Bjorgell and Robertson developed a scoring system for describing the extent of venous thrombosis in the lower extremity. The authors are from Malmo University in Sweden.
Venous segments:
(1) inferior caval vein
(2) common iliac vein
(3) external iliac vein
(4) internal iliac vein
(5) common femoral vein
(6) deep femoral vein
(7) superficial femoral vein
(8) popliteal vein
(9) anterior tibial vein
(10) posterior tibial vein
(11) fibular veins
(12) soleus vein
(13) gastrocnemius vein
(14) plantar pedis
Extent of Thrombus Along the Length of the Venous Segment
Points
none
0
less than one third of length
1
one third to less than two thirds
2
two thirds to entire length
3
where:
• A paired or double vein is defined as one segment.
total score =
= SUM(points for all 14 venous segments)
subscore A =
= SUM(points for 1,2, 3 and 4)
subscore B =
= SUM(points for 5, 6, 7, and 8)
subscore C =
= SUM(points for 9, 10, and 11)
subscore D =
= SUM(points for 12, 13 and 14)
Interpretation:
• minimum score: 0
• maximum score: 42
• The higher the score the more extensive the venous thrombosis in the lower limb,
