Mainly according to the location of hemangioma formation, decide which department to go to for specialist treatment. For example, intracranial aneurysms in the head are at risk of cerebral hemorrhage at any time. If the amount of bleeding is large and the treatment is not timely, the patient will have sequelae. If the bleeding occurs in the brain stem, it may even be life-threatening. Intracranial aneurysm needs neurosurgery. Craniotomy can be performed to remove aneurysms, and embolization can also be performed. For hemangioma of limbs, vascular surgery is needed.
