Abstract

Critical lower limb ischemia with the stages of trophic disorders is the end stage condition of lower extremities. Mostly expedites to disability of the lower limb and unfavorable prognosis in terms of affected limb preservation and mortality. Occlusive pathology in the branches of aortic bifurcation remains an urgent task of endovascular surgery in all highly developed countries throughout the world. Simultaneously, often the pathology is characterized by the atherosclerotic etiology of unilateral or bilateral lesions of the iliac arteries. Critical ischemia of the lower extremities affects about 1% of men over 55 years of age. First line diagnosis of Peripheral arterial disease is Ankle-Brachial Index (ABI). In modern times, for the diagnosis of patients with severe limb threatening ischemia, R.Fontine and WIFI (Wound Ischemia Foot Infection) classifications have been used to assess the severity of the patients (Table 1).
