What's the Meaning of Embolization?

(EM-boh-lih-ZAY-shun) A procedure that uses particles, such as tiny gelatin sponges or beads, to block a blood vessel. Embolization may be used to stop bleeding or to block the flow of blood to a tumor or abnormal area of tissue.

What is the purpose of embolization?

It may be used to control or prevent abnormal bleeding, close off vessels supplying blood to a tumor, eliminate abnormal connections between arteries and veins, or to treat aneurysms. Embolization is a highly effective way to control bleeding and is much less invasive than open surgery.

What happens during embolization?

Small particles (embolic agents) are injected into the uterine artery through a small catheter. The embolic agents then flow to the fibroids and lodge in the arteries that feed them. This cuts off blood flow to starve the tumors.
