Sclerotherapy is done in the office setting. After cleaning your skin, your doctor will inject a spider vein or small varicose vein using a very small needle. A small amount of fluid is injected into the vein which causes it to close. The blood is then rerouted by your body to the nearest healthy vein.

Before the sclerotherapy treatment, patients hydrate by drinking half a liter of pure water. If they are anxious, they are given oral Valium and codeine prior to the procedure. No anesthesia is used, since a large area is treated in each session. The skin is cleaned with alcohol, which also dilates the blood vessels, making them more visible.

A tiny needle is placed inside an individual capillary. Usually, magnification helps visualize the blood vessel. The technique requires great skill and an extremely steady hand. A small squirt of saline is injected inside the capillary, causing a dramatic clearing of the spider vein. I know I've done well when my nurse says "wow." If the right portion of the capillary is entered, several square centimeters of connecting capillaries can be treated with a single injection.

I work my way around the front of both thighs and legs and then turn the patient on her belly. Next, I treat the backs of the thighs and legs. The most noticeable spider veins are treated in the first session, then progressively smaller vessels in subsequent sessions.

After a capillary is injected, my nurse applies a small piece of foam tape. I inject a maximum of five milliliters of hypertonic saline, giving the patient as much salt as she would get in three and a half portions of large French fries at McDonald's.
