Tips and Pitfalls in Using the Jailed Catheter Technique to Insert a Catheter into a Vertebral Artery Aneurysm via the Contralateral Vertebral Artery

Abstract

We present two cases of vertebral artery aneurysm, and investigate usability, including tips and pitfalls, of the jailing technique for catheter insertion via the contralateral vertebral artery. This technique is especially useful when direct caudal insertion of the jailed catheter is preferential. Additional devices may be needed to cross the vertebra-basilar junction. For stable and safe embolization, coaxial usage of a distal access catheter is highly recommended.
