The right gastroepiploic artery (RGEA) could be harvested easily and safely by using an ultrasonic scalpel. It is easier and faster not to remove a satellite vein from RGEA than to skeletonize it fully. And blood flow of the vein is important, because it is the flow of vasa vasorum of RGEA. Among 70 patients who have bypassed to right coronary arteries (RCA), 25 patients were treated with semi-skeletonized RGEA (SSK-RGEA), the other 45 patients were operated with pedicled RGEA or (if pedicled RGEA was short and small) with the other grafts. An availability of SSK-RGEA for RCA was 100%. And that of pedicled RGEA was 47% (p < 0.001). Twenty-eight patients were operated without a pump. Twenty-three of them (82%) were bypassed with RGEA. In the on-pump cases (42 patients), RGEA were used for 13 (31%) cases (p < 0.05). Early post-operative angiographies revealed 1 occlusion. But the site of occlusion was the origin of RGEA branch from a gastro-duodenal artery, and the anastomotic site was patent. This graft was supposed to be occluded post-operatively by arteriosclerosis. Flow competition occurred in two grafts. In conclusion, the SSK-RGEA was useful for RCA bypass grafting. The reliability of RGEA should increase the indication of off-pump coronary artery bypass grafting.
