Femoropopliteal atherosclerosis affects a significant percentage of the world population, leading to intermittent claudication and critical limb ischemia. The femoropopliteal segment has a unique set of biomechanical challenges that must be considered and overcome for treatment. The use of stents is a reality and a necessity in peripheral interventions. The success of first-generation femoropopliteal stents was limited by their rigidity and deformability. The standard nitinol stents overcame certain biomechanical challenges because of their superelasticity and thermal shape memory, although stent fracture is still an issue. Therefore, interwoven nitinol stents with helical structure have been developed, borrowing the concept from biliary stents, aiming to provide good flexibility while still maintaining a uniform cell size and significant radial strength. This unique interwoven structure gains it advantage in the femoropopliteal region. The purpose of this review article is to investigate the current published evidence of the use of self-expandable interwoven nitinol stents in femoropopliteal arterial disease and compare them with other endovascular treatment options.
股腘动脉粥样硬化影响着世界上相当大比例的人口,可导致间歇性跛行和严重肢体缺血。股腘动脉段存在一系列独特的生物力学挑战,治疗时必须加以考虑并克服。在周围血管介入治疗中,支架的使用已成为现实且必不可少。第一代股腘动脉支架的成功受到其刚性和可变形性的限制。标准的镍钛诺支架由于具有超弹性和热形状记忆功能,克服了某些生物力学挑战,尽管支架断裂仍是一个问题。因此,借鉴胆管支架的概念,开发了具有螺旋结构的编织镍钛诺支架,旨在在保持均匀的网格尺寸和显著径向强度的同时提供良好的柔韧性。这种独特的编织结构使其在股腘动脉区域具有优势。这篇综述文章的目的是研究目前已发表的关于自膨胀编织镍钛诺支架用于股腘动脉疾病的证据,并将其与其他血管内治疗选择进行比较。
