Endovascular techniques for revascularization in chronic limb-threatening ischemia are widely used. One of the problems of recanalization is heavy calcification. Heavy calcification results in difficulty in puncturing a vessel, guidewire passage, balloon crossing, balloon dilatation, stent placement, and short- and long-term outcomes. Although new technologies in endovascular equipment have been developed, crossing a balloon in heavy calcification is still a problem of revascularization. We present a new technique for crossing a heavily calcified lesion using a blunt needle called the Blunt needle Endoluminal Cracking Over Strained Through-and through wire (BECOST).
