Risk factors analysis of deep vein thrombosis in patients with hip fracture / 中国基层医药

ABSTRACT

Objective To analyze the characteristics and risk factors of preoperative deep vein thrombosis in patients with hip fracture,and provide a theoretical basis for clinical treatment and intervention.Methods 470 patients with hip fracture were chosen as the objects of study.The clinical data of the patients were retrospectively analyzed,including age,gender,injury,combined with other systemic diseases,fracture type (whether old fractures),two D-dimer level.All the patients with deep venous thrombosis of lower extremity were divided into DVT group and nonDVT group.There were 83 cases in DVT group,387 cases in non-DVT group.The factors like aboves as independent variables,presence of deep vein thrombosis as dependent variable,,preoperative deep venous thrombosis of the characteristics and risk factors were analyzed.Results 83 patients had DVT,the incidence rate was 17.7％.There were significant difference in age (40/83 vs 268/387),combined with other system diseases (57/83 vs 283/387),prevention measures (58/83 vs 196/387),D-thrombosis two dimer level (16/83 vs 122/387) of the two groups (x2 =13.712,14.836,9.876,5.313,all P ＜ 0.05).3 age ≥ 40 years,with other system diseases and injury,did not take to prevent the formation of thrombus measures were independent risk factors influencing the occurrence of DVT.Conclusion Age ≥40 years,combined with other system diseases and injury,don't take to prevent the formation of thrombus measures are independent risk factors influencing the occurrence of DVT.
