Angiographic embolization

Angiography is performed in the radiology department by an interventional radiologist who specializes in injecting arteries through a small catheter introduced into the artery with a special dye that may be seen on x-rays in real time.  Once the artery or arteries supplying the malformation are identified, plastic beads, glue or foam; substances that form a plug much like stop-leak for a radiator on a car, are injected into the artery or arteries (embolization) thus depriving the malformation of its blood supply. 

Embolization may be used as a stand-alone treatment or as part of staged therapy prior to surgical resection to lessen blood loss during the operation.
