Brief summary
The great saphenous vein still remains one of the most popular additional conduits among others because of the availability and ease of its open harvesting. All described methods of endoscopic venous harvesting are associated with "skeletonization" of an autovenous conduit . The scientific novelty of our work is that we propose to harvest a vein through one mini-incision with the help of Karl Storz endoscopic equipment and the Ligasure electrodissector with surrounding tissues without the use of carbon dioxide. Harvesting vein endoscopically, together with the surrounding tissues, makes it possible to reduce complication in the lower extremities and prolong the patency of the venous conduits by finding itself in the flap.
Interventions
A randomized study comparing two groups of vein harvesting methods for coronary artery bypass grafting (CABG): endoscopic harvest versus standard open techniques.
Materials: Three hundred patients listed for CABG
Procedures: The endoscopic vein harvesting in flap are performed using an endoscopic video installation Karl Storz. the surgeon performs a cross-section of the skin 3 to 4 cm long at the level of the knee joint. And vein harvest from the leg using retractor (Freiburg model (Karl Storz)

With the help of an electrical dissector, a tunnel is formed along the flap of a vein with a simultaneous harvesting of the flaps itself.
