Embolization is used to treat a variety of malformations.
To prevent bleeding, patients may need embolization before surgical removal of the malformation or debulking of overgrown tissue.
When lesions are large and surgery is not possible, embolization may help to improve quality of life. It can help to decrease complications caused by the lesion.
Certain malformations may need several treatments to completely block the abnormal vessels. Treatments are spaced several months apart. Long-term follow-up and evaluation are required.
