Stent luxation: Possible complication of subadventitial stenting in coronary chronic total occlusion revascularization.

The entry to the subadventitial space is not a mode of failure, but the road to success in many chronic total occlusion (CTO) percutaneous coronary intervention (PCI) cases. Long-term clinical outcomes of subadventitial stenting are favorable and similar to intraluminal stenting. However, the subadventitial space histology and physiology remains different to the coronary true intraluminal space. We report a complication specific to stenting of the subadventitial space, where overlapping stents dislocated from one another, which resulted in late non-occlusive stent thrombosis. We describe, for the first time in the literature, this complication, possible reasons behind, and the ways to avoid this potentially major mischief. © 2016 Wiley Periodicals, Inc.
