Background: Single-inflow coronary bypass through left internal thoracic artery and Y graft is effective in myocardial revascularization, but left sublavian diseases may affect its safety.
Aim of the study: To assess that, in presence of a composite Y graft, issues involving the origin of the left internal thoracic artery are relatively easy to manage, even in reoperations.
Methods: A critical stenosis of the subclavian artery involving the origin of a bilateral internal thoracic artery Y graft was bypassed using a free radial artery graft.
Results: Bypass was performed between the left thoracic artery and the ascending aorta, off-pump and with excellent results.
Conclusions: In consideration of the excellent long term results of total arterial revascularization, radial artery is a feasible graft option, even in case of a composite Y graft in place.
Keywords: radial artery graft; redo coronary bypass; subclavian artery stenosis.
