The authors have studied the findings of the examination of and therapeutic outcomes in a total of one hundred and thirtyone patients diagnosed with atheroscleroticaetiology stage IV chronic arterial insufficiency of the lower extremities. Of these, the dynamic analysis of the tissue blood flow on the background of haemodynamically efficient direct revascularization of the lower limbs was carried out in ninetysix patients. In a further 35 patients, a comprehensive instrumental examination of the blood flow on the background of chronic critical ischaemia was complemented by evaluating the morphological alterations in the skin of the foot of the affected extremity. The findings obtained during the examination made it possible to single out three types of morphofunclional alterations in the microcirculaiory bed (i.e., irreversible, severe reversible, and moderate), as well as to trace the patterns of transformation of the tissue blood flow in each of them on the background of efficient direct revascularization.

KEY WORDS: microcirculation, chronic arterial insufficiency of the lower extremities, critical ischaemia.
