  • Title: Coronary steal from a left internal mammary artery coronary bypass graft by a left upper extremity arteriovenous hemodialysis fistula.

    Abstract:
    In patients with end-stage renal disease undergoing hemodialysis, the upper extremity arteriovenous (AV) fistula is the dialysis access recommended by the DOQI guidelines for patients with appropriate vasculature. Upper extremity AV fistulae have long periods of usefulness, high flow rates, and low associated complication rates. Placement of AV access may result in increased cardiac output and increased cardiac oxygen demand in these patients. In general, cardiovascular complications from AV access have been limited. We report a novel cardiovascular complication of AV access in an end-stage renal disease patient with a coronary artery bypass graft employing the left internal mammary artery who experienced angina while undergoing hemodialysis. The angina was mediated at least in part by cardiac catheterization laboratory-documented steal of blood flow from the internal mammary artery graft. This phenomenon suggests the need to consider the impact of upper extremity access placement on blood flow to the left internal mammary artery in patients who previously have undergone placement of a coronary artery bypass graft.
