Interventional treatment of the left subclavian in 2 patients with coronary steal syndrome

Figure 1 Reverse blood flow was observed from the left artery disease to the left internal mammary artery graft. During coronary angiography (red arrows in A and B) despite 75% stenosis of the left main coronary artery (orange arrow in A), contrast injection could be followed up to the insertion of the graft in the subclavian artery (red arrow in C). Angiography of the subclavian artery revealed high grade lesions in the subclavian and left vertebral artery (orange arrows in D).
