Very late intrastent thrombotic occlusion caused by neoatherosclerosis after bare-metal stent implantation in the superficial femoral artery: Insight from histopathological findings
Abstract:A 58-year-old male with gangrene in his left 1 st digit due to critical limb ischemia had undergone endovascular therapy for chronic total occlusion of the left superficial femoral artery using bare-metal stents (BMSs). Angiography revealed in-stent occlusion of the BMS site when he was referred to our hospital with a recurrent ulcer at 7 years after stent implantation. As catheter-directed thrombolysis with urokinase was not effective, surgical thrombectomy was performed. His ankle-brachial index improved, an… Show more
“…Neoatherosclerosis has been reported as one of the major causes of VLST in the coronary arteries; however, it has rarely been reported in the peripheral arteries. 1 Okuno et al reported histopathological findings with disruption of in-stent neoatherosclerosis from retrieved thrombi in very late intrastent thrombotic occlusion after BNS implantation in the SFA. 2 However, this case illustrates valuable direct visualization with multimodality imaging of a case with VLST caused by rupture of in-stent neoatherosclerosis 15 years after BNS implantation, and the value of multimodality imaging for comprehensive evaluation to diagnose the mechanism of VLST in SFA.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
