Aegisy可回收腔静脉滤器在创伤外科的临床应用

Clinical application of retrievable Aegisy vena cana filter in trauma patients

目的:评价可回收腔静脉滤器在创伤外科预防肺动脉栓塞的安全性和有效性。方法:108例创伤外科病人因下肢深静脉血栓形成而在外科手术前置入可回收下腔静脉滤器,滤器置入后完成骨科手术,手术后次日给予抗凝溶栓药物治疗,每2天复查血D-二聚体浓度,每周复查1次双下肢静脉超声,至下肢静脉无新鲜血栓形成或D-二聚体浓度正常后取出下腔静脉滤器。结果:108例病人的滤器均成功植入预定位置,平均留置时间为11.5(6～21d),期间无一例肺栓塞发生,无滤器闭塞,最迟在21d内全部滤器均成功取出,62例(57.4%)病人在滤器上发现血栓捕获。结论:该观察表明可回收下腔静脉滤器在预防肺动脉栓塞方面是安全有效的,而且全部可安全取出。

Objective To explore the clinical application value of retrievable Aegisy vena cana filter in the prevention of pulmonary embolism （PE） in trauma patients. Methods The filter was placed in via the healthy side femoral vein of 108 cases with acute or deep vein thrombosis （DVT）; 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 filter location occurred. Results All the inferior vena cana filters were successfully emplaced, and DVT responded well to the filters; no clinical relevant pulmonary embolism occurred; the average time of filter emplacement was 11.5 days; thrombus was trapped in 62 cases （57.4%）. Conclusions Retrievable vena cana filter is safe and effective in the prevention of PE for trauma patients and have high value of clinical application.
