Start the longitudinal skin incision at the level where the great saphenous vein (GSV) terminates in the femoral vein. Expose the saphenofemoral junction step by step and divide its branches between simple ligatures. At the level where it terminates in the deep vein, divide the GSV over an applied clamp and secure the GSV stump with a suture ligature. Expose the GSV distad to the required length of the graft. Divide the GSV distally over an applied clamp likewise and secure it towards the periphery with a simple ligature. Mark the harvested GSV segment at one end with a coronary bulldog clamp (venous valves reversed) and place it in Bretschneider solution until further use. Once haemostasis has been achieved, close the wound in layers. Apply a dry dressing.
Tips:
1. Do not overstretch the harvested GSV segment, as this may result in sclerosis and stenosis in the long term.
2. The harvested GSV segment should be flushed with heparin-saline solution and thus gently stretched (not demonstrated in the video).
