Abstract:Objective To analyze the value of thrombin time (TT), fibrinogen (FIB), and D-dimer (D-D) in the risk assessment of deep vein thrombosis (DVT) after secondary traumatic fracture. Methods A total of 100 patients with secondary traumatic fracture admitted to Ruikang Hospital Affiliated to Guangxi University of Traditional Chinese Medicine from January 2019 to July 2022 were selected and divided into DVT group (41 cases) and non-DVT group (59 cases) according to whether DVT occurred after operation. Univariate and multivariate logistic regression analysis were used to analyze the independent risk factors of postoperative DVT, and receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of TT, FIB, and D-D in postoperative DVT. Results TT in DVT group was lower than that in non-DVT group, FIB and D-D were higher than those in non-DVT group, and the differences were statistically significant (P<0.05). There was no significant difference in PT and APTT between the two groups (P>0.05). logistic regression analysis results showed that, general anesthesia (OR[95%CI]=2.194[1.626-2.960]), intraoperative blood transfusion (OR[95%CI]=2.458[1.780-3.394]), FIB (OR[95%CI]=1.483[1.244-1.768]), and D-D (OR[95%CI]= 2.026[1.610-2.549]) were independent risk factors for DVT after secondary traumatic fracture (P<0.05); TT (OR[95%CI]= 0.868[0.774-0.973]) was an independent protective factor for DVT after secondary traumatic fracture (P<0.05). The area under the curve predicted by the combination of TT, FIB and D-D was 0.914, the sensitivity was 0.927, and the specificity was 0.878. Conclusion TT, FIB, and D-D are independent influencing factors for DVT after secondary traumatic fracture, and the combination of these three factors can be used as a sensitive predictor of postoperative DVT.
