Veins assessed in the leg:
(1) pelvis and groin: iliacs, common femoral
(2) thigh and knee: superifical femoral, popliteal
(3) calf: anterior tibials, posterior tibials, peroneals

where:
• The soleal veins were not scored because of the variation in size and number.
Point assignment is based on the relative contribution to venous volume.
Total occlusion is defined as nonfillling of the vein.
The score is adjusted for partial occlusion. The points are assigned in proportion to the degree of involvement. There are several ways this could be assigned (volumetric vs two dimensional; linear vs nonlinear). The raw estimate of percent occlusion will be used in the implementation.
Interpretation:
• minimum score: 0
• maximum score for an leg: 40
• An increase in score after treatment indicates progression. A decrease indicates improved flow.
