Endovascular Sharp Recanalization for Calcified Femoropopliteal Artery Occlusion
Figure 1
(a) Total occlusion of the superficial femoral artery (SFA) from the ostium onwards, heavily calcified plaques, and filling of the middle and distal portions of the SFA by collaterals is shown (black arrows). (b) A huge calcified plaque (white arrows) is noted in the proximal portion of the SFA, and this plaque impedes lesion crossing. (c) The stiff end of the Terumo glidewire is used for sharp recanalization. (d) The middle portion of the SFA was observed using a contrast medium that was injected through the right Judkin catheter after sharp recanalization. (e) Stent implantation from the proximal to the distal portion of the SFA is successful, and good angiographic results are noted.
