Very Late Stent Thrombosis Due to Late Stent Malapposition

Very late stent thrombosis with bare-metal stent: identifying severe stent malapposition and underexpansion by intravascular ultrasound

A 60-year-old man with a history of implantation of two bare-metal stents 2 years prior presented to the emergency department with new-onset chest pain. He has been regularly taking angiotensinconverting enzyme inhibitors, beta blockers and aspirin. Aspirin was suspended for 10 days prior to the current hospitalization in order to perform surgery to remove a kidney tumor. He underwent coronary ...

Association of Localized Hypersensitivity and In-Stent Neoatherosclerosis with the Very Late Drug-Eluting Stent Thrombosis

BACKGROUND Localized hypersensitivity reaction, delayed arterial healing, and neoatherosclerosis inside the stent have been suggested as the underlying pathologic mechanisms of very late stent thrombosis (VLST) of drug-eluting stent (DES). The present study sought to explore the prevalence of inflammatory cell infiltrates and evidence for fragments of atherosclerotic plaques in the aspirated th...

Very Late Stent Thrombosis after Drug-Eluting Stent Implantation in a Patient without Aspirin and Clopidogrel Resistance

Very late stent thrombosis (VLST) after implantation of drug-eluting stent is rare, but very fatal complication after percutaneous coronary intervention. We report a case of VLST of a sirolimus-eluting Cypher stent (Cordis, Johnson and Johnson) presenting as acute ST elevation myocardial infarction at 26 months after deployment with continued combined dual antiplatelet medication of aspirin and...
