The authors analyse 165 patients out of 359 submitted to myocardial revascularization during the period between January 1995 and January 1996, in which the saphenous veins and the internal thoracic arteries have been used as a sequential graft, or associated with a composit graft; 132 received saphenous veins as a sequential graft to two or more coronary branches, 25 had sequential anastomosis of the left internal thoracic artery to IVA and diagonal branches of the left coronary artery, and 8 cases had both saphenous veins and internal thoracic arteries used as a composite graft to branches of the left and right coronary arteries. In 96% of the cases the scheduled surgery was performed, one patient died in the immediate post-operative period (0.6%) and the morbidity was not different from that found in the standard coronary artery surgery. Details of the preparation of the grafts, as well as operative technique is discussed, and the results of this series stimulated us for further use of the sequential grafts aiming for complete myocardial revascularization.
