Peri-Contrast Staining as a Marker of Stent Failure: Restenosis, Thrombosis, and Fracture

The introduction of stents has led to significant improvement in the management of coronary artery disease. In-stent thrombosis, target lesion revascularization, and stent fracture (SF) have been identified as causes of in-stent restenosis. Peri-contrast staining (PSS) has been associated with in-stent restenosis, stent thrombosis, stent fracture, and the development of coronary aneurysm. As the frequency of patients with first generation sirolimus-eluting coronary stents becomes infrequent; PSS may go unrecognized. Herein, we present a patient with a decade of longitudinal follow-up, who developed PSS identified on coronary angiogram with recurrent stent failure.
