Résumé
Objective To investigate the risk factors and preventive strategies of patients with diffuse axonal injury(DAI) with deep veins thrombosis in lower limbs (LDVT).Methods One hundred and thirty cases of diffuse axonal injury patients with lower limb vascular were divided into LDVT group(22 cases) and non LDVT group(108 cases) based on ultrasound.The information including long-term bed,plasma fibrinogen level,varicose veins,hypertention,sex,age,smoking,alcohol drinking,diabetes,obesity,Glasgow Coma Scale (GCS) were collected.Results There were significant different between LDVT and non-LDVT group in terms of longterm bed time,hypertension,smoking,diabetes,high plasma fibrinogen,age,low GCS score correlated with LDVT (x2 =7.08,5.99,5.17,4.70,3.55,12.72,t =27.80,P ＜ 0.05).Gender,drinking,obesity,varicose vein factors had no correlation with LDVT(P ＞ 0.05).Conclusion Diffuse axonal injury in patients with LDVT is more common in patients with older age,hypertension,low GCS score,the higher the plasma fibrinogen.
