We present a 77-year-old female with heavily calcified chronic total occlusions (CTO) in a superficial femoral artery treated by endovascular therapy using a Wingman crossing catheter, which is an over-the-wire catheter with a metallic blade, controlled manually. The blade could probe and track the calcified cap of CTO, wherein any hydrophilic guidewires or looped wires could not penetrate. Moreover, the Wingman could proceed through the occlusion and introduce a guidewire into distal intramedial lumen as a support catheter. Finally, wire crossing was achieved using a bi-directional approach. The Wingman can be a simple solution for crossing calcified peripheral CTO.
我们报告了一名77岁女性，其股浅动脉存在严重钙化的慢性完全闭塞（CTO），采用Wingman穿刺导管进行血管内治疗，该导管是一种带金属刀片的导丝导管，手动控制。该刀片可探测并追踪CTO的钙化帽，而任何亲水导丝或环行导丝均无法穿透。此外，Wingman可穿过闭塞病变，并将导丝引入远端血管腔内作为支撑导管。最后，采用双向入路实现了导丝通过。Wingman可为穿过钙化的外周CTO提供一种简单的解决方案。
