DefinitionBy Mayo Clinic staff
Uterine artery embolization is a minimally invasive treatment for uterine fibroids, noncancerous growths in the uterus. In uterine artery embolization — also called uterine fibroid embolization — a doctor uses a slender, flexible tube (catheter) to inject small particles (embolic agents) into the uterine arteries, which supply blood to your fibroids and uterus.
Uterine fibroids stimulate formation of new blood vessels to the fibroid. During uterine artery embolization, the embolic agents are injected into these fibroid blood vessels. The goal is to block the fibroid vessels, starving the fibroids and causing them to shrink and die.
