What is Sclerotherapy of varicose veins and spider veins?
Sclerotherapy is a minimally invasive treatment used to treat varicose and spider veins. The procedure involves the injection of a solution directly into the affected veins, causing them to shrink and eventually disappear.
Whar are some common uses of the procedure?
Sclerotherapy is used to improve the cosmetic appearance of spider veins and to relieve some of the symptoms associated with spider veins, including aching, burning, swelling and night cramps. It is the primary treatment for small varicose veins in the legs.
How should I prepare?
You should report to your doctor all medications that you are taking, including herbal supplements, and if you have any allergies, especially to local anaesthetic medications. Your doctor may advise you to stop taking aspirin, nonsteroidal anti-inflammatory drugs or a blood thinner for a special period of time before your procedure. You may want to bring a pair of shorts to wear during the procedure.
How is the procedure performed?
Using a very fine, thin needle, the doctor will inject the vein dissolving solution into the varicose veins. As the procedure continues, you will feel small needle sticks and possibly a mild burning sensation. The number of veins treated in one session varies, and depends on the size and location of the veins.
How does the procedure work?
When the sclerosing solution is injected directly into the spider or varicose veins, it irritates the lining of the vein, which causes it to swell and stick together. Over time the vessel will die and the body will absorb it.
What will I experience during and after the procedure?
You may experience a cramping sensation for one to two minutes when larger varicose veins are injected. After the procedure you may be instructed to wear a compression stocking to compress the treated vessles. you may experience side effects after sclerotherapy. Larger injected varicose veins may become lumpy and/ or hard for several months before resolving. Raised red areas may appear at the injection sites and should disappear within a few days. Brown lines or spots on the skin may be seen at the injection sites. In most cases they disappear within three to six months, but can be permanent about five percent of the time. Bruising may occur around the injection site and can last several days or weeks.
