What is interventional therapy for infantile hemangioma?

Generally, interventional therapy for infantile hemangiomas is a minimally invasive treatment approach that achieves therapeutic goals through precise intervention in the affected blood vessels, and is suitable for specific types or severe cases of hemangiomas. Detailed analysis is as follows:

This treatment uses catheterization techniques to deliver embolic materials or medications through blood vessels to the feeding arteries of the hemangioma, blocking blood flow or inhibiting proliferation of vascular endothelial cells, thereby causing the lesion to gradually shrink due to lack of nutrition. The entire procedure is performed under image guidance, resulting in minimal trauma, accurate targeting, reduced damage to surrounding healthy tissues, and faster postoperative recovery.

This therapy is primarily indicated for large, rapidly growing hemangiomas or those located in critical areas such as joints or near the eyes, especially in infants who cannot tolerate surgical excision. Prior to treatment, imaging studies are required to clearly define the extent of the hemangioma and its blood supply, allowing for an individualized treatment plan that avoids injury to normal vessels.

After treatment, close monitoring of the puncture site for bleeding or swelling is necessary, and the area should be kept clean and dry. Patients should rest adequately and avoid strenuous activity. Regular follow-up evaluations are essential to assess treatment effectiveness, ensure gradual regression of the lesion, and minimize impact on the infant’s growth and development.
