There are many kinds of graft could be utilized for coronary artery bypass grafting (CABG). The venous grafts that have been used are the saphenous vein, umbilical vein, cephalic vein, and homograft vein. On the other hand, the arterial conduits that now are accepted in coronary artery surgery are the internal mammary artery (IMA), right gastroepiploic artery (RGEA), inferior epigastric artery (TEA), and radial artery (RA). Using the arterial conduits as coronary artery bypass grafts becomes a new trend because of the arterial conduits are more free from vulnerability to atherosclerosis than the venous conduits, and the IMA is superior to the saphenous vein in the long-term patency rate hat! been proved also. The five-year patency rate of the radial artery grafts was elevating because of improved harvesting techniques and utilization of anti-spasmodic to prevention and management of spasm arterial grafts. The better patency rate led to the emergence of the radial artery as a graft in CABG again.
