Influence of graft anastomosis and graft morphology on long-term patency of the saphenous vein after aortocoronary bypass.

Objective: Several factors are involved in the preservation of graft function after surgical myocardial revascularization. This follow-up study aimed to evaluate the effects of vein graft anastomosis and graft morphology on long-term graft patency a minimum of 10 years after aortocoronary bypass grafting.Setting and Cohorts.
