Also known as: varicose veins treatment.

What is sclerotherapy?

Sclerotherapy is a medical treatment for varicose veins or spider veins, which are visible, bulging and often aching veins frequently found in the legs. It involves injecting the veins with a solution in order to eliminate or reduce the symptoms of varicose veins.

What happens during the treatment?

The doctor injects the solution into the appropriate veins with a needle. The solution causes the vein the swell shut and block the flow of blood. Eventually it turns into scar tissue and disappears altogether.

Is any special preparation needed?

You may need to avoid certain medications before the procedure.

What are the risk factors?

Swelling, warmth, discomfort, blood clots, air bubbles and allergic reactions are all potential risk factors of sclerotherapy.
