RESULTS OF COMBINED ENDARTERECTOMY-ANGIOP LASTY IN CORONARY-ARTERY BYPASS GRAFTS

From January 1989 until April 1990, 472 consecutive patients were oper ated for coronary artery bypass grafting. The patients were classified into three different groups. In group I, 412 patients were operated w ithout endarterectomy. Group II consisted of 37 cases operated with en darterectomy-bypass to 41 vessels. Group III consisted of 23 cases of endarterectomy combined with patch-plasty-bypass to 24 vessels. The le ngth of the segment endarterectomized was 25 to 70 mm (mean 37.86 +/- 12.18 mm). Peri-operative myocardial infarction occurred in 19 cases i n group I (4.61 %), 6 cases in group II (16.21 %), and 3 cases in grou p III (13.04 %). The percentage of IABP utilization was 2.91 % in grou p I ; 10.81 % in group II ; 8.69 % in group III. The hospital mortalit y for group I, group Il and group III was 3.88%; 8.10% and 8.69%. Mean follow-up was 16.4 months for 72 % of patients. In 5 cases of group I (1.80 %), in 8 cases of group II (27.58 %) and in one case of group I II (5.55 %), myocardial infarction occurred in the late post-operative period. Late mortality was 1.44% for group I; 17.24% for group II and 5.55 % for group III. There was no statistically significant differen ce between groups II and III, but the late results of group III are pr obably better.
