Aneurysms of saphenous vein grafts to coronary arteries are unusual complications of coronary artery bypass graft (CABG) surgery. Three patients (men aged 47, 62, and 68 years) are presented with spontaneous chest pains 10, 21, and 17 years after CABG surgery. In one case, the saphenous vein graft had eroded into the right atrium and had established a fistula between the graft and the right atrium. Diagnosis of saphenous vein graft aneurysms was confirmed by echocardiography, computed tomography or magnetic resonance imaging, and by arteriography. Two patients were treated surgically, the third by percutaneous coil embolisation followed by balloon angioplasty of the right coronary artery.
冠状动脉大隐静脉移植血管动脉瘤是冠状动脉旁路移植术（CABG）手术中不常见的并发症。本文报告了3例患者（年龄分别为47岁、62岁和68岁男性），在CABG手术后10年、21年和17年出现自发性胸痛。其中1例患者，大隐静脉移植血管侵蚀入右心房，并在移植血管与右心房之间形成了瘘管。通过超声心动图、计算机断层扫描或磁共振成像以及动脉造影确诊为大隐静脉移植血管动脉瘤。2例患者接受了手术治疗，第3例患者先接受经皮线圈栓塞治疗，随后对右冠状动脉进行球囊血管成形术。
