[Artificial embolization with cyanoacrylate for the treatment of the extracranial arteriovenous malformation].

Two cases of the extracranial arteriovenous malformation (AVM) were treated by intra-arterial injection of cyanoacrylate (Aron alpha A). The first case was a 31-year-old man who had an AVM in the left temporal muscle. At operation, the feeders, the left anterior and posterior deep temporal arteries, were exposed and Aron alpha A was injected into these feeders. The pulsation of the AVM disappeared and the AVM became a hard mass. The mass was totally removed with remarkably little amount of bleeding. No complication was noted. The second case was a 23-year-old man who had an AVM in the scalp, and its feeder was the left occipital artery. The treatment was done in the same manner as in the first case. After operation the regional scalp became necrotic, but the epithelialization was completed in 3 weeks. No signs of recurrence of AVM were noted 20th and 21th month after operation in each of the cases. The recent literature were briefly reviewed.
