To assess the characteristics of Option and Denali filters and to identify associations between these characteristics in each filter type.
Consecutive patients who underwent Option or Denali filter placement between August 2019 and August 2022 were included in this retrospective study.
A total of 119 patients (Option, n = 60; Denali, n = 59) were included. The retrieval rates were 45.0% for Option filters and 40.7% for Denali filters. The incidence of tilt at placement was higher for Option filters (76.7%) than for Denali filters (11.9%; P < 0.001). The tilt angle of Option filters at placement was correlated with the common iliac vein-inferior vena cava (CIV-IVC) angle. The incidence of tilt angle change after placement was higher for Option filters (74.1%) than for Denali filters (8.3%; P = 0.001). The IVC contraction rate after retrieval of Option is less than Denali (22.2% vs. 87.5%, P < 0.001). The median fluoroscopy time during Option filter retrieval was longer than during Denali filter retrieval. The fluoroscopic time was related to tilt angle during retrieval of Option filters.
Option filters are more likely than Denali filters to tilt at placement, and the tilt angle of Option filters is more prone to change after placement. The tilt angle at placement in Option filters is related to the CIV-IVC angle. Option filters require a longer fluoroscopic time during retrieval than Denali filters, and this increased fluoroscopic time is related to the tilt angle. Denali is more likely to cause IVC constriction after placement.
评估 Option 和 Denali 过滤器的特性，并确定两种类型的过滤器之间的这些特性之间的关联。
回顾性纳入 2019 年 8 月至 2022 年 8 月期间接受 Option 或 Denali 过滤器放置的连续患者。
共纳入 119 例患者（Option 组，n=60；Denali 组，n=59）。Option 过滤器的回收成功率为 45.0%，Denali 过滤器的回收成功率为 40.7%。Option 过滤器的倾斜发生率（76.7%）明显高于 Denali 过滤器（11.9%；P<0.001）。Option 过滤器在放置时的倾斜角度与髂总静脉-下腔静脉（CIV-IVC）角度相关。放置后 Option 过滤器的倾斜角度变化发生率（74.1%）明显高于 Denali 过滤器（8.3%；P=0.001）。回收 Option 过滤器后下腔静脉收缩率低于 Denali（22.2%比 87.5%，P<0.001）。回收 Option 过滤器的透视时间中位数长于回收 Denali 过滤器。透视时间与 Option 过滤器回收时的倾斜角度相关。
Option 过滤器比 Denali 过滤器更有可能在放置时倾斜，且 Option 过滤器的倾斜角度在放置后更易发生变化。放置时 Option 过滤器的倾斜角度与 CIV-IVC 角度相关。回收 Option 过滤器比回收 Denali 过滤器需要更长的透视时间，且透视时间的增加与倾斜角度相关。放置后 Denali 更有可能引起下腔静脉收缩。
