INTRODUCTION
Coronary bypass grafting is well known surgical treatment method allowing to restore the coronary blood flow. Inadequate revascularization is the most important predictor factor for long-term outcomes in coronary bypass surgery (1). The LAD revascularization is the most important one in coronary vascularization. Coronary endarterectomy was first described by Bailey et al. in 1950 (2). Coronary endarterectomy was been performed on all presence of diffusely diseased coronary arteries that are not suised for distal grafting (3). Due to the deterioration of endothelial integrity after coronary endarterectomy, thrombus may develop in the early period and therefore, surgeons avoid endarterectomy. Acceptable clinical and angiographic results have been published (4).
