Introduction
Stent fracture (SF) is a rare complication of stent implantation with a reported rate of 0.84-3.2% in various clinical studies with first generation drug eluting stent (DES) and 29% in autopsy studies. Risk factors for SF are multiple stenting, long stent length, chronic renal failure, RCA intervention and a higher maximal inflation pressure. Image enhancement techniques like StentBoost are widely available in new generation angiography systems and are used to assess stent expansion, overlap size or localize the postdilation balloon. We aimed to assess the relation between stent fracture diagnosed with StentBoost and restenosis.
Materials-Method
Ninety three patients with suspected stent fracture diagnosed with StentBoost are included in this study between January 2013 and April 2015. We explored medical records, angiographic images for investigating clinical or angiographic restenosis.
