AbstractThis report reviews 218 patients who underwent internal mammary artery (IMA) grafting alone or with vein graft between 1986-1989. Our experience with IMA started with a single attached graft for proximal left anterior descending lesions in young patients affected from stable angina. After that our indications became more extensive. One IMA was utilized in 209 cases, both two IMAs in the remaining 9. Sequential IMA graft was performed in 16 patients and free IMA graft in 8. There were 242 IMA anastomosis and 295 associated vein by-passes. The overall operative mortality was 2.3%. Perioperative complications include myocardial infarction in 3 (1.4%), reoperation for bleeding in 4 (1.8%) and sternal wound complication in 4 (1.8%). These results are comparable to those of patients having only saphenous vein by-pass during the same period. At the follow-up actuarial survival rate at 42 months was 94 1.8% and 90% of these patients were completely asymptomatic. We include that IMA grafting shows low operative risk and provide excellent short term results. Our findings and the high long term patency rate of this conduit encourage us to extend the indication to IMA and to perform those surgical techniques that make possible multiple mammary coronary anastomosis.
