We report our experience with endovascular approach to brain arteriovenous malformations. Objective: Weemphasize the good safety profile of this approach and its potential for anatomical cure. Materials and Methods: This cohortstudy includes all patients diagnosed with a brain arteriovenous malformation who underwent therapeutic embolization inthe 4-year period, from January 2015 to December 2018 at the Endovascular Neurologic Center (CEN) of Médica Uruguaya,Montevideo Uruguay. Data were collected from clinical records and computerized databases, as well as from clinical examinationsto define current neurological and functional status according to the modified Rankin scale results. Results: 66 patients werereviewed, ranging from ages 1 to 73, 28 patients had previous bleeding, 18 had seizures, 9 were incidentally diagnosed and theremaining had minor headaches and neurological deficits. Only 3 patients underwent other therapies (2 had neurosurgeryand 1 radiosurgery). Clinical results can be considered as very good, an overall 27% of anatomic cures; the treatment-relatedmorbidity was very low, mRS 0-2 97% and mRS 3 in 3%. There were no patients with mRS 4-6. Clinical improvement wasnoted in 77.6% of patients. Conclusion: In our experience, endovascular therapy as a treatment of arteriovenous malformationsis safe, can achieve control of the disease with no changes in quality of life and can be potentially curative in certain cases.
