What veins are treated with
Sclerotherapy?
In larger
blood
vessels (usually greater than 3
millimeters), a procedure called sclerotherapy
is used to treat
unwanted blood vessels. A solution,
called a sclerosing
solution, is injected
with a very fine needle directly
into the blood vessel. This
procedure has been used for spider veins
since the 1932 and,
before that, for larger veins. The solution irritates the lining of the vessel,
causing it to swell and stick together and the blood
to clot. Over a period of weeks, the
vessel turns into scar tissue that fades, eventually becoming barely
noticeable or invisible. A single blood vessel may have to be injected more
than once, some weeks apart, depending on its size. In any one treatment
session, a number of vessels can be injected. Occasionally larger varicose
veins are underneath the spider veins. In such cases, some physicians believe
these vessels should be treated before the spider veins. This can be done by sclerotherapy, followed by compression or by a procedure performed by a vascular
surgeon. Other physicians believe that spider veins may be treated by
sclerotherapy without worrying about the varicose veins unless they become
troublesome.
How successful is sclerotherapy?
After several treatments, most patients can expect a 50 to 90 percent
improvement. However, the fading process is gradual. Total disappearance of
spider veins is usually achieved. For people with mostly very small spider
veins, a laser can also be used with good results. Often a combination of
sclerotherapy and laser treatments yields the best outcome.
Can sclerotherapy be used on all skin
types?
Yes. All skin types and skin colors respond equally well.
