The Microsclerotherapy is the
technique used to treat spider veins or thread veins of the legs. It is a
relatively straightforward procedure which involves injecting a liquid into the
veins which destroys them and causes them to disappear over time.
Sclerotherapy is a form of treatment
where a doctor injects medicine into blood vessels or lymph vessels that causes
them to shrink. It is commonly used to treat varicose veins or so-called spider
veins. The procedure is non-surgical, requiring only an injection
In clinical practice, the most
commonly used sclerosants appear to be hypertonic saline, sodium tetradecyl
sulfate, polidocanol, and glycerine/lidocaine/epinephrine.
In general most patients tolerate the
microsclerotherapy procedure well and do not need any anesthetic agent. The
post-procedure pain is usually localized to the area where the vein was
injected. This pain is not nearly as intense as the pain following the EVTA but
will be noticeable for longer.
In most cases the veins disappear
within three to six months, but can be permanent about five percent of the time
and increasing with a constant treatment. Bruising may occur around the
injection site and can last several days or weeks. In general, spider veins
respond to sclerotherapy in three to six weeks, and larger veins respond in
three to four months.
How many microsclerotherapy
treatments are required? It varies from individual to individual but typically
2-4 treatments are required for the best results. In patients with a few veins,
1-2 sessions will suffice. More treatments are required where veins are more
numerous and extensive.
Generally, you need to wait about six
weeks before undergoing another sclerotherapy session. Studies of sclerotherapy
as a treatment for varicose and spider veins indicate that it has an overall
success rate of about 60 to 80 percent in eliminating treated veins.
You must wear compression stockings
for the first 24 hours after the procedure. After that time, you should continue
to wear them for the next 14 days at all times, except when sleeping.
