We observed bilaterally duplicated great saphenousvein in both lower limbs of an elderly male human cadaver during our routine dissection for undergraduate anatomy education. Aftera detailed inspection of the veins at both sides, we measured and illustrated the variant branches. In this case report, we presentedbilaterally duplicated great saphenous veins, accompanied by an accessory saphenous vein. To the best of our knowledge, there are nosuch variations reported in the literature so far. We think that recognizing this and such variations before surgery will increase success.
