The principle of injection sclerotherapy is to inject a substance that irritates the inside lining of the vein, causing it to become “sticky”. Compression (with stockings) then pushes the walls of the vein together so that it is sealed off with scar tissue and blood clot.
Compression is required after injection to stop large blood clots from forming inside the veins. However, compression is not required if you are only having spider veins treated. Compression should be applied for two days for small veins and for one week for larger veins.
This method has been used for thousands of patients over the past 40 years. In carefully chosen patients, it is safe and effective.
Injection treatment is suitable for:
- spider and reticular veins
- isolated varicose veins
- varicose veins that recur after surgery
- primary varicose veins
