Embolization Main

What is an embolization procedure?

An embolization procedure is performed like an angiography procedure. A vascular catheter is introduced and advanced in to the artery to be treated. Small particles suspended in a water solution are injected through the catheter into the lumen (interior) of the artery. The blood flow carries the particles downstream into smaller vessels. As the particles enter smaller blood vessels they plug the vessel and prevent the flow of blood. This results in a decrease of blood flow to a tumour, vascular malformation or other abnormality.

Different types of embolizations

  1. Embolization for treatment of severe nose bleeds

  2. Pre-operative embolization of tumors e.g. Meningioma

  3. Embolization of vascular malformations e.g. Facial Arteriovenous Malformation

  4. Embolization for the treatment of vascular connections or fistulas. e.g.Dural Arteriovenous Fistula
