Multiple Skin Bridging for No-Touch Saphenous-Vein Grafts Harvesting Can Reduce Wound Morbidity.

Abstract

Reducing the leg wound morbidity is crucial for the patients undergoing coronary artery bypass grafting (CABG) with great saphenous vein (SV) grafts harvested by no-touch (NT) technique. This study was to summarize the experience of skin bridging technique for reducing wound morbidity and the influence of it on one-year bypass graft patency. According to skin bridging or not, harvesting times, graft length, number of bleeding branches, postoperative subjective perception assessment scale (ASEPSIS) scores and one-year patency rate were analyzed. From June 2018 to February 2019, 60 patients underwent CABG with SV grafts either with open-incision NT or skin bridging NT (30 in each group). There were no significant differences in age (71.4 ± 5.1 years vs. 68.9 ± 5.5 years) or graft length (23.3 ± 1.1 cm vs. 23.9 ± 1.3 cm) between the two groups. The bridging/NT group had a significantly longer harvest time (38.5 ± 4.9 min vs. 18.5 ± 2.6 min; P < 0.001) and a significantly greater number of bleeding branches (1.9 ± 1.2 vs. 0.8 ± 0.8; P < 0.001) than the open NT group. The open NT group had a significantly higher ASEPSIS score (23.8 ± 2.0 vs. 15.7 ± 2.6; P < 0.001). There was no significant difference in patency rate at one-year follow-up. Obtaining the SV by the combined NT/discontinuous skin bridging technique is a satisfactory method for patients who underwent CABG. This method has important clinical significance in reducing wound morbidity in the harvest of NT grafts.
