The changes of Caprini score, D-D and FIB levels in post-fracture DVT patients and their diagnostic significance / 临床外科杂志

ABSTRACT

Objective To investigate the changes of Caprini score, plasma D-D and FIB levels in patients with post-fracture DVT and its diagnostic significance.Methods Sixty patients with post-fracture DVT (DVT group) and 120 patients without DVT after fracture were selected (control group).The Caprini score, plasma D-D and FIB levels were compared between the two groups.The relationship between Caprini score and plasma D-D and FIB in the DVT group was analyzed.Results The Caprini score, D-D and FIB levels in the DVT group[7.26±1.88, (3.31±1.52) mg/L, (4.48±0.72) g/L] were significantly higher than those in the control group[3.39±0.80, (0.46±0.11) mg/L, (3.60±0.68) g/L], and the difference was statistically significant (P＜0.05).There was a significant positive correlation between Caprini score and D-D and FIB levels in patients with DVT (P＜0.05).There was a positive correlation between Caprini score and level of D-D and FIB (r=0.748、r=0.662, P＜0.05).The sensitivity of Caprini score combined with D-D and FIB levels in the diagnosis of DVT in fracture patients was 97.83％, specificity was 92.00％, missed diagnosis rate was 2.17％, misdiagnosis rate was 8.00, and area under ROC curve was 0.947 (P＜0.05).Conclusion Caprini score, D-D and FIB levels in patients with lower limb fracture have certain clinical value for the diagnosis of DVT.
