Arnesen et al developed a scoring system for quantifying venous thrombosis in the leg based on the venographic appearance. The authors are from Ulleval Hospital in Oslo, Norway.
(1) anterior tibial
(2) posterior tibial
(1) percent of vein involved
(2) presence of absence of occlusion
1 - 33%
34 - 66%
67 - 100%
complete occlusion (no visualization)
total score for a lower extremity =
= SUM(points for all 6 veins)
• minimum score: 0
• maximum score: 30
• The higher the score the more severe the thrombosis.
• Instructions on how to grade a double venous segment are not given.
