Buenos Aires, Argentina As a consequence of the increase in patients who come to our hospital diagnosed with Peripheral Vascular Disease (PVD) and a significant number of them present Critical Ischemia of the Lower Limbs (ICMI); We started a study with the aim of stratifying the distribution of obstructions and/or occlusions in the arterial circuit of the lower limbs of these patients and recording the cardiovascular risk factors present in patients with ICMI.This study was carried out for 3 years, where 785 patients diagnosed with PVD were evaluated and of these, 200 patients (25.4%) presented ICMI, in the study it was possible to show that this pathology predominates in the male sex, that among the cardiovascular risk factors diabetes mellitus is present in more than half of the population studied, that smoking is a cause that increases atherosclerotic disease making possible its evolution and worsening of the disease.ICMI, being a pathology generally of chronic evolution, its arterial distribution is mainly presented as lesions that cover different areas in the arterial circuit and its presence predominates in the Femoropopliteal and Infrapopliteal joint sectors, it was observed that the longest obstructions are present in the region infrapopliteal artery with an average of 180 mm in length and that the occlusions in this pathology occur more frequently in the posterior tibial artery critical lower limb ischemia, peripheral vascular disease http://www.raci.com.ar/contenido/art.php?recordID=MjQyNA== http://recursos.meducatium.com.ar/contenido/articulos/31700630066_2424/pdf/31700630066.pdf
