经下腔静脉滤器间孔输入导管治疗肺栓塞11例分析

Inserting the catheter through inferior vena cava filter hole for the treatment of pulmonary embolism: analysis of 11 cases

目的：探讨经下腔静脉滤器（IVCF）间孔输入导管治疗肺栓塞（PE）的方法。方法2011年1月-2012年12月对11例PE患者先行IVCF置入，然后经滤器间孔输送导管进入肺动脉，经导管溶栓、碎栓、取栓等综合治疗，随访3～20个月，观察疗效。结果11例患者症状均即时改善，随访期间无PE加重及再次PE发生。结论对于急性PE患者，首先置入IVCF，然后经滤器间孔进行导管操作，方法安全且疗效肯定。

Objective To discuss the technique of insertion the catheter through the inferior vena cava filter （IVCF） hole for the treatment of pulmonary embolism. Methods During the period from Jan. 2011 to Dec. 2012 at authors’ hospital, the placement of IVCF was carried out in 11 patients with pulmonary embolism （PE）, which was followed by catheterization of pulmonary artery through IVCF hole to perform the catheter thrombolysis, thrombus-breaking, removal of thrombus, etc. All the patients were followed up for 3-20 months, and the clinical results were evaluated. Results After the treatment, the clinical symptoms were immediately improved in all patients. During the follow-up period, no deterioration of clinical symptoms or new pulmonary embolism occurred. Conclusion For the treatment of patients with acute pulmonary embolism, implantation of inferior vena cava filter followed by catheterization of pulmonary artery through IVCF hole to perform the procedure of catheter thrombolysis is safe with reliable therapeutic effect.（J Intervent Radiol, 2014, 23：296-298）.
