Abstract
N-butyl-cyanoacrylate is liquid adhesive non-absorbable embolic material whose permeability is very stable. Such materials must be liquid at the time of injection and should solidify when they reach the pathological angioarchitecture, producing an endovascular cast of the area without passing into the venous circulation or distal arterial territory. If superselectivity is accomplished and no normal or endangered vessels are present, one can inject acrylic as a continuous column to produce an intravascular cast. An important part of the management of angioma is educating the patient. NBCA embolization for arteriovenous malformation can be carried out as a unique treatment, the intended goal being partial and targeted, palliative, curative, or in combination with surgery or stereotactic radiosurgery. It may be given as elective treatment or in emergent fashion, depending on the indication and circumstances. The indication to use this embolic material should be well considered in the clinical management of angioma and the arteriovenous malformation in the central nervous system.
