Deep femoral artery often represents an important collateral artery from aortoilac to infrapopliteal region in patients with diffuse arterial occlusion due to arteriosclerosis obliterans. This artery also is commonly spared from severe atherosclerosis. Therefore, arterial reconstruction using the deep femoral artery as an intermediate conduit from the abdominal aorta to the infrapopliteal arteries is an effective bypass surgery to treat the ischemic leg, especially to prevent limb loss in patients with critical limb ischemia. This technique is also useful in patients who need a secondary procedure due to occlusion of the aortofemoral or femoropopliteal graft which was implanted previously. Due to a relatively small size of the distal deep femoral artery, a synthetic vascular prosthesis is used for inflow reconstruction, and a vein graft is applied for outflow bypass. Eleven patients were operated using this technique to treat critical limb ischemia, consisting of 4 primary procedures and 7 secondary procedures. Although one distal graft was occluded due to twist of the vein graft in one month, other 10 grafts remained patent during follow-up period. This technique is especially a useful alternative in the secondary procedure by avoiding dense scar around the common femoral artery which was isolated and anastomosed in the previous operation.
