Endovascular embolization

Image showing endovascular embolization

In endovascular embolization, your doctor inserts a long, thin tube (catheter) into a leg artery and through blood vessels to your brain using X-ray imaging. Your surgeon positions the catheter in one of the feeding arteries to the AVM, and injects small particles of a glue-like substance to block the artery and reduce blood flow into the AVM.
