Indocyanine green video angiographies help to identify burns requiring operation

Assessment of burn depth and burn wound healing potential

“…Presence and strength of the fluorescence indicate presence and strength of blood flow, expressed as a ratio to normal skin [38]. Recent modification of this technique using videography instead of angiography allows the capturing of dynamic changes in tissue perfusion [39]. Following an intravenous dose of ICG, laser fluorescence videography is used to create a video image of dye uptake and clearance as an indicator of tissue perfusion.…”

Imaging Techniques for Clinical Burn Assessment with a Focus on Multispectral Imaging

“…37 The fluorescent light is captured and translated into a perfusion map that demonstrates vascular degeneration in wounded areas, which is a marker to assess the severity of burned tissue. 38 ICG imaging accurately differentiates burn depth, as shown in several studies. [39][40][41] Because vascular degradation occurs quickly after injury, ICG videoangiography can be used very early following initial burn injury.…”

Segmentation and classification of burn images by color and texture information

“…Some noninvasive techniques analyze the perfusion of the burn wound based on the fact that tissue damage is inversely proportional to the vascularization after the lesion. [40][41][42] Nevertheless, in these procedures it is necessary to supply a vital colorant to the patient by intravenous method and it is essential to have an emergency system. Other experimental techniques analyze the changes in optical properties of the skin related to the changes of its vascularization, 43 although their application environment is, for the moment, exclusively experimental.…”
