Sclerotherapy (spider vein and varicose vein treatment)
Sclerotherapy (SKLER-o-ther-a-pee) is the most common treatment for both spider veins and varicose veins. The doctor uses a needle to inject a liquid chemical into the vein. The chemical causes the vein walls to swell, stick together, and seal shut. This stops the flow of blood, and the vein turns into scar tissue. In a few weeks, the vein should fade. This treatment does not require anesthesia and can be done in your doctor's office. You can return to normal activity right after treatment.
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.
Possible side effects include:
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 varicose veins return. This procedure can be done in a doctor’s office. Possible side effects include skin sores, swelling, injection into an artery by mistake, or deep vein thrombosis (a potentially dangerous blood clot).
