Objective:To investigate the diagnostic value of albumin(Alb)to fibrinogen(FIB)ratio(AFR)in the forma-tion of deep vein thrombosis(DVT)of lower extremity after hip fracture in elderly patients.Methods:276 patients with hip fracture from February 2019 to May 2021 were selected as the research objects,multivariate Logistic regression analy-sis was used to analyze the risk factors for lower extremities DVT after hip fracture in elderly,receiver operating charac-teristic(ROC)curve was used to analyze the value of Alb,FIB and AFR in the diagnosis of lower limb DVT in elderly patients with hip fracture.Results:FIB level in DVT group was significantly increased compared with non-DVT group,Alb level and AFR level were significantly decreased,and the difference was statistically significant(P＜0.05).Multivariate Logistic regression analysis showed that FIB was a risk factor,Alb and AFR were both protective factors,and the differ-ence was statistically significant(P＜0.05).ROC curve showed that the area under curve(AUC)of FIB,Alb and AFR for the diagnosis of lower limb DVT after hip fracture in elderly patients was 0.727,0.665 and 0.815,respectively,and AFR had a higher diagnostic value for lower limb DVT after hip fracture in elderly patients.Conclusion:Increased FIB and decreased Alb are risk factors for lower limb DVT in elderly patients with hip fracture,and the value of AFR in diagnosing lower limb DVT in elderly patients with hip fracture is relatively high.
