Atherectomy, the removal of plaque from diseased vessels, is theoretically appealing with respect to various procedures used for revascularization of lower extremity vessels. Instead of damaging the native vessel by pushing aside plaque with a balloon or stent, the plaque is removed. Many atherectomy devices have been designed in attempts to achieve this goal. The SilverHawk device is the latest percutaneous device employing this treatment strategy. We discuss patient selection, technical considerations, and strategies for both above and below the knee revascularization, as well as pitfalls in each location based on our experience with over 200 patients.
斑块旋切术,即从病变血管中清除斑块,对于用于下肢血管血运重建的各种手术来说,在理论上颇具吸引力。该手术不是通过用球囊或支架将斑块推开从而损伤自身血管,而是直接清除斑块。为实现这一目标,人们设计了许多斑块旋切装置。SilverHawk装置是采用这种治疗策略的最新经皮装置。基于我们对200多名患者的经验,我们讨论了患者选择、技术考量以及膝上和膝下血管血运重建的策略,以及每个部位的陷阱。
