Fourteen cases of arteriovenous malformations (AVM) of the brain, dura and scalp were embolized with ethyl-cyanoacrylate. Injection of the ethyl-cyanoacrylate was performed either by direct puncture of the feeding arteries or transfemoral catheterization with a detachable and leak balloon catheter. For every injection, 0.3 to 1.0ml of cyanoacrylate was used. With additional surgical removal, eight AVMs were totally eradicated and the remaining AVMs were partially embolized. Among the AVMs, dural AVM was most suitable for the cyanoacrylate embolization, and a high rate (67%) of total embolization without surgical intervention was obtained.
