Tel: +90 533 236 24 42 e-mail: sahinboz@yahoo.com ABSTRACT Objectives: The aim of the present study was to investigate the feasibility of revascularization of posterior wall coronary arteries with off-pump coronary artery bypass grafting (OP-CABG) versus conventional CABG (C-CABG). Patients and methods: Between July 2001 and October 2009, a total of 104 patients (26 males, 78 females; mean age 57±10.9 years; 43 to 74) who underwent CABG were included. The patients were divided into two groups as those undergoing revascularization with OP-CABG (Group 1, n=52) and those undergoing C-CABG. Intraoperative data and postoperative coronary angiograms at six months were recorded. Results: The OP-CABG was associated with less requirement for blood transfusion and a lower amount of postoperative drainage. Duration of intubation and the length of stay in the intensive care unit and hospital were found to be significantly shorter in the OP-CABG group. The patency of the arterial grafts was almost completely achieved in both groups, and anastomoses on the posterior vessels were patent in the OP-CABG group. Conclusion: Based on our experience, in properly selected cases, targeted vessels on the posterior wall can be successfully revascularized with OP-CABG.
