Aegisy可回收腔静脉滤器的临床应用与观察

Clinical Application and Observation of Retrievable Aegisy Vena Cana Filter

目的探讨Aegisy可回收腔静脉滤器预防肺动脉栓塞的临床应用价值。方法对32例急性或亚急性下肢深静脉血栓形成(deep vein thrombosis,DVT)和(或)肺动脉栓塞(pulmonary embolism,PE)的患者经健侧股静脉置入滤器,经用药物或手术治疗,观察有无肺动脉栓塞症状及有无肺动脉栓塞症状加重情况,滤器有无形态及位置变化。结果下腔静脉滤器置入全部成功,下肢深静脉血栓形成患者治疗后效果良好,无症状性肺动脉栓塞发生,置入滤器平均(14.0±2.0)天,取出可回收滤器捕捉血栓24例,占75%。结论可回收下腔静脉滤器预防肺动脉栓塞的疗效确切,具有较高的临床应用价值。

Objective To discuss the clinical application value of retrievable Aegisy vena eana filter in the prevention of pulmonary embolism （PE）. Methods The filter was placed in via the healthy side femoral vein of 32 cases with acute or subacute deep vein thrombosis {DVT） and {or） PE; after drug or surgical treatment, it was observed whether there existed PE symptoms, whether the symptoms were aggravated, and if the change of the filter shape and fdter location occurred. Results All the inferior vena cana filters were successfully emplaeed, and DVT responded well to the filters; no clinical relevant pulmonary embolism occurred; the average time of filter emplacement was 14.0 ± 2.0 days; thrombus was trapped in 24 cases （75%）. Conclusions Retrievable vena cana filter is of exact curative effect in the prevention of PE and high value of clinical application.
