Background: Off-pump coronary artery bypass surgery may provide an alternative form of surgical revascularization by avoiding the complications of cardiopulmonary bypass ( CPB). This study summarizes the midterm results of 136 off-pump bypass surgery patients. Methods: Between January 2000 and March 2002, out of 178 surgical myocardial revascularizations, 136 (76.4%) were off-pump bypass surgery. Complete revascularization was done and especially arterial grafts were used. All patients were followed clinically and with treadmill test for 2 years. Average control angiography was performed at the end of 2-year follow-up. Results: Of all the patients, 56.7% were male and the mean age of the patients was 63.6 ± 7.4 years. A total of 481 anastomoses were performed—136 (28.27%) to the left anterior descending artery ( LAD), 135 (28.07%) to the circumflex coronary artery ( Cx) branches, 102 (21.20%) to the right coronary artery ( RCA), 108 (22.46%) to the Dı. The mean graft number was 3.46. We used 96.6% of patients' left internal mammarian artery ( LITA), 29.2% radial artery (RA), 4.4% right internal thoracic artery ( RITA), and 100% saphenous vein. There were ischemic changes within 12 patients. All ischemic changes came back to normal within 4 and 18 hours, postoperatively. Mean extubation time was 5.36 ± 2.23 hours, mean stay in intensive care unit was 17.53 ± 3.15 hours, mean hospital stay was 5.03 ± 1.29 days. The LITA patency was 99.25%, RA patency was 97.84%, RITA patency was 100%, and saphenous vein patency was 91.79% with control angiography. Conclusion: Off-pump coronary artery bypass graft ( CABG) is efficient procedure with lower index of mortality, morbidity, ICU stay, hospital stay, good wound healing, early socialization, and results in lower costs.
