The authors described two cases of dural arteriovenous malformation treated by arterial embolization.
In a case of transverse sinus dural arteriovenous malformation, embolization was performed by the use of Gelfoam and in another case of cavernous sinus dural arteriovenous malformation, Gelfoam coated with Gutta-percha was used.
In the experimental brain stem infarction in the dog, we found a thrombogenic effect of Guttapercha. Therefore we used Gutta-percha Gelfoam for arterial embolization in one case. If Guttapercha Gelfoam is implanted in the arteriovenous malformation exactly, it promotes the thrombogenesis of the fistula and gives rise to the possibility that dural arteriovenous malformation can be occluded.
