[Coronary bypass surgery using the internal mammary artery: results and 2-year clinical follow-up in Belgian patients].
During the years 1984-1985, 867 coronary bypass operations were performed. The internal mammary artery was used in 471 patients (54.3%). Hospital mortality was 1.3%. Complications were mainly cardiac and respiratory. In the 160 Belgian patients a clinical follow-up study was performed. Mean follow-up was 28.9 +/- 7.3 months; 80% of patients had no symptoms; 6 patients (4%) underwent recatheterization because of new symptoms. In only one patient was the mammary graft occluded. During the follow-up period 5 patients died; this represents a late mortality of 3.4%. The advantages and disadvantages of venous grafts versus bypasses using the left internal mammary artery are discussed. In coronary artery bypass grafting the internal mammary artery should be used preferentially because of its resistance to atherosclerosis and excellent long-term patency.
