The generation of reactive oxygen species in human saphenous vein (HSV) is increased after undergoing surgical vein graft preparation. Levels of reactive oxygen species were assessed by measuring by the conversion of dihydroxyethidium (DHE) to 2-hydroxyethidium. Levels of 2-hydroxyethidium were significantly greater in HSV obtained after ex vivo surgical vein graft preparation injury compared with HSV immediately following surgical vein graft harvest (n = 4; P = .03). *P < .05; **P < .01; and ***P < .001.
