Minimally invasive endovascular options of angioplasty and stenting can be used to treat distal anastomotic stenoses in lower limb bypass grafts, but stents near the knee joint may fracture. The nitinol helical interwoven structure of the Supera stents (IDEV Technologies Inc., Houston, TX) has improved flexibility and kink resistance. We report a patient who received salvage angioplasty and Supera stenting of the distal anastomosis of femoropopliteal bypass grafts with good mid-term results. Considering the high radial strength and fracture resistance, these Supera stents may be a good treatment option in salvaging failing bypass grafts.
血管成形术和支架置入术等微创血管内治疗方法可用于治疗下肢旁路移植血管的远端吻合口狭窄,但膝关节附近的支架可能会发生断裂。Supera支架(IDEV Technologies Inc.,休斯顿,德克萨斯州)的镍钛诺螺旋交织结构具有更好的柔韧性和抗扭结性。我们报告了1例接受股腘动脉旁路移植血管远端吻合口挽救性血管成形术及Supera支架置入术的患者,中期效果良好。鉴于Supera支架具有较高的径向支撑力和抗断裂性,在挽救功能不良的旁路移植血管方面,这些支架可能是一种不错的治疗选择。
