Objective To explore the risk factors of deep vein thrombosis (DVT)occurred after cesarean section.Methods Nineteen women undergoing the cesarean section and suffering from lower extremity DVT between January 2012 to May 201 5 in our hospital were selected as the observation group,and 56 patients delivered in the same way without lower limb DVT during the same period of time were chosen as the control group.Single factor and multi-factor Logistic regression analysis were conducted to find out the risk factors of DVT.Results Single factor Logistic regression analysis showed that age,body mass index (BMI),C-reactive protein (CRP), AT-Ⅲ,D-dimer (D-D),FIB,APTT,lack of physical exercises,history of hypertension,diabetes mellitus,blood clots and oral contraceptives were the risk factors for DVT. Multiple factors regression analysis showed that age,BMI,CRP,D-D,physical exercises were the independent risk factors for DVT.Conclusion The occurrence of DVT is closely related to age,BMI,CRP,D-D and physical exercises. For delivery women with high risks for DVT, lower extremity deep vein thrombosis testing should be conducted one week after surgery and postoperative nursing and preventive measures should be taken to lower the incidence of DVT.%目的：探讨剖宫产术后深静脉血栓形成(deep vein thrombosis,DVT)发生的危险因素。方法将2012年1月-2015年5月在产科病房进行剖宫产术并发生下肢 DVT 的产妇19例作为观察组,同时选取56例同年度、相同时间段行剖宫产术但未发生下肢 DVT 的产妇作为对照组。对与 DVT 发生有关的相关资料进行单因素及多因素 Logistic 回归分析。结果单因素 Logistic 回归分析表明年龄、体重指数(BMI)、C-反应蛋白(CRP)、抗凝血酶-Ⅲ(AT-Ⅲ)、D-二聚体(D-D)、纤维蛋白原(FIB)、活化部分凝血酶时间(APTT)、高血压病史、糖尿病史、血栓史、口服避孕药史、无体育锻炼为 DVT 的影响因素。多因素回归分析表明,年龄、BMI、CRP、D-D、体育锻炼为 DVT 的独立危险因素。结论DVT 的发生与年龄、BMI、CRP、D-D、体育锻炼有关,对有 DVT 高危因素的产妇应在术后1周内进行下肢深静脉检查,加强术后护理,采取相应预防措施,降低 DVT 的发生率。
