[Lower limb revascularization--a continuous challenge].

Revascularization of the lower extremity in patients with diabetes or chronic obstructive arterial disease is a challenging, still unsolved problem. Modern day technique (stem cell therapy, hyperbaric therapy) has yet to deliver satisfactory results. Homogenous (safenous vein) or heterogeneous (terom, dacron, PTFE-teflon) by-pass surgery is limited because of technical difficulty and positive outcomes have a short duration. All these lead to, in most patients, to amputations as first line therapy or as an alternative to failed approaches. By-pass surgery is limited by graft obstruction. One of the current approaches is the use of omental flap autotransplantation.
