BACKGROUND: The radial artery has been used for coronary artery bypass grafting (CABG) but its early angiographic results were relatively inferior to that of the internal mammary artery, most likely due to spasm of the graft. To avoid vasospasm we harvested the radial artery using a skeletonized technique and spasm was completely reversed before use. The graft patency of the skeletonized radial artery was compared with the radial artery graft harvested as a pedicle. METHODS: A total of 112 patients underwent isolated CABG using a pedicled radial artery between September 1, 1999, and August 31, 2000 (group P), and a total of 131 patients with a skeletonized radial artery between September 1, 2000, and August 31, 2001 (group S). An ultrasonic scalpel (Harmonic Scalpel; Ethicon EndoSurgery, Cincinnati, OH) was used for skeletonization and removing satellite veins and surrounding tissue. CABG was performed by the standard technique. Perioperative results were prospectively collected and compared between the two groups. Early angiographic results performed within 3 months were also compared. RESULTS: There were two hospital deaths in group S. Major complications were observed in 11 (8.4%) in group S and 3 (2.7%) in group P (p = not significant [NS]). None were related to the radial artery graft. Angiography was obtained in 96 patients of group S and 76 patients in group P and revealed that the stenosis free graft patency rate of group S (138 of 143, 96.5%) was superior to that of group P (73 of 86, 84.9%) with p < 0.005. CONCLUSIONS: Skeletonization of the radial artery with the ultrasonic scalpel is safe and contributes to reducing the incidence of early graft stenosis.
