Impact of the Learning Curve for Endoscopic Vein Harvest on Conduit Quality and Early Graft Patency

摘要

BackgroundRecent studies have suggested that endoscopic vein harvest (EVH) compromises graft patency. To test whether the learning curve for EVH alters conduit integrity owing to increased trauma compared with an open harvest, we analyzed the quality and early patency of conduits procured by technicians with varying EVH experience.
