Exploration de la microcirculation : débitmétrie doppler laser

The laser Doppler (LDP), which utilises the Doppler effect, is the only method that allows a continuous assessment of the microcirculation perfusion. The measurement can be made at a unique point with the standard LDP, or on a surface of tissue using LDP– imaging (LDPI). The analysis of the signal allows measuring the perfusion and analysing the vasomotion. Tests of provocation are often used to standardise the measures. The fields of application of LDP are numerous: physiology, pathology, and pharmacology. Raynaud's phenomenon, peripheral arterial disease, ulcers, burns, cosmetics, plastic surgery, and numerous dermatologic pathologies are the most frequent applications. The results are to be interpreted according to the physiological variations of the examined tissue.
