Uterine artery embolization.

The use of uterine artery embolization is a new approach in the treatment of uterine fibroids. Embolization is a technique in which blood vessels that supply nutrients and oxygen to fibroids are blocked. This blockage causes the fibroid muscle cells to degenerate and form scar tissue, thus shrinking the fibroid. Usually the fibroid no longer causes symptoms. This minimally invasive procedure involves an overnight hospital stay and results in a reduction of fibroid symptoms. Most women notice the greatest improvement in the first eight weeks. This procedure has been performed only since 1990 and, therefore, long-term results are unknown.
