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.
