INTRODUCTION. The morbidity and mortality of cerebral arteriovenous malformations is mainly due to hemorrhages. OBJECTIVE. To know the situation of the embolization of arterio-venous malformations in the Carlos Andrade Marín Specialties Hospital. MATERIALS AND METHODS. Observational, retrospective study in patients with a diagnosis of cerebral arteriovenous malformations who underwent radiological intervention, during the period from January 2016 to December 2017, at the Carlos Andrade Marín Specialties Hospital. RESULTS 17 patients with inclusion criteria, most with single arteriovenous malformations and Spetzler Martin type I and II classification. 52,9% underwent the procedure with a history of intracerebral hemorrhage. After the procedure, 61,5% of obliteration was achieved on average, with 5,8% of patients having post-procedural intracerebral hemorrhage. DISCUSSION. The use of embolization allows the occlusion of the dysplastic vascular nest and the flow of deep nutritional arteries, decreasing intracerebral hemorrhage as a complication, being a precursor treatment of surgical complements or as a single treatment. The average of obliteration is within the range reported in the literature, with only one case that had post procedure complication. Complementary studies are needed where the variables of the post-procedure treatments and a follow-up to assess survival are specified. CONCLUSION. Results similar to those reported in the literature, embolization was considered as an alternative treatment, mainly as a precursor to surgery in arteriovenous malformations with Spetzler Martin classification greater than III.
