[State of microcirculation in patients with atherosclerotic-aetiology stage IV chronic arterial insufficiency of lower limbs].

The authors have studied the findings of the examination of and therapeutic outcomes in a total of one hundred and thirty-one patients diagnosed with atherosclerotic-aetiology 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 ninety-six 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 micro-circulaiory 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.
