Balloon Bridge: Novel Technique for Reaccessing Carotid Artery Stent.

Background: Crossing a nascently deployed carotid artery stent (CAS) is required to perform angioplasty and filter recapture. If the traversing balloon or filter recapture catheters are eccentric or tangentially angled to the vertical axis of the CAS, they can ensnare on the ledge of the proximal CAS step-off, potentially causing life-threatening complications secondary to deformation, displacement, or mechanical occlusion of the stent. We report a novel "balloon bridge" technique that facilitates safe entry and passage across the CAS with both a balloon catheter and a large-bore guide catheter (LBGC).
