【Abstract】 Objective To evaluate the thermography appearance and diagnostic value for TAO in lower extremities. Methods 47 Patients with lower extremities TAO were examined using the method of infrared imaging and 21 health people as control. Results In control group, the skin temperature on both lower extremities was similar. The color between large leg and crus was light red, with light green on periphery, genu was light green, dorsal pedal was light blue. In TAO group, the temperature distribution in lower extremities was unregulated. The temperature difference between high temperature area and low temperature area was more than 0.5℃. The temperature in phlebitis area was higher with red while that in thrombus was lower with green, and that in dorsal pedal and toes was lower showed blue. Conclusion The infrared thermography could be directly displayed on TAO area of lower extremities and it is valuable to the diagnosis of TAO.更多还原
