[Clinical analysis of second CABG].
We performed 1,560 coronary artery bypass grafting (CABG) at National Cardiovascular Center between November 1977 and August 1993. Of those, 41 patients received second CABG, 2 pts. received third CABG and 97 pts. received percutaneous transluminal coronary angioplasties (PTCA). We conducted a retrospective analysis of these patients to determine whether a previous CABG or CABGs affects the results. The hospital death rate was 10% (4/41) for re CABG, 50% (1/2) for third CABG and 0% for PTCA. In second CABG, 3-year cardiac event free rate was 58-68%, and early graft patent rate for new native lesion was high (97%, 28/29). However, the rate was low in graft to the site of the vessel which had occluded within 3 months after first CABG (59%, 7/12). Emergent or urgent operations performed in 14 cases (34%). In PTCA for SVG lesion (33 pts.), 14 (42%) patients received re PTCA and 6 (18%) had second CABG. These data indicated that the results of second CABG were affected by timing of the operation and the site of grafting. We believed that re operation to early occlusion site within 3 months should be performed carefully and further investigation is warranted.
