Endovascular intervention of peripheral chronic total occlusion (CTO) is technically challenging and time consuming. Various techniques and devices are used to facilitate lesion crossing and improve the success rate of the procedure. However, these new devices are quite expensive and not readily available. We report 2 cases of peripheral CTO wherein the occlusions were successfully crossed by using stiff end of Terumo glidewire. This sharp recanalization may be a useful technique for the recanalization of calcified peripheral CTOs when conventional techniques fail and new devices are not readily available, but it is accompanied by the risk of distal atheroembolism.
外周慢性完全闭塞病变(CTO)的血管内介入治疗在技术上具有挑战性且耗时。人们使用各种技术和器械来促进病变通过并提高手术成功率。然而,这些新器械相当昂贵且不易获得。我们报告2例外周CTO病例,其中通过使用泰尔茂滑导丝的硬头成功穿过了闭塞病变。当传统技术失败且新器械不易获得时,这种锐性再通术对于钙化外周CTO的再通可能是一种有用的技术,但它伴随着远端动脉粥样硬化栓塞的风险。
