Critical limb ischemia and the diseased popliteal artery.

The unique anatomical location and particular biomechanical factors affecting the popliteal artery provide a challenge to determine the proper endovascular, surgical, or combined intervention for patients with critical limb ischemia who often require prompt management in the presence of severe lifestyle-limiting symptoms or of the risk of limb loss or both. Herein, we provide an overview and practical guide for endovascular management of popliteal artery disease in the setting of critical limb ischemia.
