Summary

At the digital level, the diagnosis of obstructive arteriopathy is very difficult in the absence of ulcer or of true ischemic signs, and the arteriography, which is an examination to inject an intra-arterial contrast agent, is the reference measure.

The measure by "Laser Doppler" uses a monochromatic light (laser) to measure the concentration as well as the speed of travel of red blood cells in the skin and deduct the cutaneous blood flow.

The great advantage of this technique is that it is non-invasive, inexpensive and can be performed during a consultation. The patient can therefore be briefly informed of the benign (functional) or organic origin of his disorders.
