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.
