Abstract

A 55-year-old man had undergone successful percutaneous intervention with a sirolimus-eluting stent, placed in the right coronary artery (2.5 x 33 mm) and distal left circumflex artery (3.0 x 28 mm) without high pressure ballooning. Twelve months later he presented with unstable angina. Angiography revealed two fracture sites on the right coronary artery-deployed stent, with a large aneurysm and an aneurysmal dilatation of the left circumflex artery without stent fracture. Due to the potential risk of aneurysmal rupture, he underwent coronary artery bypass grafting and ligation of the aneurysm.

摘要

一名55岁男性曾成功接受经皮介入治疗，在右冠状动脉（2.5×33毫米）和左旋支动脉远端（3.0×28毫米）植入西罗莫司洗脱支架，未进行高压球囊扩张。12个月后，他出现不稳定型心绞痛。血管造影显示右冠状动脉植入的支架有两个断裂部位，伴有一个大动脉瘤，左旋支动脉有动脉瘤样扩张但无支架断裂。由于动脉瘤破裂的潜在风险，他接受了冠状动脉搭桥术并结扎了动脉瘤。
