The great saphenous vein (GSV) is the longest superficial vein in the body extending from the medial malleolus to groin skin crease level. The clinical usage of GSV has made its anatomical variations noteworthy. Since many tributaries accompany it, GSV is often mistaken with the variant vein. Duplication and persistence of accessory GSV are the two major clinically significant anatomical variations of the GSV which is frequently misinterpreted as a synonym. In the present case, we report a unique variation of GSV wherein it bifurcated into anterior and posterior divisions of two uneven calibers at knee region, which then reunited at thigh region to form a single vein before its termination into the femoral vein. Locating such variations of bifurcated GSV is a challenging task for both diagnostic and therapeutic tactics, particularly in venography procedures as it might lead to iatrogenic traumatic injury of the vessel.
大隐静脉（GSV）是人体最长的浅静脉，从内踝延伸至腹股沟皮肤皱褶水平。GSV的临床应用使其解剖变异值得关注。由于有许多分支伴随，GSV常与变异静脉混淆。副大隐静脉的重复和持续存在是GSV两个主要的具有临床意义的解剖变异，它们常被误解为同义词。在本病例中，我们报告了一种独特的GSV变异，即在膝关节区域它分叉为两个管径不均的前支和后支，然后在大腿区域重新汇合形成一条单一静脉，最后汇入股静脉。对于诊断和治疗策略而言，定位这种分叉的GSV变异是一项具有挑战性的任务，尤其是在静脉造影过程中，因为这可能导致血管的医源性创伤性损伤。
