AN ANATOMICAL VARIATION OF GREAT SAPHENOUS VEIN : A RARE CASE REPORT

Abstract

The longest vein in the body and a superficial vein of the leg is called the great saphenous vein (GSV, also known as the "long saphenous vein"). Blood is being brought back from the foot, leg, and thigh to the deep femoral vein at the saphenofemoral Junction along the length of the lower limb. The clinical significance of GSV has gained interest in its anatomical variations. The variant vein and GSV are frequently confused because of their extensive tributary system. The two clinically significant structural variations of the GSV that are commonly used interchangeably are duplication and persistence of accessory GSV. GSV in this case, we found a duplicate GSV that originates from the lower one-third of the leg region, and both veins are of even calibres, which before drain into the femoral vein reunites to form a single vein. Finding such variations of the duplicate GSV, which is a rare variation of the GSV, is difficult from a therapeutic and diagnostic perspective, especially in venography procedures where it could cause iatrogenic traumatic injury to the vessel.
