Fifteen years after aortocoronary bypass surgery, a 52-year-old asymptomatic man was found to have a large anterior mediastinal mass. Angiographic studies showed no evidence that a vascular structure was responsible. At operation, a saphenous vein graft to the left anterior descending artery was found to be affected by a large thrombus-filled aneurysm. This is one of the few known cases in which such an aneurysm has presented as a mediastinal mass.
在接受主动脉冠状动脉搭桥手术后15年,一名52岁无症状男性被发现前纵隔有一个巨大肿块。血管造影研究未发现血管结构异常的证据。手术中发现,一根连接左前降支动脉的大隐静脉移植物受到一个充满血栓的大动脉瘤影响。这是已知少数几例此类动脉瘤表现为纵隔肿块的病例之一。
