Key result
Endoscopic pedicle saphenous vein graft harvesting shows ~98% early patency without major wound complications.
Why the study?
No-touch SVG harvesting offers excellent long-term patency in CABG but causes more wound complications than conventional methods, prompting evaluation of an endoscopic pedicle harvesting approach.
Does endoscopic pedicle saphenous vein graft harvesting (Pedicle-EVH) prevent wound complications and maintain early patency in patients undergoing coronary artery bypass grafting?
Observational (n=72)
No
Does endoscopic pedicle saphenous vein graft harvesting (Pedicle-EVH) prevent wound complications and maintain early patency in patients undergoing coronary artery bypass grafting?
Endoscopic pedicle saphenous vein graft harvesting appears safe with no major wound complications and satisfactory early patency, though long-term outcomes require further monitoring.
May support Pedicle-EVH feasibility in CABG; leaves open long-term patency and randomized confirmation.
The excellent long-term patency of no-touch (NT) saphenous vein grafts (SVGs) makes the grafts very attractive for coronary artery bypass grafting; however, NT-SVG harvesting has a greater incidence of wound complications than conventional methods. Since 2009, we have performed endoscopic vein harvesting (EVH) in our department with very few major wound complications. Because NT-SVG harvesting is expected to provide long-term patency, if performed with EVH, the incidence of wound complications will be reduced. Thus, we began performing endoscopic pedicle SVG harvesting (Pedicle-EVH) in March 2019. Herein, we report the early results obtained using our current Pedicle-EVH procedure. No major wound complications were reported, and the early results, including patency, were satisfactory. To harvest the pedicle SVG, however, we used a different method than the NT-SVG procedure, so careful monitoring will be needed to assess long-term outcomes.

Katayama et al. (2023) conducted an observational in Coronary artery disease requiring coronary artery bypass grafting (n=72). Endoscopic pedicle saphenous vein graft harvesting (Pedicle-EVH) was evaluated on Early graft patency. Endoscopic pedicle saphenous vein graft harvesting in 72 patients resulted in 97.7% early graft patency and no major wound complications.
