Sclerotherapy is the most commonly used procedure to treat varicose and spider veins and is performed by injecting a solution (generally a salt 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.
What is Sclerotherapy?
In most cases of sclerotherapy, the salt solution is injected through a very fine needle directly into the vein. At this point, you may experience mild discomfort and cramping for one to two minutes, especially when larger veins are injected. The procedure itself takes approximately 15 to 30 minutes. The number of veins injected in one session varies, and depends on the size and location of the veins, as well as the general medical condition of the patient. Sclerotherapy is performed in the doctor's office and requires that you do not do any aerobic activity for a few days after the procedure.
How To Prepare
Prior to sclerotherapy, you should avoid certain medications. Talk to your doctor about all medicines (including over-the-counter drugs, herbs, and dietary supplements) you are taking. If you need to take an antibiotic before sclerotherapy, contact your doctor. No lotion should be applied to the legs before the procedure.
After The Procedure
You may experience certain side effects after sclerotherapy. There are milder effects, such as itching, which can last for one or two days after the procedure. Also, you may experience raised, red areas at the injection site. These should disappear within a few days. Bruising may also occur around the injection side and can last several days or weeks.
The same vein may need to be treated more than once. Treatments are usually done every 4 to 6 weeks. You may be asked to wear gradient compression stockings after sclerotherapy to help with healing and decrease swelling. This treatment is very effective when done correctly.
There is a type of sclerotherapy called ultrasound-guided sclerotherapy (or echo-sclerotherapy). This type of sclerotherapy uses ultrasound imaging to guide the needle. It can be useful in treating veins that cannot be seen on the skin’s surface. It may be used after surgery or endovenous techniques if the spider veins return. This procedure can be done in a doctor’s office.
