Abstract 【Objective】To investigate the influencing factors of lower limb deep venous thrombosis(DVT) in patients with traumatic intracranial hemorrhage and the clinical value of Caprini score in predicting the occurrence of lower limb DVT. 【Methods】A total of 126 patients with traumatic intracranial hemorrhage admitted to our hospital from January 2020 to May 2023 were selected and divided into DVT group (n=35) and non-DVT group (n=91) according to the incidence of DVT in lower limbs. The influence factors of lower limb DVT were analyzed by univariate and multivariate Logistic regression equations, and the clinical value of Caprini score in predicting the occurrence of lower limb DVT was analyzed by receiver operating characteristic (ROC) curve. 【Results】The proportion of Caprini score, age≥60 and use of dehydrating drugs in the DVT group was higher than that in the non-DVT group, and the hospital stay was longer than that in non-DVT group, and the GCS score was lower than that in the non-DVT group,with statistical significance (P<0.05). Logistic multivariate regression analysis showed that GCS score, Caprini score, age, use of dehydrating drugs, and length of stay were all influencing factors for DVT of lower limbs in patients with traumatic intracranial hemorrhage (P<0.05). ROC curve analysis showed that the area under the curve (AUC) predicted by Caprini score was 0.805,95%CI was 0.662~0.801 (P<0.05), the sensitivity of prediction was 75.63%, the specificity is 66.21%, the positive predictive value was 49.2%,and the negative predictive value was 86.1%.【Conclusion】Age, length of stay, use of dehydrating agent, GCS score and Caprini score are all influencing factors for the occurrence of DVT in patients with traumatic intracranial hemorrhage. It is of great significance to take effective measures to prevent the occurrence of DVT in the lower extremity according to the influencing factors.
