[The causes and timing of reoperation for coronary artery disease].
In eight hundred and sixteen consecutive patients undergoing coronary artery bypass grafting (CABG) within the past 19 years (1974 to 1993), repeated CABG were performed on 12 patients (1.47%). The main reasons for repeated CABG were graft failure (GF), progression of native disease (NP) and incomplete revascularization (IR). The incidence of GF only and GF combined NP were high either within a half year or around 5 years after CABG. When the recurrence of angina is noted after CABG, the catheter intervention should be chosen at first but the reoperation should be done not so late. Although all patients survived from reoperation, three patients continued to have mild angina pectories. If a reoperation is inevitable, maximum utilization of arterial graft and accomplishment of complete revascularization are emphasized.
