To determine the operative outcome of coronary artery bypass graft surgery (CABG) for severe coronary artery disease in long-term hemodialysis patients, we analyzed a group of 16 patients who underwent CABG over a ten-year period in our institution. Hospital mortality was 12.5% (2 of 16 patients). These two patients died of ischemic colitis and perioperative myocardial infarction, respectively. There were five late deaths: one patient died from myocardial infarction, one from uremia, one from gastro-intestinal bleeding, one from gastric cancer and one from unknown cause. There were four significant postoperative complications (morbidity 25%), consisted of one pulmonary tuberculosis, one sternal dehiscence secondary to mediastinitis, one mediastinal hematoma secondary to late bleeding from the LITA dissection area and one A-V shunt trouble. Graft patency rate within the first two months was 93% (30 to 42 in 13 patients). Hospital survivors experienced complete relief from angina. Actuarial survival was 68.8% at 3 years, 57.3% at 5 years and 28.6% at 7 years. This rate is not significantly different from the survival of all dialysis patients, but seems to be better than that of dialysis patients with not operated coronary artery disease. We concluded that CABG in dialysis patients can be accomplished with acceptable morbidity and mortality and effective relief of symptoms.
