Abstract:
Objective To explore the risk factors of lower extremity deep venous thrombosis (LEDVT) of neurosurgical patients, and to provide references for identifying the most susceptible population and taking preventive measures. Methods A total of 68 cases of neurosurgical patients with LEDVT in three general hospitals from August 2010 to August 2013 were collected. The design method of one to one matching case-control study was used controlling age, sex and neurosurgical disease. Univariate and multivariate analyses were performed to determine the probable risk factors among two groups. Results The univariate analysis showed that coma, paralysis and limb immobilization, infection, trauma and fracture, lower limbs central venous catheterization, trachea cannula or tracheotomy, mechanical ventilation, surgical operation, dehydration and blood transfusion were significantly related to the incidence of LEDVT ( Χ2=4.50-33.23, P<0.05 or 0.01). The Logistic multivariate regression analysis showed that coma (OR=9.410, 95%CI 1.689-52.423), paralysis and limb immobilization (OR=4.950, 95%CI 1.432-17.105), infection (OR=2.927, 95%CI 1.162-7.373) and lower limbs central venous catheterization (OR=6.072, 95%CI 2.187-16.858) were independent risk factors for the development of LEDVT. Conclusions We should pay attention to patients with high risk factors of LEDVT and take preventive measures early to avert the formation of LEDVT.
