Abstract
Thermal imaging was used for the estimation of lower-limb primary chronic venous diseases connected with an insufficiency of superficial veins. The current study was performed by means of a Thermovision A40 camera. The curves of the chosen regions of interest were performed in a research room with a stabilized temperature. Curves of the lower extremities showed that the patients suffered from a venous insufficiency characterized by a higher skin temperature connected with pathological changes in the veins. Changes seen in the lower extremities skin thermal map may be associated with blood stasis, inflammatory states and swelling. The differences in temperature distribution are due to a correlation between the medical diagnosis and the parameters obtained from duplex scanning. The results of the thermal imaging showed differences between patients’ health may suggest that a thermovision of lower extremities venous diseases can be very useful in medical diagnosis. The correlation was obtained from temperature parameters and duplex scanning. The parameters may suggest that thermovision diagnostics may be useful as a complementary method in the diagnosis of chronic venous diseases in the lower extremities.

The enrolment for the trial was performed in a group of patients with primary chronic disease stages C2–C4 who did not suffer from any other diseases, and in duplex scanning reflux duration [500 ms in the great saphenous vein (GSV) the only deviation was found
Summary
Disease of the venous system is a serious public health problem affecting all Western industrialized countries. The prevalence of lower-limb venous disease in the adult population is estimated to be at 40–50 % for men and 50–55 % for women, whereas visible varicose veins and chronic venous insufficiency are, respectively, present in 10–15 % and 2–7 % of the male population and 20–25 % and 3–7 % of the female population [1]. In the United States, an estimated 23 % of adults have varicose veins, and 6 % have more advanced chronic venous disease (CVD), including skin changes and healed or active venous ulcers [2]. The gold standard, may not show any pathologies in the venous system in the early stages of CVDs, and in some patients, venous disease may only be connected with venous microcirculation disorders. General practitioners and angiologists need an easy and nonivasive technique, which would allow them to diagnosis CVDs in their early stages
