Abstract
A 77-year-old male former smoker with hypercholesterolemia and diabetes, who underwent coronary artery bypass graft surgery three years before admission and right carotid endarterectomy four years before admission, presented with recent-onset exertional chest pain. His medical history revealed that the chest pain was preceded by gradually worsening exertional claudication pain in his left arm when he was using crutches. The chest pain was similar to the pain he experienced before the coronary artery bypass graft surgery was performed. Coronary angiography and bypass graft imaging showed significant stenosis of the left subclavian artery proximal to the origin of the left internal mammary artery bypass, decreased flow in the left internal mammary artery with partial retrograde filling from the left anterior descending artery, and severe narrowing of the left vertebral artery with preserved centrifugal flow. Percutaneous stent implantation into the left subclavian artery was performed together with proximal balloon angioplasty of the left vertebral artery. The patient has been symptom free since the stent implantation.
