A rare anatomical variation of the greater saphenous vein. Case report.

The venous system has frequent anatomical variations. A good understanding of the venous anatomy is very important and proper evaluation of the venous system is crucial for the appropriate treatment of venous disorders. There are many variations of the greater saphenous vein at the level of the thigh, knee and leg. All variations of the saphenofemoral junction reported in the literature refer to the drainage of the greater saphenous vein into the common femoral vein. A very rare greater saphenous vein variation at the level of the saphenofemoral junction is defined and discussed in this case report.
