This is a retrospective study in OPCAB patients comparing patients who received skeletonized versus nonskeletonized SIMA and BIMA grafts. They reported patients with any sternal wound complication including redness or minor drainage that healed naturally. There was a lower incidence of complications in the skeletonized group as well as overall lower grade of complications. These effects were more pronounced in subgroup analysis of the BIMA group, including diabetics.
