Hemangioma refers to abnormal development of blood vessels or vascular malformations, and is broadly divided into three major categories: capillary hemangioma, cavernous hemangioma, and trabecular hemangioma. The onset and treatment of the three classifications are different. Most capillary hemangiomas occur in infants and children, and they tend to subside on their own as they develop, so most of them do not require treatment; cavernous hemangiomas are the most common type of hemangioma, and they can occur in the limbs, muscles, and even internal organs. This type of hemangioma requires surgery or interventional treatment if treatment is indicated. For example, liver hemangioma, which is often encountered, has good efficacy through interventional methods, i.e., it can be treated by intra-arterial embolization, or by radiofrequency ablation or microwave ablation, or by surgical removal; trabecular hemangioma is more extensive and, in most cases, requires surgical removal of the hemangioma.
