Saphenous vein graft aneurysm after coronary artery bypass surgery.
OBJECTIVE
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.


CONCLUSIONS
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.
