Lower limb capillary dilatation treatment is mainly through physical methods. If the lower limb capillary dilatation is more obvious, and relatively limit, the blood vessels are very fine, this time can be treated through the laser treatment method to carry on the treatment. If the capillary dilatation of the lower limbs is in clusters, and the dilatation of the blood vessels is relatively high, it can be treated by local injection of sclerosing agents, and the sclerosing agents chosen are foam sclerosing agents, such as polycinnamon alcohol and polydocanol. If polydocanol is applied, an injection of the original polydocanol is required, which is able to well destroy the endothelial cells of the capillaries, causing the formation of sterile inflammation of the blood vessels. Eventually it will take about a month to make the capillaries disappear completely through the time of mechanization of the body.
