An unusual complication after aortocoronary bypass grafting (CABG) is described in which a false aneurysm of the saphenous vein graft to the right coronary artery (RCA) developed and caused profuse intermittent bleeding through the sternotomy wound. The aetiology of this condition is uncertain but it could occur whenever a suture line is present especially in the presence of infection. The diagnosis was made non-invasively by a contrast enhanced computed tomogram and was subsequently confirmed by selective coronary bypass angiography. The pseudoaneurysm was successfully obliterated by coil embolisation of the right coronary graft, which stopped the bleeding immediately and was followed by rapid wound healing.
本文描述了一例主动脉冠状动脉旁路移植术(CABG)后出现的罕见并发症,即右冠状动脉(RCA)的大隐静脉移植血管发生假性动脉瘤,并通过胸骨切开伤口导致大量间歇性出血。这种情况的病因尚不确定,但只要存在缝线,尤其是在有感染的情况下,就可能发生。通过对比增强计算机断层扫描进行无创诊断,随后经选择性冠状动脉旁路血管造影证实。通过对右冠状动脉移植血管进行弹簧圈栓塞成功消除了假性动脉瘤,出血立即停止,随后伤口迅速愈合。
