    Abstract:
    To improve the benefits from coronary artery grafting with internal mammary artery (IMA) several technical manoeuvres and methods have been developed to increase the number of coronary arteries and their branches that can be bypassed with internal mammary arteries. Between November 1985 and December 1986, 50 patients underwent a surgical myocardial revascularization procedure using both internal mammary arteries by single or sequential anastomoses and supplemental saphenous vein graft. In 42% of these patients complete revascularization was achieved employing only internal mammary artery grafts. One hundred and twenty-six internal mammary artery grafts (77% of the total coronary bypass performed), were placed. One patient developed perioperative myocardial infarction. Reparative surgery to control immediate post-operative bleeding was required in two patients. Post-operative coronary angiography performed in 30 patients showed all patent internal mammary artery grafts but one. No late deaths occurred. Mean follow-up of 10 months was complete in 50 patients, of whom 94% are symptom free. We conclude that bilateral internal mammary artery grafting can be performed with low operative risk and can provide excellent long-term functional improvement and survival employing only high patency arterial conduit. Moreover, it doesn't significantly increase surgical morbidity.
