Endovascular Treatment of Brain Arteriovenous Malformations in Siriraj Hospital

Abstract

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. Materials 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 without 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 the goal of complete eradication of the malformations.
