Sclerotherapy


Information

Sclerotherapy is a treatment for the removal of spider veins and smaller varicose veins. A small volume of a sclerosing liquid is injected into the diseased vein, which causes it to seal shut, eliminating the vein completely. Sclerotherapy is a quick in-office procedure and does not require any anesthesia.

Blood circulation is carried out through healthy veins located deeper within the body, so the outward appearance and sometimes pain associated with the problematic veins is significantly reduced.



What to Expect


During the Procedure:

The Area around the vein will be cleaned and sterilized, then your doctor will use a fine needle to slowly insert a solution into the appropriate vein.

The solution, usually in liquid form, works by irritating the lining of the vein, causing it to swell shut and block the flow of blood. Some solutions contain a local anesthetic called lidocaine.

Eventually, the vein will become scar tissue and disappear. Sometimes a foam version of the solution may be used, particularly when a larger vein is involved. Foam tends to cover more surface area than liquid.

Some people experience minor stinging or cramps when the needle is inserted into the vein. If you have a lot of pain, tell your doctor. Pain may occur if the solution leaks from the vein into surrounding tissue.

Once the needle is withdrawn, your doctor applies compression and massages the area to keep blood out of the injected vessel and disperse the solution. A compression pad may be taped onto the injection site to keep the area compressed while your doctor moves on to the next vein.

The number of injections depends on the number and size of veins being treated.


After the Procedure:

You’ll be able to get up and walk around soon after the procedure. Walking and moving your legs is important to prevent the formation of blood clots.

You’ll be asked to wear compression stockings or bandages — usually for about two weeks — to maintain compression on the treated veins.

Most people return to their normal activities on the same day, but it may be wise to have someone drive you home after the procedure. Your doctor will probably advise you to avoid strenuous exercise for two weeks after the procedure.

You’ll also want to avoid sun exposure to the treated areas during that time. The inflammation caused by the injections combined with sun exposure can lead to dark spots on your skin, especially if you already have a dark skin tone
