This prospective, nonrandomized trial compared early outcomes of GSV harvesting by endoscopic technique versus open surgical technique. We divided them into two groups; EVH group (50) and OVH group (50).Both groups were similar with regard to; age, preoperative risk stratification, and risks for wound complication (diabetes, gender, obesity, preoperative anemia, hypoalbuminemia, low EF<40% and PVD).
