Development of coronary artery aneurysm after implantation of a drug-eluting stent is a rare complication. The mechanism behind aneurysm formation is unknown, but studies suggest hypersensitivity and inflammatory reactions elicited by the stent polymer. Here, we report a case of a 57-year-old man who was treated with a sirolimus-eluting Cypher stent in the left anterior descending artery due to stable angina pectoris and left circumflex artery due to dissection. Coronary aneurysm formation at the site of stent implantation was discovered three years after the stents were deployed, and progression of the aneurysms was seen in the coronary artery angiography. We hypothesize about the mechanism of aneurysm formation and present management of the aneurysms.
药物洗脱支架植入后冠状动脉瘤的形成是一种罕见的并发症。动脉瘤形成背后的机制尚不清楚，但研究表明是由支架聚合物引发的超敏反应和炎症反应。在此，我们报告一例57岁男性患者，因稳定型心绞痛在左前降支植入西罗莫司洗脱Cypher支架，因夹层病变在左旋支植入该支架。支架植入三年后在支架植入部位发现冠状动脉瘤形成，并且在冠状动脉血管造影中可见动脉瘤进展。我们对动脉瘤形成的机制进行了推测并介绍了动脉瘤的处理方法。
