可回收型下腔静脉滤器的临床应用

Clinical application of retrievable inferior vena cava filter

目的评价置入可回收型下腔静脉滤器预防因下肢静脉血栓脱落引起肺栓塞(pulmonary embolism,PE)的有效性和安全性。方法 23例下肢深静脉血栓(deep venous thrombosis,DVT)患者置入可回收型下腔静脉滤器,并采用抗凝、溶栓治疗,临床观察是否出现肺栓塞症状和体征。结果可回收型下腔静脉滤器全部置入成功,下肢深静脉血栓患者经治疗后症状和体征缓解,无肺栓塞发生。置入滤器后14天成功回收21例,其中11例滤器上有血栓附着。结论置入可回收型下腔静脉滤器在下肢静脉血栓形成患者治疗中是预防肺栓塞有效、安全的方法。

Objective To evaluate the effectiveness and safety of inserting an retrievable inferior vena cava filter to prevent the pulmonary embolism（PE） due to thrombus in the lower extremities.Methods A total of 23 patients with deep venous thrombosis（DVT） were placed retrievable inferior vena cava filter.After anticoagulation and fibrinolytic therapy,it was observed whether PE symptoms existed.Results All the inferior vena cana filters were successfully emplaced.After the therapy,symptoms of patients were obviously improved.No PE occurred,and filters were smoothly removed after 14 days in 21 patients.Emboluses were entrapped by filter in 11 patients.Conclusions Retrievable vena cana filter is safe and effective in the prevention of PE for patients with DVT.
