Évaluation de la perfusion viscérale et anastomotique par réalité augmentée basée sur la fluorescence

Abstract : The fluorescence-based enhanced reality approach is used to quantify fluorescent signal dynamics and superimpose the perfusion cartography onto laparoscopic images in real time. A colonic ischemia model was chosen to differentiate between different types of ischemia and determine the extension of an ischemic zone in the different layers of the colonic wall. The evaluation of fluorescence dynamics associated with a machine learning approach made it possible to distinguish between arterial and venous ischemia with a good prediction rate. In the second study, quantitative perfusion assessment showed that the extent of ischemia was significantly larger on the mucosal side, and may be underestimated with an exclusive analysis of the serosal side. Two further studies have revealed that fluorescence imaging can guide the surgeon in real time during minimally invasive adrenal surgery, and that quantitative software fluorescence analysis facilitates the distinction between vascularized and ischemic segments.
