Sclerotherapy

Sclerotherapy is the treatment of unwanted abnormal superficial leg veins. Superficial leg veins are usually inherited. They can also occur following pregnancy or weight gain, from standing for long periods or from taking hormonal medication.

Sclerotherapy is not suitable for diabetics, pregnant women and people with poor vein quality.

What is sclerotherapy?

Sclerotherapy is when a solution, usually saline, is injected using an extremely fine needle directly into the unwanted vein. The solution irritates the lining of the vein causing it shrink and fade.

How many treatments will I need?

This is dependent on the severity of the problem and the size of your veins. Most patients require 1-4 sessions spaced 6 weeks apart.

Sclerotherapy is successful for most people. However, it may take a few weeks for any change to be seen, with large veins taking even longer. Some veins need several treatments. Sclerotherapy only treats existing unwanted veins and does not prevent new veins appearing.

What will I experience during treatment?

The needle used for sclerotherapy is extremely fine minimizing discomfort. There may be a mild stinging sensation immediately after the injection as the solution enters the vein. Red and raised areas can occur at the injection sites, these clear within a few days. Small bruises will develop at the injection site but these resolve themselves generally within a week. Immediately after treatment the veins may appear more obvious but this is temporary.

Are there any possible side effects with sclerotherapy?

Long term side effects of sclerotherapy are rare.

A pair of compression or support stockings is supplied following treatment and their appropriate use, as outlined by the doctor, will reduce the risk of Phlebitis, a condition where the treated vein becomes inflamed.

A blush can develop around injection sites. This reaction usually settles within six months. Blushing is more common in women taking the contraceptive pill or post-menopausal hormone replacement therapy.

Brown staining of the skin can develop in treated areas due to leakage of iron pigment from dying veins. This is rare and usually resolves itself.
