“…Despite the above advantages, there are concerns regarding the detrimental effect on vein endothelium because of stretching and pulling, and promoting thrombosis, thus leading to early graft closure. 57,58 Nevertheless, endo vein harvest is associated with less readmission, antibiotic use, wound care, and need for surgical intervention, and should be promoted over the open vein harvesting technique.…”

Coronary artery bypass grafting is a commonly performed surgery worldwide that gives good results. Great saphenous vein is used as a conduit for bypass in over 95% cases. The harvesting technique has remained unchanged over the years. However, wound complications from harvesting the great saphenous vein by open method can be a major source of postoperative morbidity. With the objective of preventing major complications, identification of risk factors for saphenous vein harvest site infection is important. It is imperative to develop approaches that prevent infection and to allow for early recognition of patients who are at high risk and who may need more watchful monitoring so as to prevent development of wound complications. It is desirable to assess the patient completely, delineate the anatomy of peripheral vessels particularly in a patient with associated peripheral vascular disease, identify the best site to perform the saphenous vein harvest incision, employ a meticulous surgical technique, recognize complications early, and start the recommended treatment without delay. The aim of this paper is to identify the risk factors for saphenous vein harvest site complications and their identification, prevention, and management.

“…One major limitation of the current literature is that there is very little conclusive data regarding long-term patency rates of endoscopically harvested veins. There are some concerns that endoscopic vein harvest could be connected with a detrimental effect on vein endothelium which could promote a thrombogenic environment leading to a decrease in graft patency (Rousou et al 15 and Zenati et al 16 ). In our study, we found a statistically significant difference between the EVH and OVH groups in terms of percentage of endothelial damage which was statistically significantly higher in the EVH group.…”

“…Despite these studies, however, there is a paucity of data on the mid-term and long-term results. Also the histological data published in the literature have given rise to a mixed opinion 7,8 . The aim of this study was to examine local outcomes with endoscopic vein harvest (EVH) and to provide more data on the histological comparison of the veins after endoscopic and open harvest.…”

Aims. The aim of this study was to compare coronary artery bypass grafting (CABG) using either endoscopic (EVH) or open harvest (OVH). Leg-related morbidity and histological comparison of the veins were the outcome measures. Methods. One hundred consecutive patients scheduled for isolated CABG were randomly divided into two goups: an EVH and OVH group. Perioperative data were recorded. Patients were examined 7 days and 1 month postoperatively for leg-related morbidity. Samples for histological examination were taken from each harvested vein during the surgery. Results. Postoperative pain was statistically significantly lower in the EVH group 7 days postoperatively but the incidence of haematoma was non statistically higher in the EVH group while swelling was higher in the OVH group. Almost 40% of all histological samples were described as showing endothelial damage. There was significantly more endothelial damage in the EVH than the OVH group. Conclusions. We confirmed the advantage of EVH in terms of leg-related morbidity as well as cosmetic effect. This method however, was associated with more acute endothelial damage of the graft. These results support concerns that endoscopic vein harvest may be connected with detrimental effects on vein endothelium which could promote a thrombogenic environment leading to a decrease in graft patency. This could be extremely important. The results suggest that further investigation of the long-term patency of vein grafts harvested endoscopically is required.

“…In addition, early vein graft failure is associated with increased perioperative myocardial infarction [10,61], which consequently affects survival after CABG [58,59]. Several potential explanations exist for the recently chronicled poor performance of RSVG as aorto-coronary conduits including early technical errors, endothelial injury, and early thrombosis, which may be related to insufficient biologic reaction to aspirin or inadequate antiplatelet effect of aspirin [62][63][64]. One important contributor to poor RSVG conduit performance, receiving significant recent attention, may be the practice of harvesting the conduit endoscopically (EVH).…”
