Skeletonization is an advanced technique of graft harvesting for coronary artery bypass grafting (CABG), and while it requires meticulous attention, it has many advantages. For example, skeletonization of internal thoracic artery (ITA) can minimize sternal ischemia and lower the risk of mediastinitis, and is longer and larger than pedicled ITA. In this article we describe the surgical techniques demonstrated in our video, which details our techniques of skeletonization of arterial grafts and off-pump coronary artery bypass (OPCAB) exclusively using these in situ grafts. Our method of right gastroepiploic artery (GEA) skeletonization has only three technical steps. The first step is to pass thin vessel loops under the GEA. The second step is to unroof the tissue surrounding the GEA. The last step is to seal and sever all the branches. Skeletonization of the GEA not only prevents vasospasm but also leads to GEA dilatation, and facilitates inspection and makes sequential anastomosis easier. Bilateral use of the skeletonized ITA and use of the skeletonized GEA can cover most coronary artery target sites without any manipulation of the ascending aorta. In our consecutive series of over 1,000 patients, the stroke rate was 0.5
