What is embolization?

Embolization is a minimally invasive procedure that treats a disorder by blocking the flow of your blood to an affected organ or region. Generally, your physician will attempt embolization by injecting an agent into your body that will slow or stop the flow of blood to a particular location.

Embolization is common in the treatment of cancer; depriving a tumor of blood flow can reduce its size (allowing a surgeon to remove it) or eliminate it altogether.

In addition to many types of cancerous tumors, embolization is a useful treatment option for:

  • Brain aneurysm
  • Poor connections between the arteries and veins in the brain
  • Problems with arteries in your neck
  • Internal bleeding
  • Thickening and scarring of liver and kidney tissue
  • Benign tumors (fibroids) in the uterus

Potential side effects of embolization are rare, and they include:

  • Bleeding at the injection site
  • Internal bleeding
  • Artery damage at the point of injection
  • Infection
  • Stroke
