ABSTRACT
Performong reconstructive operations on arteriae is the only way to avoid limb amputation in patients with critical limb ischemia. Whereas reconstructive manipulations on distal arteriae, especially in patients older then 75 years, are often entailed by thrombotic complications. High peripheric vessel resistance is considered to be the crucial factor of the bypass thrombosis. The conducted study demonstrated the efficacy of the use of vena saphena magna collateral tributaries as bypass unload collectors. Femoral distal autovenous in situ reconstruction decreases vessel resistance. Due to the arterial reconstruction with bypass unload using unligated autovenous tributaries the cumulative bypass patency was 75,1% a year after the procedure. 5-year cumulative bypass patency was 53,8%. 5 - year lethality was 28,6%.
