The iatrogenic anastomosis of left internal mammary artery to a cardiac vein is a rare complication of coronary artery bypass surgery, potentially leading to recurrent chest pain or myocardial infarction. Contrast angiography is currently the gold standard to assess by pass graft patency, but it is an invasive procedure and a potentially harmful diagnostic method with a small risk of complications. Recently non-invasive method such as conventional computed tomography (CT) has been evaluated for the assessment of by pass graft patency. This report highlights the non-invasive use of 64-slice CT scan to accurately identify an uncommon error of distal anastomosis of the left internal mammary artery to a cardiac vein during bypass surgery.
