摘　　要：目的应用超声检查对下肢深静脉血栓脱落风险进行评估，为可回收下腔静脉滤器置入及回收提供重要的参考依据。方法选择64例下肢深静脉血栓患者，可回收下腔静脉滤器置入术前超声诊断报危急值的14例为高危组，未报危急值的50例为低危组。记录两组回收术中滤器内收集血栓情况，比较两组患者的血栓脱落率；下腔静脉滤器回收术前再行超声检查，将回收术前超声诊断结果与置入术前超声诊断结果比较，血栓有变化的17例称为变化组，血栓无变化的47例称为稳定组。记录两组回收术中滤器内收集血栓情况，比较两组患者的血栓脱落率。结果高危组14例回收术中可见10例滤器收集到血栓，血栓脱落率71．43％。低危组50例回收术中可见8例滤器收集到血栓，血栓脱落率16％，两组患者血栓脱落率比较差异有统计学意义（x^2=16．623，P〈0．05）。变化组17例回收术中可见12例滤器收集到血栓，血栓脱落率70．59％。稳定组47例回收术中可见6例滤器收集到血栓，血栓脱落率为12．77％。两组患者血栓脱落率比较差异有统计学意义（x^2=20．470，P〈O．05）。结论超声可以较准确地评估下肢深静脉血栓脱落的风险，为下腔静脉滤器!配入及回收提供重要参考依据，具有重要的临床价值。Objective To evaluate the possibility of deep vein thrombosis defluvium of lower limb using ultrasonography to provide important reference for the implantation and retrieve of retrievable inferior vena cave （IVC） filters. Methods Sixty-four patients who were diagnosed as lower limb deep vein thrombosis using ultrasonography were enrolled. Fourteen patients with critical values were allocated to high risk group,50 patients without critical value to low risk group. All the patients underwent inferior vena cava filter operation. Of all these paLients, ultrosonography were performed once again before IVC filters were retrieved. Seventeen patients with broken thrombosis were allocated to unstable group, 47 patients with stable thrombosis to stable group. Relationships between conditions of thrombosis and ultrasonography results were analysed. The conditions of thrombosis were recorded. The rates of thrombosis defluvium were compared. Results In high risk group,10 patients （71.43%） had thrombosis.In low risk group,8 patients （16%）had thrombosis. There were significant differences in the rates of thrombosis defluvium beteen the high risk group and low risk group（ P %0.05）. In unstable group, 12 patients （70.59%） had thrombosis. In stable group, 6 patients （12.77%） had thrombosis, there were significant differences in the rates of thrombosis defluvium between the unstable group and stable group （P 〈 0.05）. Conclusions Ultrasonography can be used to evaluate the possibility of lower extremity deep vein thrombosis defluvium which will guide the pratice of the retrievable inferior vena cava filter.
