The summary: Background: To improve the patency rate of radial artery grafts, we have been using A skeletonized harvesting technique since 09/01/2000. Our early reports confirmed better graft patency of skeletonized radial graft compared to conventional pedicled grafts. Off-pump coronary artery bypass has been increasing in our institution. Here, we present our angiographic and clinical follow-up data on skeletonized radial artery grafting, exclusively among those who underwent off-pump bypass.
Methods: Between September, 2000 and July, 2002, a total of 247 patients underwent isolated off-pump coronary artery bypass using skeletonized radial artery graft, excluding T-grafting. Of these, 152 (61.5%) underwent postoperative angiography, and their perioperative, early angiographic, and follow-up results were analyzed.
Results: There was no hospital death and 5 incidences of postoperative myocardial infarction. None were related to radial artery bypass. Early angiographic control revealed that the stenosis-free graft patency rate of radial artery anastomoses (233/242, 97.9%) was not significantly different from other conduits (the left internal mammary artery 100%, right internal mammary artery 90.2%, gastroepiploic artery 98.4%, and saphenous vein 100%). Follow-up was completed all hospital survivors with a mean follow-up of 1.0 0.4 years. There were no cardiac deaths, myocardial infarction, or angina recurrence.
Conclusion: The angiographical patency of the skeletonized radial artery graft performed under off-pump technique was excellent. Although cardiac events were not observed so far, follow-up mid-term angiographies will be necessary to confirm our clinical outcome data.
