Figure 1. — Changes in coagulation markers in patients who underwent intermittent pneumatic compression only. Plasma levels of soluble fibrin (SF), plasminogen activator inhibitor type 1 (PAI-1), D-dimer, and thrombin-antithrombin complex (TAT) in patients who underwent intermittent pneumatic compression alone were measured preoperatively and on postoperative days 1 (PO1D), 3 (PO3D), 7 (PO7D), and 14 (PO14D). The boxes represent the interquartile ranges. The perpendicular lines (whiskers) represent the fifth and ninety-fifth percentiles and the horizontal bars in the boxes indicate the median values. On the day after surgery, the plasma levels of SF, PAI-1, and TAT were found to be increased in the venous thromboembolism (VTE) group compared to the non-VTE group. The changes in the D-dimer levels showed bimodal peaks on postoperative days 1 and 7 in both groups. Statistically significant differences were observed in the D-dimer levels measured on postoperative day 7. ^a p < 0.05 and ^b p < 0.01.
