[Choice of optimal surgical reconstruction at patients with critical limb ischemia due to infrainguinal atherosclerotic arterial occlusive disease].

One hundred and four patients with atherosclerotic lesion of femoro-popliteal segment and III-IV stage of ischemia underwent vascular surgical procedures. Results of these operations were analyzed depending on state of distal arterial bed. Autovenous femoro-popliteal bypass (FPB) with reversed autovein was performed at 49 (47.1%) patients, femoro-tibial bypass (FTB) with autovein in situ - at 55 (52.9%). Clinical and angiographic variants of favorable and unfavorable prognosis of FBP and FTB are described. It is demonstrated that severe lesion of outflow distal arteries is the main cause of bypasses thrombosis. Protective arteriovenous fistula in the region of FTB distal anastomosis improves significantly short-term results of operation.
