Late angiographic stent thrombosis in a drug-eluting stent that occurred 20 months after premature discontinuation of clopidogrel administration

Abstract

Late angiographic stent thrombosis (LAST) in a drug-eluting stent has been reported in several studies. Most LAST occur just after discontinuation of antiplatelet therapy. We report the first case of LAST that occurred 21 months after implantation of a Cypher stent and 20 months after discontinuation of clopidogrel, results that suggest a mechanism other than the discontinuation of antiplatelet therapy might be responsible for LAST.
