Its clinical outcome is acceptable; however, the graft patency rate at 1 year has not been reported. </P><P>Methods: Between July 1, 2003, and October 31, 2002, 50 consecutive patients underwent isolated coronary artery bypass using skeletonized radial artery grafts in our hospital. There were no hospital deaths or perioperative myocardial infarctions. All patients completed follow-up by November 2003. Twenty of these patients (18 asymptomatic volunteers and 2 symptomatic patients) underwent coronary angiography at 1 year, and the results were analyzed. </P><P>Results: At a mean (±SD) follow-up period of 1.2 ± 0.2 years, there were no deaths. Two patients developed angina due to graft occlusion (1 in the radial artery and another in the gastroepiploic artery). Twenty-one radial artery grafts and 36 distal anastomoses with radial artery grafts were evaluated by angiography at 1 year (0.9 ± 0.1 years). There was 1 radial artery graft occlusion affecting 1 distal anastomosis, giving a perfect graft patency rate of 95.2% (20/21) and a perfect anastomosis patency rate of 97.2% (35/36). The patient with the occluded radial artery graft had a history of peripheral vascular disease and diabetes. There were no graft stenoses or string signs. </P><P>Conclusion: At our limited follow-up, the results of using skeletonized radial artery grafts are excellent. Extensive skeletonization will not affect the graft patency rate or early graft spasm. Careful examinations of the radial artery grafts in patients with a history of peripheral artery disease and diabetes are mandated.</P> ER -
