We analyzed the thermograms of 80 adult cadaveric kidneys transplanted in the Clinic. The images acquired over the operation area were recorded intraoperatively using a thermovision camera ThermaCAMTM SC500 which detects infra-red radiation and records digital images with surface temperature distribution of tested objects. During the reperfusion of every graft we made 100 thermographic scans each acquired in one second interspaces. We started the recording at the moment of removal of the arterial forceps. The computerized system of image analysis enables to choose the method of the radiation and temperature analysis and to present the obtained results in the form of a text or a diagram. The data analysis of the cold ischemia temperature, rewarming time and temperature of reperfusion demonstrated that average cold ischemia time was +3,2°C, rewarming time 22 min. The average temperature of 80 kidneys in first second after arterial/venous un-clamping was: min. temp. +21,66°C, max temp. +28,14°C and average temp. +24,73°C The lowest temperature was in 8 sec reperfusion when all of preservation liquid was flushed. The registered initial and continuous images of the kidney reperfusion enable to compare temperature distribution and make a qualitative analysis of the efficiency of reperfusion. It is non-contact method that does not disturb during operation and it is saving for graft. These data demonstrate the reperfusion in a new digitally imaging and additional clinical study will help us to develop of this technology in investigative practice.
