Abstract
The authors have treated 12 cases of cerebral AVM, five cases of dural AVM and three cases of cutaneous AVM by embolization with Aron-alpha (alkyl-α-cyanoacrylate) since 1978 according to their opinion that the most ideal method for the treatment of AVM is to completely embolize the nidus itself and to make the emboli attach to the vascular network closely for prevention of recurrence. In addition, such a method should be safe and easy. All eight cases of dural AVM and cutaneous AVM were completely embolized. Nine of the 12 cases of cerebral AVM were completely embolized with cyanoacrylate. The remain three were partially embolized. In four cases, the AVM was removed following the embolization with cyanoacrylate in order to examine how to embolize the nidus. Thus Aron-alpha attached firmly to the vascular network of the AVM-and made a hard mass like a calcification, and recurrence seems unlikely to occur. Therefore, embolization using Aron-alpha is a good treatment in difficult deep-seated AVM and dural AVM because it is easy. safe and prevents recurrence.
