Abstract: Persistent sciatic artery (SA) is recognized as a minority variant of embryogenesis of lower limb artery. Article describes a clinical case of complex treatment of a patient with persistent SA, critical ischemia of lower limb and with diabetic foot. The patient underwent diagnostics of lesion, that helped to find out possible ways of disease progression, endovascular revascularization and step-by-step surgery treatment that allowed to keep support function of the limb.

Abstract: This review is focused on the problem of the angiosome principle of revascularization in critical limb ischemia. The blood circulation of the foot is described in accordance with the angiosome concept. Different opinions on the application of the angiosome principle of revascularization in critical lower limb ischemia are presented. Features of the angiosome principle that limit its routine use in clinical practice are described. Also, methods of perfusion evaluation that can be applied at all stages of the treatment process, allow to assess the severity of macro- and microcirculation impairment and result of revascularization are described.
