下腔静脉滤器预防肺动脉栓塞的应用价值

目的 讨论下腔静脉滤器放置术在下肢静脉血栓形成(DET)患者进行溶栓治疗中预防肺动脉栓塞(PE)的应用价值．方法 37例DET形成患者放置Greenfield下腔静脉滤器22个、Simon滤器12个、Bird—nestle滤器3个，放置后进行下肢静脉溶栓治疗，48h腹平片观察滤器的位置，1周后行彩色多普勒检查了解下腔静脉通畅度，出院后定期复查滤器位置．结果 滤器放置成功率为100％，溶栓过程中及追踪复查均未发生PE．结论 下腔静脉滤器放置术对PE的预防有较高的临床价值，下肢DET成患者行溶栓治疗前，作为常规应用可确保安全．

The Useful Value of Inferior Vena Caval Filter in Prevention of Pulmonary Arterial Embolism

Objective To discuss the clinical value of Inferior Vena Caval filter (IVCF) placement in preventing pulmonary embolism during the treatment of lower extremity deep venous thrombosis(DVT). Methods 22 Greenfield,12 Simon and 3 Bird-nestle IVCF were implanted in 37 patients with lower extremity DVT before the thrombolysis. The IVCF place was reviewed by plain film after 48 hour. The IVC was assessed by Dopler Utrasound after one week. Results The success rate of IVCF placement reached 100%. No pulmonary embolism occurred in all patients during thrombolysis and follow-up. Conclusions Due to it made the thrombolysis in the patients with lower extremity DVT more safely, IVCF placement is valuable for prevention of pulmonary embolism.
