Tibiodistal vein bypass in critical limb ischemia and its role after unsuccessful tibial angioplasty.

This study showed that tibiodistal vein bypass is a feasible, efficient, and safe technique in patients with critical limb ischemia. It provides acceptable primary and secondary patency rates to prevent major amputation and ensure survival. Previous unsuccessful tibial angioplasty had no significant impact on tibiodistal vein bypass outcome. This technique should be part of the armamentarium of vascular surgeons.
