This document has been prepared to help provide you with information about Sclerotherapy for the treatment of spider veins on your legs, its risks, and alternative treatments. It is important that you read this information carefully and completely.
At NoviSkin, we concentrate on the treatment of telangiectasia and small reticular veins (veins smaller than 3mm in diameter). We mainly use Sclerotherapy, which is the treatment of choice for smaller asymptomatic veins. A sclerosing agent, called polidoconal is injected in small quantities into each vein. A vascular surgeon will treat the larger varicose veins first, thereafter, will we continue with the treatment of the smaller spider veins.
This is a cosmetic procedure and will not be covered by your medical aid.
Sclerotherapy is an art, not science and results are unpredictable and vary from person to person. There is no cure for spider veins. The majority of patients who undergo Sclerotherapy will be cleared of their superficial veins or at least see a good improvement. Unfortunately, there is no guarantee that Sclerotherapy will be effective in every case.
The number of treatments needed to clear or improve the spider veins differs from patient to patient depending on the extent of the veins present. The average amount of treatments is:
3 to 4 at 4 weekly intervals. One leg is treated during a ½hour treatment session with a maximal amount of 10ml of sclerosing solution injected at one sitting.
- Before your treatment:
No specific treatment is necessary.
Come to your appointment with a pair of shorts (or a skirt) for easy access to veins and no creams applied to legs.
Please arrive 30 minutes before the scheduled time of treatment to complete the necessary forms and preparations.
- During the treatment:
Sclerosing agent is injected through a very fine needle directly into the vein.
You may experience mild discomfort and cramping for one to two minutes, especially when larger veins are injected.
Compression bandage is applied which should be kept on for 2 days.
The procedure itself takes approximately 15 to 30 minutes.
Mechanism of action
Sclerotherapy involves an injection of a solution directly into the vein. The solution irritates the lining of the blood vessel, causing it to swell and stick together, and the blood to clot. Over time, the vessel turns into scar tissue that fades from view.
Post Care Instructions
- After the veins have been injected small pressure bandages will be placed on each bleeding injection site or a tight compression bandage will be applied to the entire leg and should be left on for 48 hours.
- The compression bandage should apply slight pressure, but at no point should cause pain or loss of feeling in legs, if this occurs the bandage should be slightly loosened.
- After treatment, it is very important to walk around immediately for at least 10 minutes.
- The patient should walk around for 20 minutes a day for 2 weeks post-treatment.
- No strenuous exercise should be done for 2 week
