Angiographic and distant clinical results of open surgical interventions treatment of lesions of the aorto-iliac segment of the lower extremities

Occlusion-stenotic lesions of the arteries (OSPANK) are the main cause of the development of critical ischemia of the lower extremities due to the progressive severe damage to the arterial bed, which results in the failure of hemodynamic and metabolic mechanisms to compensate for the damaging effect of circulatory hypoxia on the tissues of the distal limb.According to modern authors, critical ischemia against the background of progression of atherosclerotic lesions of the lower limbs occurs with a frequency of 50-100 cases per 100 thousand population in North America and europe. At the same time, in almost 25% of patients with OSPANK there is a need for limb amputation. The prevalence and severity of the OSPANK, first of all, affects the age composition of the population. The highest prevalence of OSPANK was noted among patients older than 70 years.
