    Abstract:
    BACKGROUND: Diabetes mellitus is an established risk factor for leg wound healing complications after great saphenous vein harvest. Leg healing complications occur in 1-25% of coronary artery bypass graft patients, and are often underestimated. PATIENTS AND METHODS: The records of 230 patients enrolled in a prospective trial to evaluate a minimally invasive approach compared with conventional longitudinal harvest were reviewed. Of 100 patients with diabetes, 49 had undergone minimally invasive harvest (group A). Forty-nine patients from the pool without diabetes who underwent minimally invasive harvest were selected using propensity scoring analysis (group B), and 46 diabetic patients operated using a conventional technique (group C) were matched to group A patients. Ninety-five patients with and 49 without diabetes finally entered the study. The quality of leg wound healing was quantified by ASEPSIS score by two independent surgeons in a blinded manner. The occurrence of complications was compared between groups. RESULTS: Fewer leg wound healing complications occurred in diabetic patients in the minimally invasive compared with the conventional group (P < 0.0001). Rates of complications were comparable among diabetic and non-diabetic patients operated using the minimally invasive technique. The intraoperative flow of vein grafts obtained by the minimally invasive technique was comparable to that of veins harvested using the conventional technique. CONCLUSION: These data suggest that postoperative leg wound morbidity can be significantly attenuated by the adoption of a less invasive approach, even in high-risk patients with diabetes. The advantages are not offset by the co-existence of other cardiovascular risk factors or by a long history of diabetes.
