Objective To analyze the risk factors of venous thromboembolism(VTE)after intracranial hemorrhage and establish an warning model.Methods 39 patients with VTE after neurosurgical intracranial hemorrhage in our hospital from January 2020 to February 2023 were col-lected as the observation group,and 39 patients without VTE after intracranial hemorrhage were randomly collected as the control group.The general information and clinical data were collected and compared.The high-risk factors affecting VTE were analyzed by logistic regression,and the efficiency of ROC curve was analyzed.Finally,the warning model was established.Results Univariate analysis showed that D-dimer levels and age in the observation group were significantly higher than those in the control group(P<0.05).And VTE after intracranial hemorrhage was related to the use of dehydrating agent,bed time,pelvic or lower limb fracture,muscle strength,central venous catheterization,increased muscle tension of lower limbs,operation and cardiovascular and cerebrovascular history.Multivariate logistic regression analysis showed that age≥60 years old(OR=5.417,95%CI:1.234～23.775),D-Dimer(OR=10.402,95%CI:2.081～52.001),muscle strength≤grade 3(OR=5.426,95%CI:1.314～24.083),pelvic or lower limb fracture(OR=6.901,95%CI:1.090～43.672),central venous catheterization(OR=4.489,95%CI:1.024～20.554),and cardiovascular and cerebrovascular history(OR=5.165,95%CI:1.020～26.166)were independent risk factors for VTE after intracranial hemorrhage(P<0.05).After rounding the values,an early warning model was established.The total score of the model was 36 points.After ROC curve effectiveness analysis,it was found that the score>14 points is a high risk.Conclusion The prediction accuracy of the VTE warning model after intracranial hemorrhage is good.Taking necessary preventive measures for patients with high risk score can reduce the incidence and mortality of VTE.
