Introduction:

The critical ischemia is the most severe condition that affects patients with peripheral arterial illness, with tendency to progressive worsening and it is associated with a high rate of major amputation, mortality and poor quality of life.

Objective:

To present a case with critical limb ischemia without revascularization options and the arterialization of the superficial venous system as an alternative to major amputation.

Case presentation:

A case is presented with diagnostic of critical ischemia in the right lower limb with high risk of major amputation and without revascularization options. The patient presented ischemic lesions in the right foot and an occlusive distal pattern in the right lower limb with a calcified hemodynamic pattern. In the arteriography it was found an occlusion of the popliteal artery in its second portion without restitution of the flow. It was carried out the arterialization of the major safena vein by means of conventional surgical treatment from the first portion of the popliteal artery.

Conclusions:

The arterializations of the superficial venous system allowed the patient to save her limb and that discharged from the institution without a major amputation.
