Abstract:
Objective:To investigate the risk factors for lower extremity deep vein thrombosis (DVT) in patients with bone trauma and their diagnostic efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 108 patients with bone trauma who were admitted to Affiliated Changzhou Second People′s Hospital of Nanjing Medical University from October 2023 to February 2024, including 61 males and 47 females, aged 17-96 years [(55.2±19.5)years]. Based on the results of color Doppler ultrasonography of lower extremities within 96 hours on admission, the patients were divided into DVT group ( n=58) and non-DVT group ( n=50). In DVT group, 42 patients developed lower extremity DVT within 7 days after trauma and the other 16 patients developed lower extremity DVT after 7 days. Basic clinical data including gender, age, body mass index (BMI), underlying diseases, cause of injury, site of fracture, surgery and admission Caprini score, and admission laboratory test indicators including routine coagulation indicators [prothrombin time (PT), international normalized ratio (INR), thrombin time (TT), activated partial thromboplastin time (APTT), fibrinogen (FBG) and D-dimer (D-D)] and four thrombosis indicators [plasma thrombin-antithrombin III complex (TAT), thrombomodulin (TM), tissue-type plasminogen activator-inhibitor 1 complex (tPAIC) and plasmin-alpha2-plasmin inhibitor complex (PIC)] were collected in the two groups. Univariate analysis and multivariate binary Logistic regression analysis were conducted to investigate the correlation between these indicators and incidence of lower extremity DVT in patients with bone trauma and determine the independent risk factors. Receiver operating characteristic (ROC) curve and area under the curve (AUC) of the relevant risk factors were analyzed to evaluate and compare the diagnostic efficacy of the factors for lower extremity DVT in patients with bone trauma and further assess the diagnostic efficacy of the factors for lower extremity DVT within 7 days after bone trauma. Results:Univariate analysis revealed significant correlations of gender, age, Caprini score, D-D, TAT, TM and PIC with incidence of lower extremity DVT in patients with bone trauma ( P<0.01). The results of multivariate binary Logistic regression analysis demonstrated that Caprini score ( OR=1.36, 95% CI 1.12, 1.65, P<0.01), TAT ( OR=1.05, 95% CI 1.00, 1.10, P<0.05), and TM ( OR=1.34, 95% CI 1.02, 1.77, P<0.05) were significantly correlated to incidence of lower extremity DVT in patients with bone trauma. ROC curve analysis indicated that TAT (AUC=0.76, 95% CI 0.67, 0.86) had the highest diagnostic efficiency, followed by TM (AUC=0.72, 95% CI 0.62, 0.81) and Caprini score (AUC=0.72, 95% CI 0.62, 0.82). The combined analysis of all the factors effectively enhanced the diagnostic efficiency for DVT (AUC=0.84, 95% CI 0.77, 0.92). Additionally, TAT (AUC=0.81, 95% CI 0.71, 0.91) demonstrated better diagnostic efficacy for lower extremity DVT within 7 days after bone trauma compared with the Caprini score (AUC=0.72, 95% CI 0.61, 0.83) and TM (AUC=0.71, 95% CI 0.60, 0.83). Similarly, the combined analysis of all the factors also effectively enhanced the overall diagnostic efficacy for lower extremity DVT within 7 days after bone trauma (AUC=0.85, 95% CI 0.77, 0.93). Conclusions:Caprini score, TAT and TM are identified as independent risk factors for lower extremity DVT in patients with bone trauma, and all the three factors demonstrate good diagnostic efficacy. Their combination is found to have statistically significant higher diagnostic efficiency than each individual factor. Furthermore, TAT is proved to be the best in diagnosing lower extremity DVT within 7 days after bone trauma, while the combined analysis of all the risk factors can further improve the diagnostic efficacy.
