Out of 2 638 patients undergoing coronary bypass surgery at the Arnault Tzanck Centre from 1973 to September 1984, 305 (12%) also required coronary endarterectomy. One hundred and eleven of these patients had control angiographies at the Centre and were the object of this study. Endarterectomy was carried out on a totally occluded artery in 38% of cases and was performed out of necessity in the other cases. One hundred and twenty-nine disobliterations were performed in these 111 patients. The average number of bypass grafts per patient was 2.8. The overall hospital mortality was 6% (19 out of 305) which was higher than for bypass surgery alone. The postoperative myocardial infarction rate was 10%. The 117 control angiographies were performed on average during the 8th month after surgery; these controls were routine in 99 cases (84.5%) in Stage I of the NYHA classification and for recurrent angina in 18 cases (15.5%). The endarterectomised vessel was patent in 72% of cases, which was less than the patency rate of the bypass grafts. Considering the indications of necessity, this result is satisfactory and is compared which those of other reported series.
