Giant aneurysm of saphenous vein graft to right coronary artery Mohammed W. Khalil, Syed S. Qadri, FRCS, and Mubarak Chaudhry, FRCS A 64-year-old white man presented with hemoptysis. He underwent coronary artery bypass grafting (CABG) in 1982, followed by a redo-CABG in 1992, which involved a venous graft to his right coronary artery. A chest radio- graph revealed a large shadow on the right border of the heart. This was thought to be a lung tumor, because he is a smoker. Chest computed tomography (CT) revealed that it was a large aneurysm of the saphenous vein graft to the right coronary artery (Figures 1 and 2). The graft was pat- ent, with a large lumen and a large clot in the aneurysmal portion, compressing the right atrium but not causing symp- toms, possibly because of its insidious and slow progress. The hemoptysis was the result of an infective process in the left upper lobe of the lung, which resolved with antibiotics. True aneurysms of aortocoronary saphenous vein grafts are a relatively rare complication of bypass surgery. 1,2 Complications of thrombosis, embolization, or rupture are potentially fatal and, therefore, require immediate surgical intervention. 2,3 However, our patient had multiple comor- bidities, and surgical intervention was considered to have an unacceptable risk. Care must therefore be taken while interpreting CT scans in patients presenting with respiratory tract symptoms, be- cause this could be confused with pericardial cysts or lung masses, especially if the graft completely blocked and filled with thrombus. The history of CABG should raise a high index of suspicion. References 1. Chiappini B, Poncelet A, Noirhomme P, Verhelst R, Rubay J, Funken JC, et al.
