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.
