Long-term follow-up of sequential aortocoronary venous grafts.
In 1972 we reported myocardial revascularization of 130 patients using multiple sequential aortocoronary anastomoses to a single saphenous vein ]1]. Of the 122 survivors described in that report, 121 (99%) have been followed an additional 3 years. Twelve deaths occurred during the interval. The 110 currently followed patients represent 290 anastomoses; 54 have been studied angiographically since operation. Angiographic patency at 3 years in the studied group (18) was 70%. These figures exceed our follow-up data for 135 patients revascularized during the same period using individual vein grafts. Comparison of life table survival curves demonstrates this result. We believe the improved patency and decreased operating time that have resulted from employing this technique have outweighed the likelihood of a proximal stenosis causing closure of the whole graft system. We continue to use this technique in combination with internal mammary artery grafts in the management of multiple-vessel coronary disease. Good early results using this technique have been reported by other authors [2, 3, 5].
