A Randomized Comparison of Radial-Artery and Saphenous-Vein Coronary Bypass Grafts

Abstract

Radial-artery grafts are associated with a lower rate of graft occlusion at one year than are saphenous-vein grafts. Because the patency of radial-artery grafts depends on the severity of native-vessel stenosis, such grafts should preferentially be used for target vessels with high-grade lesions.
