How should angiomas be treated?

The treatment of vascular nevi mainly includes: 1. **Drug therapy**: Under the guidance of a physician, oral corticosteroids such as prednisone and dexamethasone may be prescribed, or topical imiquimod cream may be used. These medications can inhibit blood vessel formation and promote the lesion to enter the stabilization and regression phases earlier. 2. **Physical therapy**: Commonly used methods include laser therapy and cryotherapy. Laser therapy utilizes selective photothermolysis to induce vascular occlusion and is effective for superficial vascular nevi. Cryotherapy achieves therapeutic effects by freezing and causing necrosis of the vascular nevus tissue. 3. **Surgical treatment**: For larger hemangiomas or cases unresponsive to medication or physical therapy, surgical excision such as excision of the vascular nevus may be performed. 4. **Other treatments**: These include sclerotherapy, photodynamic therapy, radiotherapy, and interventional radiology techniques, which are suitable for different types of vascular nevi.
