Cyanoacrylate encasement of intracranial aneurysms

✓ Some intracranial aneurysms, because of their broad base or incorporation of essential nutritive vessels, must be treated by adhesive reinforcement. The authors report successful results with cyanoacrylate adhesives in five patients. The unique quality of this material permits maximum adhesion in a moist operative field. This adhesive is nonviscous and will coat the entire aneurysm, obviating problems related to incomplete coating. Excellent long-term results are apparently due to the biological effect of this adhesive in which a proliferative fibrous reaction occurs and counteracts recognized erosive properties.
