The necessity of using Gamma Knife for the treatment of hemangioma in the brain should be decided according to the patient’s condition. If you have a hemangioma in the brain, you need to be treated by surgery as early as possible to prevent the rupture of the hemangioma at a later stage. If the brain hemangioma is small in size or cannot be completely removed by surgery, Gamma Knife treatment is an option. Gamma Knife treatment is a kind of radiation therapy, which can produce high heat effect through radiation and irradiate the local diseased tissues, so as to achieve the effect of cure. For the treatment of hemangioma in the brain, the main clinical options are craniotomy or minimally invasive endovascular embolization intervention. If the hemangioma cannot be removed by surgery or the size of the hemangioma is too small for embolization and intervention, gamma knife treatment can be chosen.
