Abstract
Minimally invasive endoscopic vein harvesting (EVH) was first reported in 1996 as an alternative to open vein harvesting (OVH). Making coronary artery bypass surgery a less invasive procedure, shortly after its introduction, it became the standard of care for conduit harvesting. When compared to the conventional technique, the incidence of site infections wound dehiscence, delayed healing, duration of hospitalization, and postoperative pain were markedly reduced.
Highlights
Reported first in 1996, endoscopic vein harvesting (EVH) emerged as an alternative approach to the open vein harvesting method (OVH) [1]
The inclusion and exclusion criteria were applied to PubMed, eleven studies met the criteria and were included for the analysis, including 47968 patients (21622 for EVH, and 26346 OVH)
The debate regarding the effectiveness of endoscopic vein harvesting over the open technique has been resolved, as endoscopic vein harvesting resulted in less wound healing complications, less donor site infections, less postoperative pain and noninferior outcomes for all-cause mortality, in-hospital death, and major adverse cardiac events compared to open vein harvesting
Summary
Reported first in 1996, endoscopic vein harvesting (EVH) emerged as an alternative approach to the open vein harvesting method (OVH) [1]. It was rendering coronary artery bypass grafting (CABG) a less invasiveprocedure. The updatefrom (ISMICS) in 2017 [3] recommended endoscopic-vein harvesting to reduce wound-related complications, including wound infection or cellulitis (class I, level A). EVH is shown to improve patient satisfaction and postoperative pain when compared with the OVH technique (class I, level A). Two major trials, PREVENT IV trial and the ROOBY trial [4,5] associated the increase of major adverse cardiac events and reduced graft patency rates with the endoscopic-vein harvesting technique. The objective of this review is to discuss endoscopic vein harvesting outcomes and its advantages and disadvantages in light of the recent literature
