The left internal mammary artery (LIMA) is frequently utilized in coronary artery bypass grafting (CABG); adequate visualization of the LIMA bypass graft during diagnostic angiography is critical for determination of myocardial blood supply. We present a novel case of angiography via a left transradial approach demonstrating an occluded LIMA coronary bypass graft with antegrade flow maintained via a collateral branch from the ipsilateral thyrocervical trunk. Given the prevalence of LIMA use in CABG, it is critical to be aware of unusual configurations, including collateralization of a proximally occluded LIMA graft as described in this report.
