Why the study?
Coronary subclavian steal syndrome is a rare, mostly unrecognized and underdiagnosed disorder occurring after CABG using LIMA-LAD graft causing retrograde blood flow diversion from native coronary artery to subclavian artery.

Highlights the critical importance of evaluating for subclavian artery stenosis via inter-arm blood pressure differences in post-CABG (LIMA) patients who develop angina during hemodialysis via an ipsilateral AV fistula.
Coronary subclavian steal syndrome is a rare disorder, mostly unrecognized and under diagnosed, seen in patients developing subclavian artery (SA) stenosis after Coronary Artery Bypass Graft (CABG) using the LIMA-LAD graft diverting blood flow from the native coronary LAD back to the graft LIMA-LAD into the subclavian artery in a retrograde fashion. This is also the same for the vertebral artery where blood is diverted back from the brain into the subclavian artery.
