Abstract: Objective To study the application of coronary endarterectomy (CE) in coronary artery bypass graft (CABG), and to evaluate the effect of CE plus CABG on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods Thirty one patients, who underwent coronary endarterectomy in our institution between Oc-tober 2009 and October 2012, were reviewed retrospectively and compared the control group with 31 patients of their age, sex, LV function, and angina class. Results Among the 31 patients, 27 patients underwent one, 4 patient underwent two coronary arteries endarterectomized. Of all these 35 total endarterectomies, 13 (37%) were at left anterior descending artery, 3(9%) were at branches of the circumflex artery, and 19 (54%) involved the right coronary artery. There was no statistical dif-ference between two groups in clinical parameters including aorta cross time, cardiopulmonary bypass time, graft runoff, pul-sation index and mechanism ventilate time (P>0.05). There was no perioperative myocardial infarctions in CE group nor in control group. All patients were followed up and no recurrent angina were present in CE group. In CE group, one patient died of fungal pneumonia and heart failure half a year after operation. Conclusion In current cardiac surgical practice, coronary endarterectomy is an indispensable adjunct to CABG. The operative mortality and major morbidity were comparable or simi-lar to coronary artery bypass grafting, but its short-term and medium-term results were more favorable than to CABG.
