Experience of endovascular interventions in treatment of patients with critical ischemia of lower extremities: review of literature

Critical ischemia of the lower extremities is an extremely low circulatory state in the limb that develops in the finals of obliterating arterial diseases and leads to constant patient suffering and, ultimately, to limb loss if blood flow is not restored.An effective means of arresting critical ischemia is to improve blood circulation with balloon angioplasty and stenting of the arteries. This operation can be performed with a positive effect in most patients. However, the effect of angioplasty of the arteries of the shin remains short and after 6-24 months a signifi- cant portion of the angioplasty undergoes reocclusion. In this case, repeated interventions or a shunt are required. In this study, a review of the literature on the successful treatment of CINC was conducted.
