The Venous Segmental Disease Score (VSDS) can be used to describe the extent of reflux and obstruction in the venous system of the lower extremities as demonstrated on imaging studies (such as phlebography or color duplex scan). This can be used for initial patient evaluation and for monitoring the venous disease over time.
Component scores:
(1) reflux score (reflux = incompetence in all valves in a venous segment)
(2) obstruction score (obstruction = EITHER total occlusion at some point in the segment OR > 50% narrowing for >= 50% of the segment)

Interpretation:
• minimum score for each: 0
• maximum score for each: 10
• The higher the scores, the more severe the venous disease.
