May inform surgical options in coronary-subclavian steal syndrome; hypothesis-generating from single-case evidence.
Reverse flow in the internal mammary artery coronary graft in the presence of subclavian stenosis is rare. We describe a 67-year-old man who 7 years after coronary artery surgery was admitted with left subclavian artery stenosis and retrograde flow in the pedicled left internal mammary artery graft. Subsequent redo triple coronary artery bypass grafts included regrafting the left internal mammary artery graft to a new vein conduit.
