Embolization of Arteriovenous Malformations (AVMs) and Tumors

Embolization is a non-surgical, minimally invasive procedure that can:

• Block the abnormal blood flow to an AVM
• Shrink tumors
• Prevent blood clots
• Stop an aneurysm

How Embolization Works

During embolization, a UPMC neurosurgeon:

• Threads a small catheter or tube through a blood vessel in the groin.
• Navigates the catheter to blood vessels in the brain.
• Guides small coils or detachable silicon balloons through the arteries to create an emboli or block blood flow to an area of the brain or body.
