Drug eluting stents have led to a substantial reduction of in-stent restenosis. Stent fracture (SF) is an important cause for the cases of restenosis which still occur. Sites of increased vessel movement, long stents, and overlapping stents have been observed to be more prone to fracture. We report the case of a patient with multiple drug eluting SFs at the site of coronary artery bypass insertion. The decision to implant stents at the site of bypass insertion should be made carefully. SF should be considered when gaps between previously implanted stents are observed.
药物洗脱支架已使支架内再狭窄大幅减少。支架断裂（SF）是仍会发生的再狭窄病例的一个重要原因。已观察到血管活动增加的部位、长支架和重叠支架更容易发生断裂。我们报告了一例在冠状动脉搭桥插入部位出现多个药物洗脱支架断裂的患者病例。在搭桥插入部位植入支架的决定应谨慎做出。当观察到先前植入的支架之间存在间隙时，应考虑支架断裂情况。
