Use of radial artery as a graft for coronary artery revascularization was first proposed by Carpentier and associates in 1973 but soon abandoned because of its tendency to spasm 1 . The clinical application of the radial artery was not established until 1992, when Acar and colleagues reported a series of 104 patients who underwent radial artery grafting with an angiographic early radial graft patency rate of 93.5%2 . These improved results were attributed to the appropriate use of pharmacological antispasm agent such as calcium channel blocker. An arterial graft more closely approximates the diameter of the coronary artery; for an equivalent flow volume, blood velocity is greater than for vein grafts, which may reduce stasis.
