A 73-year-old man with 2-vessel coronary artery disease underwent a staged percutaneous coronary intervention that resulted in rupture of the right coronary artery and pseudoaneurysm formation. Although the pseudoaneurysm regressed over a week, it reexpanded after a year. Resection of the pseudoaneurysm and coronary artery bypass grafting were performed. The drug-eluting stent at the coronary artery injury site may have delayed healing and remodeling of the artery, thus contributing to reexpansion of the pseudoaneurysm.
一名患有双支冠状动脉疾病的73岁男性接受了分期经皮冠状动脉介入治疗，结果导致右冠状动脉破裂并形成假性动脉瘤。尽管假性动脉瘤在一周内有所缩小，但一年后又再次扩大。遂进行了假性动脉瘤切除术及冠状动脉旁路移植术。冠状动脉损伤部位的药物洗脱支架可能延迟了动脉的愈合和重塑，从而导致假性动脉瘤再次扩大。
