A 61-year-old patient who underwent emergent coronary angiography and drug-eluting stent implantation of a calcified left anterior descending coronary artery returned 2 days later with recurrence of chest pain and anterior ST-segment elevation. Three-dimensional OCT revealed extensive fracture and distortion of the struts in the distal portion of a stent, presumably caused by aggressive postdilation at the time of implantation. This was managed successfully with the insertion of a new coronary stent inside the damaged stent segment.
一名61岁患者接受了急诊冠状动脉造影及钙化的左前降支冠状动脉药物洗脱支架植入术，两天后因胸痛复发及前壁ST段抬高复诊。三维光学相干断层扫描显示支架远端部分的支柱广泛断裂和变形，推测是由于植入时强力后扩张所致。通过在受损支架节段内插入新的冠状动脉支架成功解决了这一问题。
