Embolization at UCLA

What is Embolization?

Embolization is a non-surgical, minimally invasive means of blocking the arteries that supply blood to diseased tissue such as tumors or malformations. Embolization procedure uses a microcatheter (very small plastic tube), which is navigated into the target arteries under X ray guidance. Small particles, glue, or coils are injected from the microcatheter so that the target arteries are blocked.

Embolization 1

Figure 1: A black arrow indicates a shadow of tumor (Glomus tympanicum tumor). The more blood flow the tumor is supplied, the darker the shadow becomes.

Embolization 2

Figure 2: After embolization of small arteries that feed the tumor, the shadow becomes less dense, which indicates the tumor now receives less blood supply.

Embolization is also a very effective method to control or prevent bleeding. Brain aneurysm, arteriovenous malformations and dural arteriovenous fistula can be treated by embolization.
