What indicates a successful treatment in vascular laser procedures?

A successful treatment in vascular laser procedures is indicated by a change in color from red to grey. This color change suggests that the targeted blood vessels are effectively being treated. The laser energy damages the blood vessels, leading to coagulation and eventual absorption by the body. As the treatment progresses, the initially red appearance of the vessels may change to a greyish tone, indicating that the treatment has taken effect and that the vessel is no longer functional or visible.

An increase in redness might be a normal reaction to the laser treatment or an indication of inflammation, but it does not signal success in the treatment of vascular lesions. Skin darkening may occur due to pigmentation changes or other reactions, which could signify complications rather than success. The presence of blisters suggests potential damage to the skin, which is not a goal of the therapy and indicates that the treatment may not have been performed successfully. Thus, observing a gradual change from red to grey is the best indicator of effective treatment outcomes in this context.
