A group of 130 patients had aortocoronary bypass grafting using multiple sequential anastomoses to a single vein. Of the 122 operative survivors, 100 have had excellent results clinically. This has been confirmed angiographically in 24. The conditions of eight patients are unimproved and occlusion or partial occlusion of the venous bypass has been at fault in six. Thirteen patients are thought to have only a fair result because even though they have improved in regard to signs and symptoms of myocardial ischemia, they have not returned to an activity level that exceeds their level of accomplishment, preoperatively. The final evaluation of this operative technique will depend on the results of arteriographic studies done a year or more following operation.
