Drug-eluting stents (DES) reduce intimal hyperplasia and restenosis, but they also inhibit stent endothelization, making the vascular surface more thrombogenic. The present report describes two cases of in-stent restenosis after DES deployment at exactly the same sites where subacute stent thrombosis had occurred. Extremely careful follow-up is mandatory after the recognition of intraluminal thrombi inside DES because restenosis may occur at the same site of DES thrombosis.
药物洗脱支架（DES）可减少内膜增生和再狭窄，但它们也会抑制支架内皮化，使血管表面更易形成血栓。本报告描述了两例DES置入后在亚急性支架血栓形成的完全相同部位发生支架内再狭窄的病例。在识别出DES内的腔内血栓后，必须进行极其仔细的随访，因为再狭窄可能发生在DES血栓形成的同一部位。
