It is affected by the life conditions causing pathological dilatations called varices. We observed bilaterally duplicated great saphenous vein in both lower limbs of an elderly male human cadaver during our routine dissection for undergraduate anatomy education. After a detailed inspection of the veins at both sides, we measured and illustrated the variant branches. In this case report, we presented bilaterally duplicated great saphenous veins, accompanied by an accessory saphenous vein. To the best of our knowledge, there are no such variations reported in the literature so far. We think that recognizing this and such variations before surgery will increase success. © 2021 Marmara University Press, All Rights Reserved.en10.5472/marumj.945178info:eu-repo/semantics/openAccessBilateral variationCadaverGreat saphenous veinagedarticlecadavercase reportclinical articledissectioneducationhumanhuman experimentlower limbmalesaphenous veinArticle342219221N/AWOS:0006575493000192-s2.0-85108460142Q4
