Subclavian steal syndrome after coronary artery bypass graft surgery

Introduction: subclavian theft syndrome (SBS) is related to subclavian artery stenosis. In patients who were previously submitted to myocardial revascularization (CABG) surgery with internalcoronary mammary graft, SBS may trigger anginal symptoms.

Case Report: we report two cases of angina pectoris after CABG, associated with left upper limb pain on exertion. Patients were diagnosed with SBS and submitted to percutaneous transluminal angioplasty with stent implantation in the subclavian artery, evolving with clinical improvement.

Discussion: the reported cases are unusual in clinical practice and demonstrate the efficacy and safety of interventional
endovascular treatment in SBS.
