Endovascular treatment with isobutyl cyano acrylate in patients with arteriovenous malformation of the brain. Indications, results and complications.

Between December 1984 and May 1986 67 patients with arteriovenous malformation (AVM) of the brain have been treated with endovascular occlusion using isobutyl-cyano-acrylate at the Lariboisière Hospital. Six patients were completely cured, i.e. with complete occlusion of the malformation. In 21, reduction of the size of the AVM was obtained, permitting surgery or radiation therapy not considered possible before endovascular intervention. In 33 cases a partial cure was achieved, but additional embolization is needed. In 3 cases the treatment was interrupted. Four patients died. The overall frequency of complications was in this material around 10 per cent.
