This study will compare the effectiveness of best available surgical treatment with best available endovascular treatment in adults with critical limb ischemia (CLI) who are eligible for both treatment options.
CRITERIA LIST/ QUALIFICATIONS:
Infrainguinal PAOD (occlusive disease of the arteries below the inguinal ligament).
CLI, defined as arterial insufficiency with gangrene, non-healing ischemic ulcer, or rest pain consistent with Rutherford categories 4-6.
Candidate for both endovascular and open infrainguinal revascularization as judged by the treating investigators.
Adequate aortoiliac inflow.
Adequate popliteal, tibial or pedal revascularization target defined as an infrainguinal arterial segment distal to the area of stenosis/occlusion which can support a distal anastomosis of a surgical bypass.
