Great saphenous vein (GSV) is the longest vein in the body originating from the dorsum of the foot at medial malleolus to the level of groin skin crease. It is one among the clinically significant superficial veins of the lower limb. Double or duplication of GSV is considered to be one of its rarest variant forms, which might be often mistaken with the accessory saphenous vein. The overall incidence of duplicated GSV is reported to be 1%. We report herein, a unilateral duplication of GSV with its morphological and clinical perspectives. The major clinical complication that is often encountered from its duplication is recurrent incompetence of the GSV, which predisposes varicosity. Therefore, a thorough knowledge of venous anatomy is important for clinicians and sonographers.
