Sclerotherapy - 1 or more sessions ?
Sclerotherapy 'success' is multifactorial and depends on:
1) experience, 2) technique (foam or traditional), chemical solution chosen (saline, STS, etc), concentration of chemical used, whether or not adequate compression is used, timing of compression (debated in the literature) and your body's innate abiility to heal (recanalize sclerosed veins).
Multiple sclerotherapy spider vein treatments are typically necessary to obtain optimal results.
Spider vein treatment explained
When you look at your spider veins, what you are really seeing is blood in the veins. Cosmetic resolution depends on getting the blood out of these veins and preventing it from getting back in. Once you have a series of veins injected during sclerotherapy it is your body's response to the medication that determines whether the veins go away or not. After becoming very inflamed, the veins hopefully scar in on themselves preventing any blood from re-entering them. I usually tell my patients to expect about 80% of the veins we inject to improve and or go away after the first treatment.
Bottom line, in general expect to require at least one additional round of injections before you get the results you desire.
Sclerotherapy for spider veins will usually require multiple sessions to get about 80% improvement.

One treatment not the norm.
The treatment of spider veins is a process and usually requires several sessions. If one treatment solves your spider vein problem then you are very fortunate. Most people require 2-3 cycles of treatment and then some maintenance on a 6 month or yearly basis.
