[Re-operation for myocardial revascularisation. 15 cases (author's transl)]

Among 1110 patients undergoing aorto-coronary bypass procedures, 15 required late re-operation (average interval 28 months) for myocardial revascularisation. This was performed following the recurrence of anginal symptoms, on average 15 months after the first operation. Six resections of localised stenosis of the vein graft and eleven "new" aorto-coronary bypass were performed. One patient died early, 12 hours after surgery, while 2 died 3 and 26 months later. Nine of the 12 survivors had no symptoms 4 to 63 months after the re-operation. Thus in the presence of angina recurring after aorto-coronary bypass, a new follow-up coronary arteriogram should be performed in order to seek lesions which might benefit from further attempted surgical treatment.
