Abstract OBJECTIVES: The standard of care regarding endoscopic vein harvesting (EVH) is still inhomogeneous across Europe. The current study aimed at elucidating patient-related factors favouring its application and procedure-related outcome in a tertiary care centre. METHODS: All patients who underwent coronary artery bypass grafting with or without concomitant valve procedures between 2008 and 2011 were included. Emergency surgery and all arterial revascularization patients were excluded. RESULTS: A total of 262 endoscopically harvested patients and 623 open vein harvested patients were included. Mortality, perfusion time and cross-clamp time were not significantly different. Peripheral artery disease predisposed open vein harvesting (odds ratio [OR] 1.9; P = 0.001); diabetes and a higher number of diseased coronary vessels favoured EVH (OR 0.6; P = 0.003 and 0.002). Further, the number of bypass grafts was significantly increased in the endoscopic group, but these patients required less periprocedural blood transfusions (1.4 ± 1.8 vs 1.8 ± 3.0; P = 0.035). Minor wound healing complications were more common in the open group (10.3 vs 3.8\%; P = 0.001). Severe complications in the leg requiring surgical revision occured in 2.4\% of open vein harvested patients compared with 1.1\% for endoscopic patients (P = ns). After a multivariate regression analysis, only female gender remained as a significant risk factor for impaired wound healing (OR 2.4; P = 0.001), whereas EVH reduced the risk of wound-healing complications (OR 0.4; P = 0.008). CONCLUSIONS: EVH dramatically reduced postoperative would healing complications. Women were more likely to develop mild and severe leg wound complications. Therefore, women may benefit even more from EVH. In general, the favourable outcomes of EVH should result in a more widespread use of this technology in men and women.
