Saphenous vein harvest with the Mayo extraluminal dissector: Is endothelial function preserved? Michael R. Dashwood, PhD, Stephen Fremes, MD, MSc, Domingos S.R. Souza, MD, PhD The Journal of Thoracic and Cardiovascular Surgery Volume 139, Issue 1, Pages 239-241 (January 2010) DOI: 10.1016/j.jtcvs.2009.08.054 Copyright © 2010 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 Histology of saphenous veins in patients undergoing CABG. Transverse sections of saphenous vein harvested using the Mayo stripper (A), conventional preparation (B), and by the “no-touch” technique (C). The adventitia is damaged or removed using conventional methods and the Mayo stripper, whereas this layer remains intact using the “no-touch” technique (C). Also, the “no-touch” vein is surrounded by a cushion of fat (black staining). The arrows indicate the external elastic lamina, the media/adventitia border. Scale bar = 0.5 mm. (Part A was modified from Nowicki M, Buczkowski P, Miskowiak B, Konwerska B, Ostalsk-Nowiska D, Dyszkiewicz W.
