[Variability of the deep femoral venous system].

Deep venous system is known for its extreme variability but in anatomy it receives only marginal interest. Although a few previous anatomical studies have already pointed out the fact of a significant discrepancy between the autopsy findings and the literary description, it has not had any particular output so far. Our findings confirmed the deep femoral vein to be an alternative collateral vein connecting the popliteal with the femoral vein.
