Abstract
Objective To discuss the risk factors of deep venous thrombosis (DVT) after the cesarean section.Methods The case group was composed of 55 patients with DVT within two weeks after the cesarean section from Jan,2002 to Mar,2012.The control group was composed of 110 patients without DVT after the cesarean section at the same time and in the same hospital.The general information including age,BMI,smoking history,drinking history and history of physical exercise and laboratory information including plasma D-D,CRP and PLT were analyzed by single factor methods.Besides,DVT were as dependent variable,and the relationship of DVT with the risk factors were analyzed with the multi factor logistic regression method.Results (1) Age,BMI,smoking,and the proportion of drinkers in the case group were higher than that in control group,the proportion of physical exercisers was lower than that in the control group,and the differences between the two groups have statistical significance (P ＜ 0.05) ; (2) CRP ＞ 10 mg/L and the plasma D-D ＞ 300 ng/ml proportion were higher in the case group than that in the control group,and the differences between the two groups have statistical significance (P ＜ 0.05) ; (3) The multi factor logistic regression analysis show that age,smoking history,CRP,plasma D-D and lack of physical exercise were the independent risk factors of lower limb DVT (P ＜0.05),OR (95％ CI) were 1.41 (1.10 ～1.80),1.84 (1.38 ～ 2.45) and 1.73 (1.40 ～ 2.13),1.75 (1.37 ～ 2.24) and 1.40 (1.11 ～ 1.77),respectively.Conclusion Age,smoking history,plasma D-D,CRP and lack of physical exercise may be the risk factors of lower limb deep venous thrombosis after cesarean section.关键词
