The following research examines the creation of a new small-diameter bypass graft. It is clinically relevant to patients who need distal arterial bypass, coronary artery bypass, or hemodialysis access, but who do not have adequate autologous vein for their surgeries. Future investigations will involve further tissue engineering of this vascular scaffold (eg, autologous endothelial seeding of its lumen) and testing the clinical usefulness of the completed graft.

The following is a case report of left breast necrosis following coronary artery bypass grafting (CABG) in a woman previously treated for a stage I breast carcinoma. To our knowledge this is the first such report of its kind in the literature. We believe that breast tumor extirpation and internal mammary artery utilization in combination are not sufficient insults on the vascularity of the breast to account for necrosis, but rather we feel that a variety of conditions are necessary for vascular compromise to occur.
