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.
