The authors report their experience with 30 caval filters placed throughout 3 years, and compare it with the data from the literature. In 8 patients (26.5%) Gunther filters were used, in 16 cases (53.5%) Filcard filters (4 DF-01 and 12 DF-04) and finally the last 6 patients (20%) were treated with LGM filters. In 18 cases (60%) the filters were positioned through right common femoral vein, whereas in the remaining 12 patients (40%) they were placed through the right internal jugular vein. Early complications were 1 mispositioning (3.3%) with a LGM filter, 2 incomplete opening (6.6%) of Filcard DF-01 filters, 3 significant tiltings (10%) with Filcard DF-04 filters. One patient (3.3%) died one week after the placement of a Gunther filter. The radiologic follow-up, which included controls with conventional radiology, US, cavography, MR and CT revealed no later complications. All the filters exhibited both advantages and disadvantages. Although all the filters commonly in use are effective to prevent pulmonary embolism, further experience is necessary to find out the "ideal" filter.
作者报告了他们在3年中植入30个腔静脉滤器的经验，并与文献数据进行了比较。8例患者（26.5%）使用了Gunther滤器，16例（53.5%）使用了Filcard滤器（4个DF-01和12个DF-04），最后6例患者（20%）使用了LGM滤器。18例（60%）滤器通过右股总静脉置入，其余12例患者（40%）通过右颈内静脉置入。早期并发症包括1例LGM滤器误置（3.3%），2例Filcard DF-01滤器未完全打开（6.6%），3例Filcard DF-04滤器严重倾斜（10%）。1例患者（3.3%）在植入Gunther滤器一周后死亡。包括传统放射学、超声、腔静脉造影、磁共振成像和计算机断层扫描检查在内的影像学随访未发现后期并发症。所有滤器都有优点和缺点。虽然所有常用滤器在预防肺栓塞方面都有效，但还需要更多经验来找出“理想”的滤器。
