Relationship between severity of venous calcifications and symptoms of phlebosclerotic colitis

Figure 1 Schematic figure for calculating calcification score. Calcifications (grey dots) at two straight veins, one marginal vein, and one main branch of mesenteric vein are noted. The proximal ends of main branches of mesenteric veins are not involved. Therefore, the calcification score in this case is calculated as 2 × 1 + 1 × 2 + 1 × 3 + 0 × 4 = 7.
