Occlusion of cerebral arteriovenous malformations with N-butyl cyano-acrylate is permanent.
OBJECTIVE
To verify the permanence of total occlusion of cerebral arteriovenous malformations after embolization with N-butyl cyano-acrylate and to evaluate the occlusion rate.


METHODS
One hundred thirty-four patients were treated for cerebral arteriovenous malformations with N-butyl cyano-acrylate embolization after superselective catheterization. Those initially totally occluded have been followed with angiography.


RESULTS
In 15 instances (11.2%) the arteriovenous malformations were totally occluded by embolization alone. Follow-up angiograms have been performed in 12 cases (80%) after 4 to 78 (mean, 27) months after embolization. In all instances the arteriovenous malformations have remained occluded, and there have been no clinical signs of activity.


CONCLUSIONS
After total occlusion of a cerebral arteriovenous malformation with N-butyl cyano-acrylate, the lesion stays occluded, and the clinical course seems stable.
