Introduction: Chronic kidney disease is associated with signifi cant cardiovascular morbidity and mortality. Cardiac surgery in patients undergoing dialysis is still challenging due to increased perioperative complication rates and mortality. The aim of this study is to document the outcomes of cardiac surgery in end stage renal disease patients and analyze the impact of perioperative management strategies. Patients and Methods: Nineteen patients with end-stage renal disease undergoing hemodialysis (n= 17) or peritoneal dialysis (n= 2) operated between January 2011 and November 2012 were studied retrospectively. Isolated coronary bypass, coronary bypass concomitant with mitral valve procedures or mitral and/or tricuspid valve surgery were performed. Postoperative variables, mortality and survival rates were studied. Results: The mean age of the patients was 56.32 ± 12.97 years. Male to female ratio was 10/9. The mean duration of preoperative hemodialysis was 4.07 ± 1.89 and peritoneal dialysis was 1.5 ± 0.7 years. Mean cross-clamp time was 57.63 ± 21.56 minutes and cardiopulmonary bypass time was 87.89 ± 24.66 minutes. Mean amount of ultrafi ltration performed intraoperatively was 1610.53 ± 607.26 mL. Three (15.8%) in-hospital mortalities were noted. The median follow-up was 16 months and survival rate was 84.2%. Conclusion: A well planned surgical strategy and perioperative medical management including the timing of pre and postoperative hemodialysis, use or avoidance of cardiopulmonary bypass and the use of intraoperative ultrafi ltration should be documented to decrease perioperative morbidity and mortality.
