Bridge saphenous vein graft.


Single aorta-coronary artery vein grafts (bridge grafts) were constructed to two coronary branches with a side-to-side anastomosis in 250 patients. Most of these grafts were constructed between circumflex branches (96 grafts), circumflex and diagnol branches (47 grafts), and anterior descending and diagonol branches (79 grafts). The aim of the bridge graft is to decrease the number of anastomoses, decrease the operative time, and improve graft patency. The hospital mortality rate in this group of patients was 1.2 per cent, and the incidence of postoperative myocardial infarction was 3.6 per cent. One hundred ten patients were restudied after surgery; the average time of restudy was 1 year. Ninety-two grafts of 83.6 per cent had two anastomosis patent; 6 grafts (5.4 per cent) had one anastomosis patent; and in 12 grafts (10.9 per cent), both anastomoses were occluded. One hundred twenty-six associated grafts were studied all the same time; the patency rate was 84.1 per cent. From this experience, we believe the bridge graft is a useful procedure for bypassing the small coronary artery branches.
