Effect of Skeletonization of the Internal Thoracic Artery for Coronary Revascularization on the Incidence of Sternal Wound Infection

Abstract

Use of the internal thoracic artery in coronary revascularization confers excellent benefit. We assessed the impact of skeletonization on the incidence of postoperative sternal wound infection in patients undergoing coronary artery bypass grafting. We also investigated whether there is an advantage in using this technique when harvesting both internal thoracic arteries in high-risk groups, such as diabetic patients. Skeletonization was associated with beneficial reduction in the odds ratio of sternal wound infection (odds ratio, 0.41; 95% confidence interval, 0.26 to 0.64). This effect was more evident when analyzing diabetic patients undergoing bilateral internal thoracic artery grafting (odds ratio, 0.19; 95% confidence interval, 0.10 to 0.34).
