A 72-year-old man with a heavily calcified coronary lesion underwent percutaneous coronary intervention (PCI) using a third-generation drug-eluting stent (DES) with thin stent struts. Two months after the PCI, in-stent restenosis due to stent recoil (SR) occurred. An intravascular ultrasound (IVUS) revealed deformed stent struts and heavily calcified coronary plaque. The SR probably occurred due to persistent vessel compression as a result of heavily calcified coronary plaque. We should consider using a DES with thick stent struts rather than a third-generation DES with thin stent struts in patients with a heavily calcified coronary lesion.
一名患有严重钙化冠状动脉病变的72岁男性接受了经皮冠状动脉介入治疗(PCI),使用的是具有薄支架梁的第三代药物洗脱支架(DES)。PCI术后两个月,由于支架回缩(SR)发生了支架内再狭窄。血管内超声(IVUS)显示支架梁变形以及严重钙化的冠状动脉斑块。SR可能是由于严重钙化的冠状动脉斑块导致持续的血管受压所致。对于患有严重钙化冠状动脉病变的患者,我们应考虑使用具有厚支架梁的DES,而非具有薄支架梁的第三代DES。
