Combined internal mammary artery graft for coronary artery revascularization.
Five patients with multiple-vessel coronary artery disease underwent isolated coronary artery bypass grafting with a technique involving both internal mammary arteries and a small piece of interposed saphenous vein. The combined internal mammary artery grafts were used for sequential grafting. A total of 20 anastomoses were performed (average number, 4 anastomoses per patient). There were no operative deaths. Postoperative complications included reoperation for bleeding in 1 patient and diaphragmatic dysfunction in another. Postoperative coronary angiography 2 days before discharge (mean time, 10 days postoperatively) revealed that all the sequential anastomoses with the combined IMA graft were patent. Exercise tolerance tests performed 3 and 11 months postoperatively indicated excellent results and no ischemia. Based on this experience, we conclude that this method appears promising for multivessel coronary artery bypass grafting.
