We report a case with a large aneurysm of right coronary artery (RCA) associated with coronary artery disease. The aneurysm was sealed with two PTFE-covered stents using a sequential technique from proximal to distal to overcome the lack of long PTFE-covered stents and existence of complex coronary anatomy. A bare metal stent was subsequently deployed to treat a lesion in the mid part of RCA. At 4-month follow-up, aneurysm was completely sealed and no restenosis occurred. Usage of sequential PTFE-covered stents enables treatment of large coronary artery aneurysms.
我们报告一例伴有冠状动脉疾病的右冠状动脉（RCA）大动脉瘤病例。为克服长段聚四氟乙烯（PTFE）覆膜支架短缺及复杂冠状动脉解剖结构的问题，采用从近端到远端的序贯技术，用两个PTFE覆膜支架封闭动脉瘤。随后植入一枚裸金属支架治疗RCA中段病变。在4个月的随访中，动脉瘤完全封闭，未发生再狭窄。序贯使用PTFE覆膜支架可治疗大型冠状动脉瘤。
