A rare variation of deep femoral vein.

Venous pattern particularly in the lower limbs is of great clinical importance, while ligating the veins to prevent the spread of thrombus. Normally deep femoral vein drains the area supplied by profunda femoris artery, follows the pattern of branches of this artery and ends independently into the femoral vein. However in few cases it establishes communication with popliteal vein of femoral vein at a lower level. In the present study the deep femoral vein replaced most of the popliteal vein by establishing communication with the tibial veins.
