可回收式下腔静脉滤器预防肺栓塞临床效果分析

The clinical efficacy of retrievable inferior vena cave filter in prevention of pulmonary embolism

目的评价可回收式下腔静脉滤器(IVCF)在预防下肢深静脉血栓(DVT)导致肺栓塞中的的临床作用。方法46例下肢深静脉血栓形成患者为预防肺栓塞置入可回收式下腔静脉滤器,随访观察无滤器并发症发生及肺栓塞的出现。结果35例在放置12～14天取出,11例患者因滤器周围血栓形成,下腔静脉置管溶栓5～7天,5例血栓消失,滤器成功回收,另6例溶栓效果不佳,长期留置滤器。在取出的40例中,12例肉眼可见絮状血栓。结论下腔静脉滤器置入术能安全、有效预防肺栓塞,是治疗下肢深静脉血栓的重要方法之一。

Objective To evaluate the clinical effect of inferior vena cava filter （IVCF） placement in treatment of deep venous thrombosis of lower extremity （DVT） and prevention of pulmonary embolism（PE） Method 46 patients with deep venous thrombosis of low- er extremity （DVT） were placed retrievable inferior vena cave filter. The patients were followed up to monitor complications. Results All the filters were successfully placed in right position and no detectable PE was seen. Conclusion The IVCF is an effective and safe method in preventing pulmonary embolism, and it is one of the most important methods in treatment for DVT of lower extremity.
