Summary Two cases of coronary subclavian steal syndrome after coronary artery bypass grafting Ugeskr Læger 2008;170(14):1158 Reverse flow in the internal mammary artery (IMA) graft due to stenosis or occlusion of the proximal ipsilateral subclavian artery causes coronary subclavian steal syndrome (CSSS). We describe two patients who were diagnosed with CSSS following CABG. Patient A presented with angina pectoris, was diagnosed with CSSS and treated by transposition of the proximal IMA from the subclavian artery to the aorta. Patient B was diagnosed with CSSS by control angiography. Myocardial scintigraphy showed reversible silent ischemia. He was offered treatment, but refused as he was symptom-free.
