Sclerotherapy for spider veins is a simple, effective and safe method.

This is a very method for treating spider veins and minor varicosities. One of the key benefits is that this procedure is done as an outpatient without any disruption to everyday activities.

The procedure involves the injection of a sclerosant, Aethoxysklerol into the vein using a very fine needle. Each injection treats a small area and therefore, depending on the extent of your spider veins, multiple injections may be required in a single session. Sclerotherapy damages the inner wall of the veins, causing them to collapse and shut down. This will cause the veins to gradually fade over the next 8 to 12 weeks.

Sclerotherapy with Aethoxysklerol is very effective and in around 80% of cases. It is important to note that some patients may require additional sessions to obtain the best results. Some cases may not respond effectively to sclerotherapy. This is not a reflection of how the treatment was performed, but merely there are some resistant veins.

Note that it is impossible to eradicate every last vein, but in suitable cases, sclerotherapy should cause the majority of spider veins to fade or disappear.

This treatment does not prevent the future appearance of new spider veins.

On the day of the procedure

Wear comfortable clothing. Take your regular medications. (Notify Mr Bell if you are taking any blood thinners such as Aspirin).

There is no need to fast. Make sure that you are well hydrated

After the procedure

Walking is recommended for at least 40 minutes each day. Strenuous activity such as jogging and aerobics should be avoided for the first week. Minor bruising, irritation, swelling or tenderness may occur after treatment. This is normal and will resolve within the next two weeks.

Compression stockings will need to be worn for one week, day and night (removed for showering).

Possible side-effects

Haemosiderin staining

Brown pigmentation can occur along the course of the injected vein. This is caused by the release of iron pigments from extravasated red blood cells. This is usually temporary and clears naturally over time, although in up to 5% of patient’s pigmentation may continue after 12 months. Laser therapy can be effective in removing this pigmentation in about 50% of people.

Telangiectatic Matting

This is the development of a small network of fine capillaries after treatment. This can occur in up to 30% of patients. The incidence can be reduced to 5% with the wearing of compression after treatment. Telangiectatic matting usually resolves spontaneously over 3-12 months. It may persist longer than 1 year in less than 1% of people.

Deep Vein Thrombosis

This is extremely rare following sclerotherapy, occurring in less than 0.1% of patients, especially if patients follow instructions regarding stockings and walking.
