Sizing of iliac vein stents remains controversial. We present the first Venovo venous stent (BD/Bard) that was explanted because of worsening of back and leg pain post treatment and analyze data from the first 50 consecutive Venovo venous stents from our center. Stent size was obtained with intravascular ultrasound of the ipsilateral common iliac vein. The data indicate that there is no statistical relationship between the stent size and worsening or emergence of low back and leg pain. Patient-specific factors may be contributing to this extremely rare and persistent pain beyond the 30-day follow-up.
髂静脉支架的尺寸选择仍存在争议。我们首次报告了因治疗后腰背和腿部疼痛加重而取出 Venovo 静脉支架（BD/Bard）的病例，并分析了来自我们中心的前 50 例连续 Venovo 静脉支架的数据。支架尺寸通过对侧髂总静脉的血管内超声获得。数据表明，支架尺寸与腰背和腿部疼痛加重或出现之间没有统计学关系。患者的具体因素可能导致这种极其罕见且持续的疼痛超过 30 天的随访期。
