Quantitative indicators of microcirculation of the skin of the lower extremities

Abstract

Purpose of the study. To study the quantitative indicators of microcirculation and perfusion of the skin of the lower extremities, taking into account the angiosomal theory. Materials and methods. We studied the microcirculation of the skin of the lower extremities in 31 people, taking into account the angiosomal approach without pathology of the cardiovascular system on the device Easy-LDI company AIMAGO SA (Switzerland). Results. We found that the highest rates of perfusion units on the thigh were found in the pool of the sciatic and posterior arteries, the lowest – in the pool of the deep femoral artery and popliteal artery. On the shin, the highest rates of microcirculation are found in the pool of the posterior tibial artery, the lowest – on the foot. Having such an objective quantitative perfusion index, it is easy to determine the occlusion of the arteries corresponding to the angiosomes, areas of the skin of the lower extremity and to quantify the results of the treatment. Conclusions. The developed indicators of skin perfusion of angiosomes of the lower extremities can normally form the basis for diagnosing the degree of stenosis of the main arteries, serve as an indication for direct and indirect methods of revascularization in obliterating diseases of the arteries of the lower extremities and quantify immediate and long-term treatment.
