Coronary Artery Surgery in Chronic Renal Failure (CRF) Patients

OBJECTIVE: Coronary artery surgery is described as high risk surgery in CRF patients. Volume and electrolyte imbalance are some of the reasons of increased risk in this group. In this study, our aim was to determine preooperative characteristics and to conclude early results of conventional coronary artery surgery in CRF patients.

MATERIAL and METHOD: 12 patients were included in the study. 10 of them needed routine hemodialysis and 2 of them needed short term dialysis programme at preoperative period. 9 patients were male and 3 were female. Mean age was 56.5±16.5 years. TTE and coronary angiography was performed for all patients preoperatively. An ultrafiltration apparatus added to arterial line and hemodialysis performed to all patients during cardiopulmonary by-pass (kg/15 cc)

FİNDİNGS: One patient was operated because of right atrial mass and single saphenous vein by-pass to Cx artery system was performed. 3 distal anastomosis was made in 7 patients and 4 distal anastomosis was made in 4 patients. Two of the patients not taking routine hemodialysis, during preoperative period did not need hemodialysis again. 2 of the patients died in first 10 days and one patient died at 18’th day due to sepsis. Mean intensive care unit time was 5.5±2.5 days.

RESULTS: Coronary artery disease is the most common reason of death in CRF patients. Rethrombosis rates are high after percutaneous coronary interventions in this group. Coronary artery bypass surgery must be preferred for better life expectancy with acceptable morbidity and mortality rates in CRF patients.
