膝关节置换术后下肢深静脉血栓形成的因素分析

Analysis of the Factors of Lower Extremity Deep Vein Thrombosis After Total Knee Arthroplasty

目的对可能造成膝关节置换术后下肢深静脉血栓形成的因素进行探讨和分析。方法根据我院2012年7月-2013年7月收治的124例膝关节置换术后发生下肢深静脉血栓情况的形成因素进行分析。利用彩超检查技术观察患者术后一周内深静脉动态情况，对各项可能影响因素进行记录。结果在全部124例膝关节置换术患者中，术后发生下肢深静脉血栓的患者有33例，占26.6%，未发生的患者有91例，占73.3%。60-70年龄段的患者、肥胖指数越高的患者以及女性患者，术后发生下肢深静脉血栓的可能性更大，组间比较差异有统计学意义（P〈0.05）。结论膝关节置换术后发生下肢深静脉血栓的患者中，女性比例高于男性，其中肥胖者、高龄患者更容易在术后发生下肢深静脉血栓。

Objective To discuss and analyze the possible factors of lower extremity deep venous thrombosis after total knee arthroplasty. Methods A total of 124 cases with deep venous thrombosis of lower extremity who were given knee arthroplasty in our hospital from July 2012 to July 2013 were analyzed. Then observed the dynamics situation of deep vein used by the ultrasound technology within one week after operation,and recorded the possible factors. Results Al the 124 cases of knee arthroplasty,33 postoperative patients had with deep venous thrombosis of lower extremity, accounted for 26.6%. The patients did not occur in 91 cases,accounting for 73.3%. The possibility of deep venous thrombosis after operation was higher in 60 - 70 age patients,higher BMI patients,and female patients.The difference between groups was significant,and had statistical significance（P〈0.05）. Conclusion According to the results of this research shows that the proportion of women is higher than men in the occurrence of lower extremity deep venous thrombosis after total knee arthroplasty,obesity and elderly patients are more likely to occur in deep venous thrombosis of lower extremity after operation.
