Giant vein graft aneurysm.

A hemodialysis patient presented with an abnormal CXR (Panel A) 13 years after coronary artery bypass grafting and a CT scan was performed (Panel B). Maximal-intensity-projection (Panel C) and 3D reconstructions (Panel D) revealed a large aneurysm, containing thrombus, arising from the vein graft to his right coronary artery (Fig. 1). Fig. 1.
