The use of the ?cross over technique? in the management of a traumatic vertebro-vertebral fistula

Abstract
A case of dissecting stab wound injury to the right vertebral artery with a vertebro-vertebral fistula is reported. Since a complete occlusion of a VV-fistular was not possible from a proximal approach with detachable balloons only retrograde catheterisation of the right vertebral artery via the left vertebral artery was undertaken (cross over technique). The introduction of thrombogenic platinumcoils led to a successful and complete occlusion of the fistula.
