Abstract
Duplex scanning was used to determine the presence of valvular incompetence in the major veins of 274 legs with venous disease. Using multivariate logistic regression analysis the significance of valvular function in each vein in relation to the clinical condition of the limb was calculated. Superficial femoral, profunda femoris and short saphenous vein function did not correlate with the clinical state of the limb; common femoral, popliteal and long saphenous vein function did. A table was constructed from the statistical model such that the relative contribution made by each vein could be estimated for limbs with different patterns of venous insufficiency. This model should now be tested in a prospective study and, if validated, could be used to improve decision making in venous surgery.
