Long-term follow-up of the Vineberg internal mammary artery implant procedure.

This report describes the 20-year follow-up of a patient who had undergone a double internal mammary implantation for coronary occlusive disease. A lack of similar reports in the literature suggests that such survival is rare, but this case indeed documents the fact that the internal mammary arteries can revascularize the myocardium, and this patient's continued survival appears to depend entirely on this collateral blood flow.
