FIELD: medicine, cardiology.
SUBSTANCE: one should perform colored duplex sonography by measuring the resistance index in tibial arteries to evaluate the degree of functional insufficiency in lower limbs, that is at R1 being above 1.0 - the first stage, at R1 being 1.0-0.4 - the second stage, at R1 being below 0.4 and up to 0.2 - the third stage and at R1 being below 0.2 - the fourth stage should be detected. The method enables to objectively and quantitatively evaluate ischemic stages in case of occluding arterial diseases of lower limbs.
EFFECT: higher efficiency of evaluation.
