OBJECTIVE: We evaluated the surgical outcome of coronary artery bypass grafting in dialysis patients. METHODS: We retrospectively analyzed 25 consecutive dialysis patients requiring isolated coronary artery bypass grafting. Their mean age was 61.6 years and average dialysis duration 80.4 months. RESULTS: Eight patients (32%) had emergency or urgent surgery. The mean number of bypassed vessels was 3.3 +/- 1.2. Internal thoracic artery grafts were used in 19 patients and gastroepiploic artery grafts in 5. Two (8%) died during hospitalization and complications occurred in 11 (44%). No cerebral complications were observed. All survivors showed ameliorated symptoms and improved overall function. Of 14 late deaths, 5 were cardiac-related, with 2 involving obvious myocardial ischemic events. Actuarial survival, including hospital deaths, at 1 year was 70.9%, at 3 years was 43.5%, and at 5 years was 34.8%. Cardiac-death-free survival was 70.2% at 3 years and 70.2% at 5 years. CONCLUSION: Coronary artery bypass grafting in dialysis patients is associated with a higher incidence of complications but has acceptable surgical mortality and effectively relieves angina symptoms.
