title: [Coronary endarterectomy].
abstract: From July, 1984, to December, 1986, coronary bypass grafting was performed in 314 patients, 70 (22%) requiring coronary endarterectomy (RCA; 48 pts, LAD; 10 pts, LAD + RCA; 10 pts, Others; 2 pts). Coronary endarterectomy patients (END group) were younger and often with the risk factor of hyperlipidemia than non-endarterectomy patients (NON group). The over-all hospital mortality rate of END group was 7 per cent; perioperative myocardial infarction occurred in 7 per cent of patients. Early postoperative angiogram (4 weeks after the operation) was performed in 54 patients. The patency rate of RCA endarterectomy was 81.8 per cent, and that of LCA endarterectomy was 75 per cent. This result was poor compared with the patency rate of non-endarterectomy graft (86.6%). However without endarterectomy, with all likelihood the patency rate of those grafts would have been poorer. The results of right coronary endarterectomy are satisfactory and better than those of the left coronary artery system. This experience suggests that coronary endarterectomy is safe and an useful adjunct of saphenous vein bypass grafting procedures in the management of diffuse coronary disease, especially in RCA lesions.
