Early Graft Dysfunction Following Kidney Transplantation: Can Thermographic Imaging Play a Predictive Role?

The shortage of organs and the growing need for them over recent years have led to the adoption of less stringent donor acceptance criteria, resulting in the approval of marginal organs for transplant, especially from elderly donors. This implies a higher risk of graft dysfunction, a higher frequency of immunological and vascular complications, and shorter graft survival. Several strategies have been implemented in clinical practice to assess graft quality and suitability for transplantation. We have started to test the prospective intraoperative use of thermo-vision cameras during graft reperfusion. Images were acquired using the FLIR One Pro thermo-vision camera for android devices. We hypothesized that thermal images would give a better perspective about the quality of arterial perfusion and graft revascularization of the renal cortex. Thermo-vision cameras provide an easy-to-use, noninvasive, cost-effective tool for the global assessment of kidney graft cortical microcirculation in the immediate post-reperfusion period, providing additional data on the immediate viability and function of a graft.
