Adjuvant Embolization With <i>N</i> -Butyl Cyanoacrylate in the Treatment of Cerebral Arteriovenous Malformations

Abstract

Small and large size, eloquent location, deep venous drainage, and complex vascular anatomy requiring multiple embolization procedures are risk factors for the development of immediate postembolization neurological deficits. Nevertheless, a significant number of patients with treatment-related neurological deficits improve over time. The low incidence of permanent neurological deficits underscores the usefulness of this technique in carefully selected patients.
