Abstract
This case had previously received endovascular treatment for peripheral arterial disease. However, the left lower limb ischemia had worsened and the toe was necrotic with severe pain. Preoperative computed tomography revealed that the left iliac stent was completely occluded, additionally left common femoral artery and superficial femoral artery and deep femoral artery were occluded. Further, the stent was placed in the right common femoral artery, which made it even more difficult to perform the additional treatment. We successfully treated the critical limb ischemia by extraanatomical bypass (from right femoral artery to left below the knee popliteal artery) with autogenous vein. And the right common femoral stent was removed and patch angioplasty with autogenous vein was performed before the bypass.
