Treatment of vascular pathologies: choice of laser techniques
Devices for transdermal vascular photocoagulation
Today, in the hands of an aesthetic medicine specialist who is proficient in laser technologies, there are a large number of mechanisms designed to help get rid of aesthetic defects in appearance that are associated with vascular changes.
Pathologically altered skin vessels are a common cosmetic defect. According to statistics, this problem is familiar to more than 30% of people. Vascular pathologies can be both congenital and acquired, while the pathologically altered vessels themselves can lie at different depths and differ in size. The work of researchers on selective photothermolysis laid the foundation for the rapid development of laser transdermal photocoagulation of vessels.
Selective photothermolysis
According to the theory of selective photothermolysis developed by Anderson R. R., Parrish J. and Manstein D., Altshuler G. B., the energy of the laser beam is selectively absorbed by hemoglobin, which leads to heating of the blood inside the vessel. As a result of heating, the lumen of the vessel is obliterated (collapsed).
Other authors believe that heating the endothelium is not enough - it is necessary to heat the thickness of the vessel wall as well to obliterate the lumen of the vessel. The higher the selectivity of the laser wavelength to hemoglobin, the higher the efficiency/safety ratio.
