Endarterektomi Yapılan Atan Kalpte Koroner Baypas Cerrahisinin Uzun Dönem Sonuçları/Long-Term Results of Coronary Endarterectomy in Off-Pump Coronary Artery Bypass Surgery

The aim of the study was to review the late term results of coronary endarterectomy in off-pump coronary artery bypass graft surgery performed in our institution Between 1996 and 2006, 48 patients who underwent off-pump coronary artery bypass graft surgery and coronary endarterectomy were retrospectively studied. The mean age was 58,8±9,8 years. Twenty-four patients (50%) were Canadian Cardiovascular Society class III or IV. Twenty-eight patients (58%) had impaired left ventricular function. Sixteen patients (%33) had Type 2 Diabetes Mellitus. Twenty-nine patients (60%) underwent endarterectomy of left anterior descending artery and 17 patients (35%) underwent endarterectomy of right coronary artery. Seven patients (15%) underwent full arterial revascularization. The early mortality rate was 6,3% (n=3). Two patients (4.2%) suffered from postoperative myocardial infarction, and 2 patients (4.2%) required postoperative intra-aortic balloon pump counterpulsation. Mean intensive care unit stay was 2,29±1,27 days. Patients were extubated after a mean of 11±6 hours. The mean length of hospital stay was 9±6 days. Four patients (8,3%) had postoperative atrial fibrillation, and a mean of 1,21±1,35 units of blood were transfused postoperatively. There was three (%6,3) reopening for bleeding, and 4 (%8,3) patients required positive inotropic support. The median follow-up was 117±4,65 months, 85,5% of patients were angina free, and at the 27.2 ± 18,32 months follow up period 12 control coronary angiogram showed that 85% of total grafts were patent. Coronary endarterectomy in off-pump coronary artery bypass surgery can be performed with acceptable mortality and morbidity rates in diffuse coronary artery disease.
