Simon Nitinol inferior vena cava filters were placed via a transfemoral venous route in 14 patients. The initial seven caval filters were placed using refrigerated saline infused at a slow rate. In these cases, Simon Nitinol filter expansion was explosive and difficult to control. In the next seven caval filters, the saline infusate was partially frozen and delivered at a higher infusion rate. In this group, the Simon Nitinol filter expansion was noticeably slower with improved ability to control filter placement in the inferior vena cava.
14例患者经股静脉途径置入西蒙镍钛诺下腔静脉滤器。最初的7个腔静脉滤器是通过缓慢注入冷藏生理盐水放置的。在这些病例中，西蒙镍钛诺滤器的展开是突发性的且难以控制。在接下来的7个腔静脉滤器放置过程中，注入的生理盐水部分冷冻并以更高的注入速率输送。在这一组中，西蒙镍钛诺滤器的展开明显更慢，在下腔静脉中控制滤器放置的能力有所提高。
