目的:探讨经皮穿刺下腔静脉滤器置入术在治疗下肢深静脉血栓(DVT)中预防肺动脉栓塞(PE)的作用.方法:42例下肢深静脉血栓(DVT)患者,经股静脉途径放置下腔静脉滤器40例,2例经颈静脉途径放置下腔静脉滤器.结果:42例患者下腔静脉滤器置入成功率为100%,术中及术后均无严重并发症发生,复查滤器位置满意.结论:下腔静脉滤器置入预防肺栓塞是安全、有效的方法.“,”Objective: To investigate the role of percutaneous inferior venacava filter placement to prevent pulmonary embolism (PE) in the treatment ofdeep vein thrombosis (DVT). Methods: 40 in 42 cases with deep venousthrombosis (DVT) were placed through the femoral vein approach inferior venacava filter, 2 cases were placed inferior vena cava filter by the transjugular. Results:The success rate is 100% with 42 patients by inferior vena cava filter placement,and there were no serious complications occurred during and after surgery, it is satisfying to review filter position. Conclusion: The placement ofinferior vena cava filter is a safe, effective method to prevent pulmonary embolism.
