Résumé
Objective: To present our experience on endovascular embolization by using N-butyl cyanoacrylate and to demonstrate that this is an effective method in the treatment of brain arteriovenous malformations. Malerials and Methods: From 1992 to 1998, 92 patients with brain arteriovenous malformations who having had endovascular embolization as primary treatment was retrospectively reviewed. Results: 8 patients (8.7%) had completely cure by embolization alone wthout neurological complication. 17 patients (18.5%) were cured after combined treatment, 9 with surgical removal and the other 8 with radiosurgery. The neurological complications occurred in 17 patients (18.5%) with 3 deaths and vegetative stage. Conclusion: The endovascular embolization can cure the arteriovenous malformations that smaller than 3 cm, no matter what its location, and it is effective to reduce the nidus volume of the larger lisions, making them suitable for surgical resection or radiosurgery as to achieve te goal of complete eradication of the malformations.
