    Abstract:
    Reoperative coronary artery bypass operations are increasing in frequency. Consequently, an ever-increasing pool of patients now is being seen with need of coronary revascularization for repeated time. Four cases of second reoperation were retrospectively investigated. Until March 1999, 2,563 cases of isolated coronary artery bypass grafting were done at the Heart Institute of Japan, Tokyo Women's Medical University, Tokyo, Japan. Within those cases, 124 cases (4.8%) were reoperated. And among those 124 cases, 4 cases (3.2%) were secondly reoperated. There were one hospital death and two had a perioperative myocardial infarction. All of them needed intraaortic balloon pump support after operation. Three were discharged with relief of the symptoms. The average age at the primary operation was 51.1 years. All these cases, at the primary operation, no ITA graft was used. Two cases were incompletely revascularized, because of coronary arteries were ungraftable. Both at reoperation and at second reoperation, we are trying to make a complete revascularization by all arterial grafts. But because of limited number of arterial graft at repeated operation, all arterial complete revascularization is not done without difficulty. Therefore it is concluded that saphenous vein graft is still needed at repeated operation.
