Abstract
This is a report of the endovascular treatment of three intracranial dural arteriovenous malformations (DAVM) using Onyx.We analyzed the clinical and angiographic results in three patients with intracranial DAVM, revealed by a hemorrhagic event and treated by endovascular way by the use Onyx. Angiographic investigation showed the DAVM to be located in the lateral sinus in two cases and in the tentorium region in the third.In all three cases, embolization was performed by selective catheterization of the meningeal arterial feeder of the DAVM. The injection of Onyx resulted in complete anatomical exclusion of the DAVM, as demonstrated by posttreatment angiography. Clinically, the patients recovered partially or completely their neurological deficit.Onyx is a liquid embolization agent recently introduced for the treatment of DAVM. When used under optimal conditions, it offers a feasible alternative option in the treatment of such vascular malformations.
