Methods: Between January 2007 and July 2011, data of 30 patients (24 males, 6 females; mean age 64.7±8.3 years; range 43 to 83 years) with renal dysfunction who did not require hemodialysis and underwent coronary artery revascularization in our clinic were prospectively collected. Demographic data of the patients and preoperative and postoperative data were evaluated together with the clinical results.

Results: One vessel in 12 patients (40%) two vessels in 15 patients (50%), three vessels in two patients (6.6%) and four vessels in one patient (3.3%) were revascularized. The mean postoperative length of stay in the intensive care unit was 1.1±0.4 days, while the mean length of hospital stay was 7±3.2 days. The preoperative plasma creatinine and urea levels were 2.6±1.2 mg/dL and 70.9±28.7 mg/dL, respectively. The postoperative plasma creatinine and urea levels were 2.7±1.6 mg/dL and 73.7±38.7 mg/dL, respectively. There was no statistically significant difference between pre- and postoperative plasma creatinine levels. Hemodialysis was required in one patient (3.3%) in the early postoperative period. Four patients (13.3%) developed atrial fibrillation, while one patient (3.3%) had sternal detachment and mediastinitis. One patient (3.3%) died in the postoperative period.

Conclusion: The off-pump CABG can be safely done in patients with renal dysfunction requiring coronary artery revascularization with a lower mortality and morbidity rate.
