Endovascular Sharp Recanalization for Calcified Femoropopliteal Artery Occlusion
Figure 2
(a) Control angiography reveals a mild plaque in the proximal-middle region of the SFA and a short calcified occlusion in the proximal popliteal artery; distal popliteal artery is observed via few collaterals. (b) Lesion crossing results in subintimal wire tracking and development of the false lumen (black arrows). (c) The calcified occlusion was carefully probed (black arrowheads) by using the stiff end of the Terumo glidewire for sharp recanalization. (d) The true lumen is observed after sharp recanalization (white arrow). (e) Small atherosclerotic emboli are noted in the middle portion of peroneal artery (black arrowhead). (f) Good angiographic results are obtained after subsequent angioplasty and stent implantation.
