Sclerotherapy is a treatment with the help of injections. Since a needle is used, this is not a completely painless procedure, but of course, it is far better than surgery. It is a systematic treatment for small reticulate veins that feed spider veins. These reticular veins also feed varicose veins that remain after endovenous laser treatment. Furthermore, patients with perforator veins that cause a skin ulcer opt for Sclerotherapy.
Procedure of Sclerotherapy
You’ll be lying with your legs slightly elevated for the procedure. After cleansing the area to be treated, your doctor will use a fine needle to slowly insert a solution into the right vein.
The solution works by irritating the vein’s lining, causing it to swell shut and restrict blood flow.
Eventually, the vein will disappear as it becomes scar tissue. Sometimes doctors may use a foam version of the solution, particularly when a larger vein is involved. The foam covers more surface area than liquid.
Some people may experience minor stinging when the needle is inserted into the vein. However, if you experience a lot of pain, inform us. Pain may occur if the solution leaks into the surrounding tissue from the vein.
Once the needle is withdrawn, we will apply compression and massage the area to keep blood from the injected vessel and disperse the solution. A compression pad might be taped onto the injection site to keep the area compressed while the doctor moves to the next vein. The number of injections will depend on the number and size of veins being treated.
Care After the Procedure
You’ll be able to walk around hours after the procedure. Walking and moving your legs are important to prevent the formation of blood clots in the treated vein.
You’ll be asked to wear stockings or bandages for about two weeks to maintain compression on veins.
Most people return to normal activities on the same day, but having some friend or relative drive you home after the procedure is wise. In addition, We will probably advise you to avoid heavy exercise for two weeks after the Sclerotherapy procedure.
You’ll be advised to avoid direct sun rays exposure to the treated areas. When combined with sun rays exposure, the inflammation caused by the injections can lead to dark spots on the skin.
If you were treated for varicose veins or spider veins, you could expect to see results three to four weeks after treatment. Larger veins may require more time, like three to four months. However, multiple treatments might be required to achieve the targeted results in some cases. Veins that respond to treatment once generally don’t come back ever. However, new cases of varicose and spider veins may appear.
We will schedule a follow-up visit about a month after the Sclerotherapy procedure to determine how well veins respond to the treatment and if you need more sessions. Generally, we recommend waiting about six weeks before undergoing another sclerotherapy session.
