Aneurysms of the left main coronary artery are rare clinical entities with an incidence of 0.1%. We herein report a case of left main trifurcation aneurysm in a 57-year-old woman whose coronary angiography demonstrated a giant saccular aneurysm of trifurcation of the left main coronary artery, measuring 32 × 21 mm with tight post-aneurysmal stenosis in the intermediate artery. The patient underwent coronary artery bypass grafting following the resection of CAA and reconstruction with saphenous vein roof-plasty, which ensured the preservation of the native coronary vasculature. At the 6-month follow-up, she remained asymptomatic and preserved preoperative left ventricular function.
左主干冠状动脉瘤是罕见的临床病症，发病率为0.1%。我们在此报告一例57岁女性的左主干三叉动脉瘤病例，其冠状动脉造影显示左主干冠状动脉三叉处有一个巨大的囊状动脉瘤，大小为32×21毫米，中间动脉动脉瘤后有严重狭窄。患者在切除冠状动脉瘤并采用大隐静脉屋顶成形术重建后接受了冠状动脉旁路移植术，这确保了原生冠状动脉血管系统的保留。在6个月的随访中，她仍无症状，术前左心室功能得以保留。
