Thus, the study aim was evaluation of the value of non-contact foot thermometry, performed using a low-cost infrared medical thermometer, as an adjunct for clinical diagnosis of immediately threatened acute limb ischemia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      It was a single-center observational prospective study performed over 3\u00a0years. Patients with acute limb ischemia of lower limbs grade I\u2013IIB Rutherford treated with urgent revascularization were included. Grade of ischemia was determined independently by two experienced vascular surgeons. Thermometry of the ischemic foot was performed using a medical digital infrared non-contact thermometer (CK-T1501, Cooligg, China) with measuring accuracy of \u00b10.2\u00b0C. Temperature was measured in three points: the dorsal surface of the foot, plantar surface of the foot (both in the metatarsal region), and forehead. The maximal temperature gradient between patient\u2019s forehead and foot (\u2206T\n                      <jats:sub>max<\/jats:sub>\n                      F-F) was calculated.

Only 3 (2%) patients presented rest pain without sensory loss and motor deficit, while the majority were diagnosed with mild (63\/147, 42.8%) or moderate (27\/147, 18.3%) motor deficit. The temperature of the ischemic foot varied from 20 to 36.1\u00b0C, while median value of the temperature was 26.7 [24.5\u201329.9] \u00b0C on the dorsal surface and 26.8 [24.5\u201329.6] \u00b0C on the plantar surface of the foot ( p = 0.85).
