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

Abstract: BackgroundLocalized 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 thrombi in patients with DES VLST.Methods and ResultsFrom April 2004 to September 2012, 48 patients with stent thrombosis… Show more

“…The mechanism of VLST after DES implantation is assumed thrombus formation associated with incomplete neointimal coverage over the stent struts or with neoatherosclerosis . At the late stage after implantation, neointimal coverage over the stent struts are often lacking in case of DES, although struts of BMS are covered with neointima.…”

“…Помимо проблем позднего и очень позднего тромбоза стента, актуальность приобрела проблема рестеноза стента в среднеотдаленном и отдаленном периоде. Причинами этого могут быть как дисплазия и нарушения пролиферации неоинтимы, так и неоатерогенез [4,10,12]. Концепция неоатеросклероза активно обсуждается в литературе, а причинно-следственные связи неоатеросклероза и ЧКВ до конца не раскрыты.…”

“…[44] These differences may also explain the rare complications of very late stent thrombosis characterized by vasculitis and high fractions of eosinophilic cells. [45] There are still a great many unknowns regarding the healing response to drug eluting molecules that need to be addressed by future studies.…”
