What are the lower veins called?
The two major superficial veins of the lower extremities are the great saphenous vein (GSV) and small saphenous vein (SSV). The terms “greater saphenous vein,” “long saphenous vein,” “lesser saphenous vein,” and “short saphenous vein” are no longer recommended for the purpose of standardizing terminology [10,11].
