Peripheral microcircuiation in patients over 60 years with atherosclerosis of lower limb arteries

Abstract

We investigated peripheral microcirculatory blood flow (MBF) by using laser Doppler flowmetry in 146 patients with IIB-IV stage chronic ischemia of lower limbs (CILL) according to the Pokrovsky-Fontaine classification. The objective was to study the state of peripheral MBF while carrying out functional tests in patients over 60 years with IIB-IV stage CILL before and after revascularization of lower limb arteries. When ageing, CILL patients demonstrate a decrease in the peripheral MBF baseline indicators and an increase in the quantity of defects of regulatory mechanisms and functional reserves of microcirculation, which manifest themselves as a severe paradoxical reaction of the microvasculature during an orthostatic test. In the early postoperative period the elderly patients tend to have reduced functional reserves and regulation mechanisms of MBF, with a high volume and degree of severity of MBF paradoxical reactions during an orthostatic test.
