Endovascular Balloon-Assisted Embolization of Intracranial and Cervical Arteriovenous Malformations Using Dual-Lumen Coaxial Balloon Microcatheters and Onyx

Abstract

The balloon microcatheters showed excellent navigability, and there were no problems with retrieval or with the repeated inflation and deflation of the balloons. A proximal Onyx plug, which is crucial in many AVM embolizations, was not necessary with this technique. Additionally, fluoroscopy and procedural times seemed lower with this technique compared with conventional embolization methods.
