Uterine artery embolization (UFE) is a minimally invasive treatment for uterine fibroids, noncancerous growths in the uterus. A UFE essentially starves a fibroid of blood, glucose, and oxygen by blocking the arteries flowing to the fibroid, causing it to reduce in size and eventually disappear. The physician uses angiogram technology to guide the catheter to the arteries that supply blood to the fibroid. A solution of polyvinyl alcohol (PVA) particles is then injected into those uterine arteries through the catheter. These particles build up in the targeted arteries and block blood flow to the fibroid.
