ResultsSeventeen patients with DVT after operation were discovered through Color Doppler ultrasonic detection, and all of the DVT occurred at the calf intermuscular vein.

方法纳入2007年2～7月48名患者51例全髋置换手术病例，术前和术后第7 d进行双下肢血管彩超检查，分析15项临床因素与术后下肢深静脉血栓的发生有无相关性。

Resultsseventeen patients with dvt after operation were discovered through color doppler ultrasonic detection, and all of the dvt occurred at the calf intermuscular vein. the incidence of the dvt in all patients was 33.3%, and 41.7% of these dvt patients were asymptomatic. logistic regression analysis indicated that patients older than 65(or=116.597), large volume of blood transfusion(or=1.01) and high level of triglycerides(or=37.249) were the risk factors for the occurrence of dvt after the tha.

结果经双下肢血管彩超检查，51例手术有17例发现dvt，全部为小腿肌间静脉血栓，dvt发生率33.3%；dvt患者中无症状者占47.1%(8/17)；多因素logistic回归分析表明：年龄≥65岁，输血总量大和血清甘油三脂水平高是全髋关节置换术后dvt发生的重要危险因素，其or值分别为：116.597、1.01和37.249(p.05)。
