The purpose of this report is to show the imaging characteristics of saphenous vein graft aneurysms and pseudoaneurysms. Conventional radiographic, CT, and coronary angiography images were reviewed for three patients ranging from 64 to 69 years old who had documented saphenous vein graft aneurysms or pseudoaneurysms.
Saphenous vein graft aneurysms and pseudoaneurysms appear as paracardiac, hilar, or mediastinal masses on chest radiographs. On CT, the lesions are enhancing tubular mixed-attenuation masses along the heart border. Coronary angiography confirms the graft dilatations. Knowing the imaging characteristics of these entities should lead to their diagnosis and prevent unnecessary complications.
本报告旨在展示大隐静脉移植血管动脉瘤和假性动脉瘤的影像学特征。回顾了3例年龄在64至69岁之间、已确诊患有大隐静脉移植血管动脉瘤或假性动脉瘤患者的传统放射影像学、CT和冠状动脉造影图像。
大隐静脉移植血管动脉瘤和假性动脉瘤在胸部X线片上表现为心旁、肺门或纵隔肿块。在CT上，病变为沿心脏边界的强化管状混合密度肿块。冠状动脉造影可证实移植血管扩张。了解这些病变的影像学特征有助于诊断并预防不必要的并发症。
