A rare case of giant coronary artery ectasia associated with coronary artery aneurysm was recognized. A 69-year-old woman presented with an ischemic electrocardiogram changes during a medical check-up. Coronary computed tomography angiography showed right coronary artery (RCA) ectasia associated with a giant aneurysm originating from the distal RCA. She was asymptomatic and exhibited no risk factors, including Kawasaki disease, hypertension, diabetes mellitus or family history. The patient underwent surgery for giant coronary aneurysms to prevent rupture. The aneurysm was on the peripheral side of the right coronary artery; hence, coronary artery bypass was not performed. The patient's postoperative course was uneventful. Histopathological examination of the aneurysm revealed degeneration due to atherosclerosis. She was prescribed warfarin and aspirin for thrombus prevention.
一例罕见的巨大冠状动脉扩张合并冠状动脉瘤被确诊。一名69岁女性在体检时出现缺血性心电图改变。冠状动脉计算机断层扫描血管造影显示右冠状动脉（RCA）扩张，伴有一个起源于RCA远端的巨大动脉瘤。她没有症状，也没有包括川崎病、高血压、糖尿病或家族史在内的危险因素。患者接受了巨大冠状动脉瘤手术以预防破裂。动脉瘤位于右冠状动脉外周侧；因此，未进行冠状动脉搭桥术。患者术后恢复顺利。动脉瘤的组织病理学检查显示为动脉粥样硬化性退变。她被开了华法林和阿司匹林以预防血栓形成。
