ABSTRACT

Objective: To show the experience of the functional neurosurgery, stereotactic and radiosurgery unit on the treatment of arteriovenous malformation (AVMs) an determinate the grade of obliteration and the mobility associate to this procedure. Material and methods: We treated 173 patients between November 1999 to December 2006, 53 patients with least 3 year of following. All treated by radiosurgery clinic from General Hospital of Mexico with linear accelerator (LINAC). Results: 28 women y 23 men treated, aged between 6 to 64 years. 14 patients presented brain hemorrhage before de therapeutic procedure. The most frequent localization of the AVMs where; parietal 13, temporal 11, frontal 10, brain steam 9, diencephalon 7 and cerebellum 1. The volume oscillated at less 10cm³ on 41 cases. 1 patient received endovascular therapy previous radiosurgery and in 2 cases performed partial resection by microsurgical technique before of treatment. 2 patients with posterior deficit after the radiosurgery procedure. The rate of total obliteration of AVMs was 97.5% at 3 years. Conclusions: The radiosurgery as a therapeutic modality on the treatment of brain arteriovenous malformations are highly effective, with minimum mobility an none mortality associated to the procedure.
