Abstract
Endoscopic vein harvesting(EVH) is being rapidly adopted as a routine surgical approach at many cardiac surgical centers worldwide. This rapid adoption of EVH is prompted by a dramatic reduction in invasiveness compared with traditional open vein harvesting(OVH) technique. Available evidence confirms two- and three-fold improvements in the rate of wound-related complications and infections for EVH. The significant reduction in incision length when grafts are harvested using EVH yields less wound-relatad pain thereby translating into increased patient satisfaction. Although the required disposable equipment costs are increased, shortened length of hospital stay, elimination of leg wound infections and a reduction in Non-infective wound healing disturbances(NIWHD) compared with OVH maintains the cost-effectiveness of EVH.
On the other hand, the association between this technique and poor graft patency has recently been called into question. Reassuringly, available evidence does not suggest that EVH is a poor method for harvesting vascular conduits. However, poor conduit quality, a consequence of the learning curve for EVH, has been shown to be a predictor of early graft failure.. There is a stronger need for adopting strategies aimed at minimizing the negative impact of learning curve on vein graft quality. Finally, our study results in addition to a lot of other previous studies confirm the benefits of EVH technique in reducing wound related complications and increasing patient satisfaction and cosmosis without affecting graft patency or causing damage to the harvested conduit. And it is expected that the OVH technique will be obsolete in a few years and that the EVH will be the standard used technique.
