Background

The evolution of medical and minimally invasive techni-ques have led to improved outcomes in limb salvage in elderly patients. In particular, has improved the overall survival of the patients and life expectancy. The patient with major amputation have high rates of mortality and morbidity and health care cost with a con-siderable impact on society. The work presented here concerns elderly patients with aorto iliac occlusive disease and limb ischemia with and without ulcers. Today revascularisation technique of choice, in these patients, is the endovascular recanalization. In some cases, this technique is not feasible due to the impossibil-ity to cross the occlusions (about 10 % of the procedures). The aorto- femoral bypass “anatomical ” is to be preferre
