Clinical observation of tempofilter Ⅱ inferior vena cava filter in the prevention of pulmonary embolism in patients with proximal deep-vein thrombosis

Objective The aim of this study was to evaluate our experience with the retrievable Tempofilter Ⅱ inferior vena cava (IVC ) filter with regard to insertion, efficiency, ease of retrieval, and any associated complications. Methods A retrospective review was performed of 112 patients (44 female,64 male,mean age 52. 3 years) who underwent Tempofilter Ⅱ IVC filter insertion. Filter insertion was successful in all patients. The filter was placed in via the jugular vein of 112 cases with acute deep vein thrombosis (DVT) and (or) PE;after drug treatment, it was observed whether there existed PE symptoms and if the change of the filter location occurred and associated complications. Results All the inferior vena cana filters were successfully emplaced,and DVT responded well to the filters;no clinical relevant pulmonary embolism occurred;The mean dwell time of successfully retrieved filters was 19. 3 days ( range 8-69 days). The thrombus was trapped in 54 cases (48. 2% ). One vena cana filter was escaped. Conclusion Tempofilter Ⅱ vena cana filter is of exact curative effect in the p revention of PE and high value of clinical application.     

临时性下腔静脉滤器预防肺动脉栓塞临床研究

目的 观察临时性下腔静脉滤器在预防肺动脉栓塞(PE)中的安全性和有效性.方法 112例经多谱勒超声证实存在下肢深静脉血栓形成(DVT)患者,给置入TempofilterⅡ临时性下腔静脉滤器,分析其使用的安全性及预防PE中的作用.结果 112例植入TempofilterⅡ临时性下腔静脉滤器的患者1例出现滤器脱出,54(48.2%)例发现滤器上拦截到血栓,在滤器置人期间没有发生PE.结论 Tempofilter Ⅱ下腔静脉滤器的置人能有效拦截缸栓,防止PE发乍.
