Sclerotherapy of varicose veins and spider veins
Talk to your doctor if there is a possibility that you are pregnant and discuss any recent illness, medical condition, allergies and medications you are taking, including herbal supplements and aspirin. You may be advised to stop taking aspirin, non-steroidal anti-inflammatory drugs (NSAIDs), iron supplements, or blood products for several days before your procedure. Do not apply creams to your legs before or after sclerotherapy. Leave the jewelry at home and wear loose and comfortable clothes. Because you may be asked to wear a gown, you may want to bring a pair of shorts to wear during the procedure.

What is sclerotherapy of varicose veins and spider veins?
Sclerotherapy is a minimally invasive treatment used to treat varicose and spider veins. In the procedure a solution is injected directly into the affected veins which causes them to shrink, and eventually disappear.

Some of the common uses of the procedure
Sclerotherapy is used to improve the cosmetic appearance of spider veins and relieve some of the symptoms associated with spider veins, which include pain, burning, swelling and nighttime cramp. It is the main treatment for small varicose veins in the legs.

The way I should prepare
You should tell your doctor about any medications you are taking, including herbal supplements, and allergies, especially local anesthetics, general anesthesia, or contrast material with iodine (sometimes called "dyes" or "x-ray dyes" "). Your doctor may advise you to stop taking aspirins, non-steroidal anti-inflammatory drugs (NSAIDs), or anticoagulants for a specific time period before the procedure.
You may be asked to stop taking iron supplements.
Also, tell your doctor about recent illnesses or other health problems.
Consult your doctor about any antibiotic medications you may take or ask for safety guidelines to discontinue these medications.
No lotion should be applied to the legs before or after sclerotherapy.
For the test, you should wear comfortable, loose clothing. You may be given a gown to wear during the procedure.
It is recommended that you bring a pair of shorts to wear during the procedure.

The way the computer looks
The procedure uses a thin, thin needle to inject a sterile sclerosing solution into the small veins.

How the procedure works
When the sclerosing solution is injected directly into the varicose or spider veins, it irritates the layer of the vein, causing it to swell and stick. Over time, the vessel becomes scar tissue that disappears from view.

How the procedure is performed
This procedure is often done in outpatients. However, some patients may need hospitalization after the procedure. Please consult your doctor about whether you will be hospitalized or not.
Using a fine needle, the interventional radiologist injects the solvent solution of veins into the varicose and spider veins. As the procedure continues, you will feel small needle punctures and possibly a mild burning sensation. The number of veins treated in a session varies, and depends on the size and site of the veins.
The procedure is usually complete within 30 to 45 minutes.
back to topWhat will I experience during and after the procedure?
You may experience a cramp sensation for one to two minutes when injecting the solution into larger veins.
After treatment, you will be instructed to wear support stockings or wraps to "compress" the treated blood vessels.
You may experience certain side effects after sclerotherapy. The larger varicose veins that have been injected can become bulging and / or hard for several months before being resolved. Raised red areas may appear at injection sites and should disappear within a few days. Brown colored lines or spots are sometimes seen at injection sites. In most cases they disappear within three to six months, but they can be permanent in five percent of cases. There may be cardinals around the injection site that last for several days or weeks.
Spider veins usually respond to sclerotherapy within three to six weeks, and larger veins respond within three to four months. If the veins respond to treatment, they do not reappear. However, new veins may occur over time, and if necessary, you may return for additional injections.

Who interprets the results, and how do they report
Once the procedure is completed, the interventional radiologist can tell you if it has been a technical success or not.
Your interventional radiologist may recommend a follow-up visit after your procedure or treatment has been completed.
The visit may include a physical examination, imaging procedures and blood tests or other laboratory tests. During the follow-up visit, you may discuss with your doctor any changes or side effects you may have experienced from your procedure or treatment.

What are the benefits and risks?
Benefits
Each sclerotherapy session typically results in removal of 50 to 80 percent of injected veins.
Risks
Any procedure in which the skin penetrates carries a risk of infection. The possibility of needing antibiotic treatment occurs in less than one in 1,000 patients.
Risks include the formation of blood clots in the veins, severe inflammation, adverse allergic reactions to the sclerosing solution, and skin lesions that may leave a small but permanent scar.

What are the limitations of sclerotherapy?
Large varicose veins do not respond as well as small ones to sclerotherapy. A few people (less than 10 percent) who undergo sclerotherapy do not respond to injections at all. In these instances, attempts may be made with different solutions or a different method, such as cutaneous laser therapy.
You will not be able to receive treatment for sclerotherapy if you are pregnant or lactating, or have to bed. You have to wait at least three months after giving birth before you can be considered for this procedure.
Phleboctomy is often used with a more comprehensive treatment, including additional procedures such as intravenous catheter ablation using radiofrequency or laser energy. Patients should discuss their individualized treatment plans with their interventional radiologists.
