a young person who does not have many complications caused by hemangioma and is in relatively good health, the risk of surgery will be reduced in this case. If the hemangioma grows on the surface of the body, that is, around the skin, the risk of treatment is very small. If the aneurysm grows in the internal organs, such as splenic aneurysm, superior mesenteric aneurysm, aortic coarctation aneurysm, abdominal aortic aneurysm, or aneurysm of head vessels, the treatment risk is still very high, especially for aortic aneurysm and head aneurysm, the risk is very high.
