What is sclerotherapy?
Sclerotherapy treats web-like spider veins and veins under the skin. It is done as liquid or foam sclerotherapy; the doctor chooses the method at the examination according to vein size and location. Foam may be preferred for larger veins.
How is it done?
The principle is the same in both methods: a millimetre-thin needle is inserted into the vein and a sclerosing agent that irritates the inner vein wall (intima) is injected. The treated vein sticks together, closes and is absorbed by the body within a few weeks.
Who is it recommended for?
- Small and medium varicose veins (usually under 3 mm)
- Visible red or purple spider veins on the legs
- Pain or swelling due to venous insufficiency
- Fine varicose veins after pregnancy
- Patients not suitable for surgery
Aftercare
Mild pain, burning, swelling, redness, bruising or dark marks may occur and usually fade over time. Changes in the veins appear over weeks; some patients need more than one session.
- Wear compression stockings for the recommended period
- Do light exercise such as walking and avoid heavy exercise
- Cold compresses can help with swelling in the first 48 hours
- Avoid hot baths and saunas for a while
- Contact your doctor for severe pain or marked swelling
- Attend the planned check-ups
