Lin et al reported a calcification score for patients with mesenteric venous calcification. The authors are from China Medical University Hospital, I-Shou University, University of California Irvine, University of California San Francisco and Asia University (Taiwan).
Patient selection: calcifications in mesenteric veins
Venous segments:
(1) ileocecal vein
(2) right colic vein
(3) middle colic vein
(4) left colic vein
(5) sigmoid vein
Calcifications
Points
none
0
limited to the straight vein
1
involvement of paracolic marginal vein
2
involvement of main branch, involving less than 50% of proximal length
3
involvement of main branch, involving the distal end
4
where:
• The straight veins drain the colon wall.
• The paracolic marginal vein drains the straight veins.
total score =
= SUM(points for all 5 venous segments)
Interpretation:
• minimum score: 0
• maximum score: 20
• The higher the score the more extensive the calcifications.
