Introduction. The flow of blood in the arterial and venous vessels of various organs is holds according to the difference of the value of systolic and diastolic pressures and is dependent from many factors connected with the control of the change of the vessel diameter. Arteriosclerosis can make difficult the access of the blood in the essential way to organs laid distally. Available diagnostic methods can increase in the essential way to the quicker intervention in the inhibition of the morbid process.The valuation of usability of method of thermography to rating of haemodynamics changes of blood flow in lower limbs at persons with ischaemia in II period according to Fontaine’a is the aim of study.

Material and methods. Fifty persons was qualified to surveys in II period of the ischaemia of lower limbs, waiting on the endovascular intervention and 49 persons without the affirmed arteriosclerosis of lower limbs, with diseases coexisting characteristic for this aged group. The measurement of the temperature of lower limbs, was made with termographic camera Trotec IR 060.

Results. The assessment of the temperature of lower limbs at persons with their ischaemia showed sig­nificant differences in average values in the comparison with healthy persons (35,4 vs. 36,5°C). The time of duration of the disease moreover was factor determining the evaluation of the changes of the value of the temperature — they diminished together with outflow of time of duration of the disease from 35,8 on 35,1°C in the studied group.

Conclusions. Conducted studies let certify, that morbid process in the character of the ischaemia of lower limbs found reflection in the average values of the temperature on the skin surface of limbs in studied groups carrying out 1.1°C ± 0.7. The results of the examination with the thermographic camera confirmed dependence between the time of duration of the disease and the changes of the temperature of lower limbs. The registration of the range of the flow blood in the arteries of lower limbs made using the thermal photography can provide many interesting information to the valuation of the changes of the circulation in the indicated area.
