If you hate putting on your bathing suit or shorts because of the unattractive spider veins on your legs then you're not alone. Many women and men suffer from these unsightly veins due to blood flowing in the wrong direction. If you thought they were just something you had to put up with then you may like to learn more about a simple procedure called sclerotherapy. It makes spider veins disappear or at least become much smaller and less visible.

Sclerotherapy - the solution for leg veins

Spider veins on the legs are small lace like blood vessels (0.5 and 1mm in size) on the surface of the skin that may be red or blue in colour. This may be due to blood circulating in the wrong direction causing a back flow. Some people feel embarrassed and goes to great length to cover up the spider veins.

Sclerotherapy or microsclerotherapy is often the first line of treatment to reduce leg veins to make you look and feel better about yourself.

What are spider veins or small varicose veins?

Spider veins or telangiectasias are small thin blood vessels that lie close to the surface of the skin and appear red or blue. These small, enlarged blood vessels may be short, unconnected lines or may be connected in a spider web or cluster pattern. Spider veins can cover a large area of skin and be quite unattractive. They are most common on the thighs, ankles and feet.

What is sclerotherapy?

The procedure involves micro injection of a TGA approved solution in to unwanted vein. The solution acts on the inner lining of the vein, causing it to collapse and shrink so that no more blood can flow through this unwanted vein.

Following the injection the leg is wrapped firmly in a compression bandage which helps the lining of the collapsed vein to stick together. Patients are advised to walk following the procedure which forces the blood to flow through other healthy blood vessels nearby.

This is a simple procedure to reveal your younger, smoother looking legs.

What causes leg veins or spider veins on your legs?

Spider veins on the legs are small lace like blood vessels (0.5 and 1mm in size) on the surface of the skin that may be red or blue in colour. Veins carry deoxygenated blood back to our heart. In our legs, blood is collected in the superficial veins, just below the skin surface, and delivered to deeper veins that run within our calf muscles. The muscular action of our calves and the one way valves inside the veins help to pump the blood against the force of gravity towards the heart. If these valves fail, blood pools in the superficial veins and enlarged. Spider veins are then further influenced by obesity, heredity, pregnancy and menopause.

How does sclerotherapy works?

A micro-injection of a medicated solution goes into the unwanted vein, causing it to close up and shrink so that no more blood can flow through this unwanted vein. Within weeks the unused vein is absorbed by the body and eventually becomes less noticeable.

Are there any side effects with sclerotherapy?

Below are the potential side effects associated with sclerotherapy*:

  • Brown spots. This is probably due to blood escaping at the time of injection into the vein. In most cases, the small mark disappears within 6 months to a year.
  • Bruising. This is usually very small and disappears within 1-2 weeks.
  • Small swelling/welt of the injected site. This usually disappears within a few days.
  • Development of groups of fine red blood vessels. The new appearance of previously unnoticed fine red veins can occur after sclerotherapy. These new very fine veins can occur in 2-3 days or may not be visible for several weeks following treatment. Usually the condition improves in a few months without any specific treatment.
  • Small ulcers at injection sites. Rarely a small ulcer may occur over the injected vein. The ulcer can be successfully treated but it is necessary to inform the treating doctor as soon as possible.
  • Inflammation of treated veins. Rarely the injected veins become inflamed. When this occurs it can be treated with anti-inflammatory medication.
  • Allergic reaction to the solution. Extremely rare allergic reactions may occur with any sclerosing solution. Minor reaction can be treated with anti-histamine medication.
  • Deep vein thrombosis. Very rarely, deep vein thrombosis may develop after the treatment. The chances of developing deep vein thrombosis are about 1 in every 7000 legs treated

*As with all medical procedures, there are potential risks and side effects. It is important to have a thorough discussion with an experienced cosmetic doctor to assess your risks and side effects.
